Education plays a very important role in molding a person into a good individual by imparting knowledge in all aspects. Globalization has helped the students to go to different countries, attain knowledge and exposure on the culture of that country. Universities receive several hundreds of applications from all over the world to get admission for higher studies. By following the conventional method the faculty of the university and also the applicant will face lot of difficulties in communicating. In conventional method the acceptance or rejection would be generally intimated through post. The applicant will be in complete ignorance during the processing of application. They will be several scenarios where interaction between them is necessary to further process the application. This project is intended to overcome such problems and make the interaction between the staff and applicant smoother. The main objective of the project is to develop a website for Computing and Information Sciences department which manages the data regarding the prospective students as well as students currently enrolled. It can be accessed by prospective students (who wish to join the university), faculty and administrators. Applicant will be notified constantly through email and they can always check their application status online. The role of the administrators is to accept applications sent by prospective students and upload their details such as their GRE, TOEFL scores and their academic records into the database. Once these details are stored in the database, the students will be able to access their application status. Students are also given information about missing documents in the database. There will be a committee to decide the application status whether it will be rejected or accepted. Once the applicant is accepted, the applicant would be added to the current students list. All this process is made easy through this website.

Full textAbstract:
Many clustering algorithms have been developed and improved over the years to cater for large scale data clustering. However, much of this work has been in developing numeric based algorithms that use efficient summarisations to scale to large data sets. There is a growing need for scalable categorical clustering algorithms as, although numeric based algorithms can be adapted to categorical data, they do not always produce good results. This thesis presents a categorical conceptual clustering algorithm that can scale to large data sets using appropriate data summarisations. Data mining is distinguished from machine learning by the use of larger data sets that are often stored in database management systems (DBMSs). Many clustering algorithms require data to be extracted from the DBMS and reformatted for input to the algorithm. This thesis presents an approach that integrates conceptual clustering with a DBMS. The presented approach makes the algorithm main memory independent and supports on-line data mining.

Full textAbstract:
If a single operating system can support multitudes of different programming languages and data structures, a database system can support a variety of data models and data languages. In this thesis, a Kernel Database System (KDS) supporting classical data models and data languages (i.e., hierarchical, network, relational, and functional) is used to support a demonstration object oriented data model and data language. This thesis extends previous research by accommodating an object-oriented-data-model-and-language interface in the KDS. Consequently, the research shows that it is feasible to use the KDS to support modem data models and languages as well as classical ones. This thesis details the KDS design, Insert operation, and Display function. This thesis also details how to implement modifications to the Test-Interface so that the KDS can support the object-oriented database. This thesis proves complex data structures in an object-oriented data model can be realized using an attribute-based data model which is the kernel data model of the KDS. Second, it details how the KDS is designed showing why no changes needed to be made to the KDS to implement the object-oriented toy database. Third, it argues the advantages of using a KDS in the database-system design. The KDS design produces savings in costs from compatability, reduced training, expandability, and software reuse.

Full textAbstract:
It is not revolutionary to say that repetition and practical experience is a very important aspect in learning about and understanding a topic. This is especially true for languages, particularly from the point of view of vocabulary.Like in many other processes that deal with gaining knowledge, studying foreign words involves a lot of side work: For instance the selection of words, or their presentation for the actual training.The purpose of this thesis is to automate the study of vocabulary. To do so, an intelligent software package was developed. Divided into three parts the project takes into account the aspects from the language point of view, from the studying point of view, and from the computer science point of view.The fundamental idea to accomplish the goal is a relational database system. It is utilized by software programs that solve their tasks in respect to data management, data manipulation, storage and retrieval, in an efficient way.The system is developed for English speaking persons studying German as a foreign language. And with every language having its own nature, it naturally influences all levels and aspects of design and utilization of the database.l:Department of Computer Science

Full textAbstract:
This report describes in detail the working process of constructing a normalized relational database with an associated graphical user interface, based on raw data data sets in CSV-format acquired from the Avian Knowledge Network. The data files contained the bird sightings from the year 2009 in North America. An entity-relationship model of the database was designed, including a table representing the raw data as well as tables representing the corresponding normalized relational data. As a first step the bulk loading facility of the DBMS is used for loading a CSV file into the raw data table. Then a SQL stored procedure is used for populating the final relational tables by transforming and cleaning the rows of the raw data table. Performance measurements were made about the data transformation as well as a comparison between querying the raw data table versus the final normalized tables. In addition a graphical user interface (GUI) was developed that allows a user to query the database in a flexible way. The performance measurements indicated that querying the normalized tables was more efficient than querying the raw data table.

Full textAbstract:
Large amount of data is used by companies to enable good analysis of their system’s workability. Data can be stored in a partitioned database, to enable an optimal way of accessing the data. The problem with partitioning is that the complexity of the database structure increases. Therefore retrieving data demands higher expertise of the user. This degree project will examine different solutions to create an efficient and easy to use method, to access and retrieve data from a database with such architecture. Interviews have been conducted at Ericsson and were an important source of information. Existing query builders were another source - they were analyzed for comparison and ideas. As result of research and development, a customized query builder was created. It was adapted to Ericsson’s database environment and internal software. The SQL-queries are generated dynamically using the query builder that was developed in this degree project. The query builder takes input parameters, interpret them and then generate a query. It was implemented in C++, and satisfies specific demands and functionality.Stora mängder data används av företag för att skapa bra analyser av deras systems prestanda. Denna data kan lagras i partitionerade databaser, för att möjliggöra optimal hämtning av data. Problemet med partitionering är att det skapar komplex databasstruktur, därmed ökar kraven på användaren i samband med inhämtning av data. I detta examensarbete kommer vi att undersöka olika lösningar för att skapa en effektiv och lättanvändlig metod för att få åtkomst och hämta data från en partitionerad databas. Intervjuer har genomförts med anställda på Ericsson, som tillsammans med litteraturstudier har varit vår främsta informationskälla. Resultatet av våran undersökning och utveckling blev en specialanpassad query builder. Den är anpassad för Ericssons databasmiljö och interna system. SQL-frågor kommer att genereras dynamiskt utav vår query builder. Denna query builder kommer att ta emot indata, vilket den sedan kommer att tolka och utifrån detta skapa en SQL-förfrågan. Query buildern är uppbyggd i C++, och tillfredställer givna krav på funktionallitet.

The quest to build anthropomorphic machines has led researchers to focus on knowledge and the manipulation thereof. Recently, the expert system was proposed as a solution, working well in small, well understood domains. However these initial attempts highlighted the tedious process associated with building systems to display intelligence, the most notable being the Knowledge Acquisition Bottleneck. Attempts to circumvent this problem have led researchers to propose the use of machine learning databases as a source of knowledge. Attempts to utilise databases as sources of knowledge has led to the development Database-Driven Expert Systems. Furthermore, it has been ascertained that a requisite for intelligent systems is powerful computation. In response to these problems and proposals, a new type of database-driven expert system, Cogitator is proposed. It is shown to circumvent the Knowledge Acquisition Bottleneck and posess many other advantages over both traditional expert systems and connectionist systems, whilst having non-serious disadvantages.KMBT_223

Full textAbstract:
Systems are developed to fulfill certain requirements. Several system design configurations usually can fulfill the technical requirements, but at different equivalent life-cycle costs. The problem is how to manipulate and evaluate different system configurations so that the required system effectiveness can be achieved at a minimum equivalent cost. It is also important to have a good definition of all the major consequences of each design configuration. For each alternative configuration considered, it is useful to know the number of units to deploy, the inventory and other logistic requirements, as well as the sensitivity of the system to changes in input variable values.
An intelligent relational database management system is defined to solve the problem described. Table structures are defined to maintain the required data elements and algorithms are constructed to manipulate the data to provide the necessary information. The methodology is as follows: Customer requirements are analyzed in functional terms. Feasible design alternatives are considered and defined as system design configurations. The reliability characteristics of each system configuration are determined, initially from a system-level allocation, and later determined from test and evaluation data. A maintenance analysis is conducted to determine the inventory requirements (using reliability data) and the other logistic requirements for each design configuration. A vector of effectiveness measures can be developed for each customer, depending on objectives, constraints, and risks. These effectiveness measures, consisting of a combination of performance and cost measures, are used to aid in objectively deciding which alternative is preferred.
Relationships are defined between the user requirements, the reliability and maintainability of the system, the number of units deployed, the inventory level, and other logistic characteristics of the system. A heuristic procedure is developed to interactively manipulate these parameters to obtain a good solution to the problem with technical performance and cost measures as criteria. Although it is not guaranteed that the optimal solution will be found, a feasible solution close to the optimal will be found. Eventually the user will have, at any time, the ability to change the value of any parameter modeled. The impact on the total system will subsequently be made visible.Master of Science

Full textAbstract:
The use of databases has become an integral part of modern human life. Often the data
contained within databases has substantial value to enterprises and individuals. As
databases become a greater part of people’s daily lives, it becomes increasingly interlinked with human behaviour. Negative aspects of this behaviour might include criminal activity,
negligence and malicious intent. In these scenarios a forensic investigation is required to collect evidence to determine what happened on a crime scene and who is responsible for the crime. A large amount of the research that is available focuses on digital forensics,
database security and databases in general but little research exists on database forensics as such. It is difficult for a forensic investigator to conduct an investigation on a DBMS due to limited information on the subject and an absence of a standard approach to follow during a forensic investigation. Investigators therefore have to reference disparate sources of information on the topic of database forensics in order to compile a self-invented approach to investigating a database. A subsequent effect of this lack of research is that compromised DBMSs (DBMSs that have been attacked and so behave abnormally) are not considered or understood in the database forensics field. The concept of compromised DBMSs was illustrated in an article by Olivier who suggested that the ANSI/SPARC model can be used to assist in a forensic investigation on a compromised DBMS. Based on the ANSI/SPARC model, the DBMS was divided into four layers known as the data model, data dictionary, application schema and application data. The extensional nature of the first three layers can influence the application data layer and ultimately manipulate the results produced on the application data layer. Thus, it becomes problematic to conduct a forensic investigation on a DBMS if the integrity of the extensional layers is in question and hence the results on the application data layer cannot be trusted. In order to recover the integrity of a layer of the DBMS a clean layer (newly installed layer) could be used but clean layers are not easy or always possible to configure on a DBMS depending on the forensic scenario. Therefore a combination of clean and existing layers can be used to do a forensic investigation on a DBMS.
PROBLEM STATEMENT
The problem to be addressed is how to construct the appropriate combination of clean and existing layers for a forensic investigation on a compromised DBMS, and ensure the
integrity of the forensic results.
APPROACH
The study divides the relational DBMS into four abstract layers, illustrates how the layers
can be prepared to be either in a found or clean forensic state, and experimentally
combines the prepared layers of the DBMS according to the forensic scenario. The study
commences with background on the subjects of databases, digital forensics and database forensics respectively to give the reader an overview of the literature that already exists in these relevant fields. The study then discusses the four abstract layers of the DBMS and explains how the layers could influence one another. The clean and found environments are introduced due to the fact that the DBMS is different to technologies where digital forensics has already been researched. The study then discusses each of the extensional abstract layers individually, and how and why an abstract layer can be converted to a clean or found state. A discussion of each extensional layer is required to understand how unique each layer of the DBMS is and how these layers could be combined in a way that enables a forensic investigator to conduct a forensic investigation on a compromised DBMS. It is illustrated that each layer is unique and could be corrupted in various ways. Therefore,
each layer must be studied individually in a forensic context before all four layers are
considered collectively. A forensic study is conducted on each abstract layer of the DBMS
that has the potential to influence other layers to deliver incorrect results. Ultimately, the
DBMS will be used as a forensic tool to extract evidence from its own encrypted data and
data structures. Therefore, the last chapter shall illustrate how a forensic investigator can
prepare a trustworthy forensic environment where a forensic investigation could be
conducted on an entire PostgreSQL DBMS by constructing a combination of the
appropriate forensic states of the abstract layers.
RESULTS
The result of this study yields an empirically demonstrated approach on how to deal with a compromised DBMS during a forensic investigation by making use of a combination of
various states of abstract layers in the DBMS. Approaches are suggested on how to deal
with a forensic query on the data model, data dictionary and application schema layer of
the DBMS. A forensic process is suggested on how to prepare the DBMS to extract
evidence from the DBMS. Another function of this study is that it advises forensic
investigators to consider alternative possibilities on how the DBMS could be attacked.
These alternatives might not have been considered during investigations on DBMSs to
date. Our methods have been tested at hand of a practical example and have delivered
promising results.Dissertation (MEng)--University of Pretoria, 2013.

Full textAbstract:
Temporal database management systems provide integrated support for the storage and retrieval of time-varying information. Despite the extensive research which has been performed in this area over the last fifteen years, no commercial products exist and few viable prototypes have been constructed. It is our thesis that through the use of the proper abstractions, it is possible to construct a temporal database management system with robust semantics, without sacrificing performance, and with minimal implementation cost. Our approach parallels the development of relational database management systems, beginning with a theoretically sound abstract model, and then developing the underlying techniques to efficiently implement it. The major theme underlying this research is practicality, in terms of both semantics and implementation. We will show that expressive temporal semantics can be supported while still maintaining reasonable performance, and with relatively small implementation effort. This is made possible, in part, by minimally extending the relational model to support time, thereby allowing the reuse or easy adaptation of well-established relational technology. In particular, we investigate how relational database design, algebras, architectures, and query evaluation can be adapted or extended to the temporal context. Our aim is that software vendors could incorporate these results into existing non-temporal, commercial products with relatively small effort.

Progeny is a project, under D331, that trains Atlantic Bottlenose Dolphins (Tursiops Truncatus). Progeny was designed to explore the standardization of training, husbandry, and record keeping techniques that contribute to preparing, operating, and maintaining dolphins for Fleet systems. Presently, hand written forms are filled out to record data as trainers conduct their training exercises. These forms become the source for creating reports. The current data collection process is tedious, time-consuming, and potentially unmanageable for the staff. This thesis project provides a means to organize, gather, and maintain all the historical, current, and future data for the Progeny project. Capabilities are needed to gather the data so that timely, meaningful information, such as reports and graphs, can be made accessible to the staff. The deliverables from this study are the development of a relational database system for organizing and storing Progeny's data, and the development of an application for entering and accessing the data within the relational database.

Full textAbstract:
Intrusion detection is difficult to accomplish when attempting to employ current methodologies when considering the database and the authorized entity. It is a common understanding that current methodologies focus on the network architecture rather than the database, which is not an adequate solution when considering the insider threat. Recent findings suggest that many have attempted to address this concern with the utilization of various detection methodologies in the areas of database authorization, security policy management and behavior analysis but have not been able to find an adequate solution to achieve the level of detection that is required.
While each of these methodologies has been addressed on an individual basis, there has been very limited work to address the methodologies as a single entity in an attempt to function within the detection environment in a harmonious fashion. Authorization is at the heart of most database implementations however, is not enough to prevent a rogue, authorized entity from instantiating a malicious action. Similarly, eliminating the current security policies only exacerbates the problem due to a lack of knowledge in a fashion when the policies have been modified. The behavior of the authorized entity is the most significant concern in terms of intrusion detection. However, behavior identification methodologies alone will not produce a complete solution. The detection of the insider threat during database access by merging the individual intrusion detection methodologies as noted will be investigated.
To achieve the goal, this research is proposing the creation of a procedural framework to be implemented as a precursor to the effecting of the data retrieval statement. The intrusion model and probability thresholds will be built utilizing the intrusion detection standards as put forth in research and industry. Once an intrusion has been indicated, the appropriate notifications will be distributed for further action by the security administrator while the transaction will continue to completion.
This research is proposing the development of a Database Intrusion Detection framework with the introduction of a process as defined in this research, to be implemented prior to data retrieval. This addition will enable an effective and robust methodology to determine the probability of an intrusion by the authorized entity, which will ultimately address the insider threat phenomena.

Full textAbstract:
A sophisticated database application generation environment known as DB4GL has been developed at Sheffield City Polytechnic. A unique feature of DB4GL is the object-oriented application model used to specify and generate database applications. Although DB4GL has many advanced and powerful features, such as a self-describing data dictionary and extensive integrity rule processing facilities; the system has not been designed for high performance in either the generation tools or the generated database applications. The Parallel-DB4GL (P-DB4GL) project represents an attempt to improve the performance of the generated database applications, by constructing a new concurrent implementation of DB4GL for execution on transputer-based parallel hardware. This thesis describes the DB4GL system as developed to the commencement of the P-DB4GL project. A prototype P-DB4GL system has been implemented that demonstrates how significant performance gains can be obtained from a concurrent implementation on transputer-based parallel hardware. Based on the successful results of this prototype system, designs for a fully functional multiprocessor P-DB4GL system are proposed. The details of this prototype and the fully functional designs are presented in this thesis. The thesis also provides an evaluation of the P-DB4GL project as a whole, and concludes with some suggestions for further research in the areas of parallel databases and object-oriented system implementation.

Full textAbstract:
For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption. Zirconium alloys are exposed to a very severe environment during the nuclear fission process and there is a demand for better design of this material. To meet this requirement a thermodynamic database is useful to support material designers. In this thesis some aspects of the development of a thermodynamic database for zirconium alloys are presented. A thermodynamic database represents an important facility in applying thermodynamic equilibrium calculations for a given material providing: 1) relevant information about the thermodynamic properties of the alloys e.g. amount and composition of phases, oxygen activity, heat capacity etc, and 2) significant information for the manufacturing process e.g. heat treatment temperature. The basic information in the database is first the unary data, i.e. pure elements; those are taken from the compilation of the Scientific Group Thermodata Europe (SGTE) and then the binary and ternary systems. All phases present in those binary and ternary systems are described by means of the Gibbs energy as a function of composition and temperature. Many of those binary systems have been taken from published or unpublished works and others have been assessed in the present work. The elements included in the databse are: C, Fe, Cr, Nb, Ni, Mo, O, Si, Sn, and Zr + H, and the assessment performed under this thesis are: Cr-Sn, Mo-Zr, Sn-Zr, Fe-Nb-Zr and Nb-O-Zr. All the calculations have been made using Thermo-Calc software and the representation of the Gibbs energy obtained by applying Calphad technique with some use of ab initio calculations.QC 20100902

The promise of the Electronic Medical Record (EMR) to store, retrieve, and communicate medical information effectively for a caregiver team has remained largely unfulfilled since its advent in the late 1960's. Previous studies have cited that the communication function of the EMR is critical to its successful adoption. Based on Mediated Agent Interaction theory, this study proposes a message-based model of transmission of clinical information in the EMR. This model is implemented on an existing ICU clinical database, MIMIC II, to produce a database of transmission events. Three metrics for information transmission are derived from exploratory and object-attribute analyses: transmission volume, duration, and load (or rate). Also derived is a set of features that includes a patient's clinical conditions (with acuity scores and mortality), caregiver type and distribution, care-unit locations, duration of care, and types of clinical records. This list of features is reduced to a set of explanatory variables using correlation and univariate logistic regression. Bayesian Network (BN) models are constructed to predict levels of the transmission metrics. BN models show high prediction accuracy for measuring various levels of messaging volume and load, but marginal accuracy for messaging duration. Results from these methods suggest that the volume of information transmitted in the ICU for adult patients is primarily through charts entered by nurses and respiratory technicians (RTs). The amount of data recorded by RTs increases for patients with higher acuity scores, but transmission from nurses decreases for these patients. The rate at which information is transmitted in the ICU for adult patients is directly related to the rate at which notes and charts are entered, as well as the care-unit location where the data is recorded. Further study is required to investigate factors influencing the length of time information is transmitted in the ICU. This study's findings are based on data recorded by caregivers as clinical observations. Further study is necessary to corroborate these results with clinical communications data, including evidence of reception of clinical information by caregivers. The model proposed by this study may be used as a basis for future research and to discover other patterns of clinical communications.

With the wide availability of huge amounts of data and the imminent demands to transform the raw data into useful information and knowledge, data mining has become an important research field both in the database area and the machine learning areas. Data mining is defined as the process to solve problems by analyzing data already present in the database and discovering knowledge in the data. Database systems provide efficient data storage, fast access structures and a wide variety of indexing methods to speed up data retrieval. Machine learning provides theory support for most of the popular data mining algorithms. Weka-DB combines properties of these two areas to improve the scalability of Weka, which is an open source machine learning software package. Weka implements most of the machine learning algorithms using main memory based data structure, so it cannot handle large datasets that cannot fit into main memory. Weka-DB is implemented to store the data into and access the data from DB2, so it achieves better scalability than Weka. However, the speed of Weka-DB is much slower than Weka because secondary storage access is more expensive than main memory access. In this thesis we extend Weka-DB with a buffer management component to improve the performance of Weka-DB. Furthermore, we increase the scalability of Weka-DB even further by putting further data structures into the database, which uses a buffer to access the data in database. Furthermore, we explore another method to improve the speed of the algorithms, which takes advantage of the data access properties of machine learning algorithms.

Database (DB) modelling, like other analysis and design tasks, can only be learnt through extensive practice. Conventionally, DB modelling is taught in a classroom environment where the instructor demonstrates the task using typical examples and students practise modelling in labs or tutorials. Although one-to-one human tutoring is the most effective mode of teaching, there will never be sufficient resources to provide individualised attention to each and every student. However, Intelligent Teaching Systems (ITS) offer bright prospects to fulfilling the goal of providing individualised pedagogical sessions to all students. Studies have shown that ITSs with problem-solving environments are ideal tools for enhancing learning in domains where extensive practice is essential. This thesis describes the design, implementation and evaluation of an ITS named KERMIT, developed for the popular database modelling technique, Entity Relationship (ER) modelling. KERMIT, the Knowledge-based Entity Relationship Modelling Intelligent Tutor, is developed as a problem-solving environment in which students can practice their ER modelling skills with the individualised assistance of the system. KERMIT presents a description of a scenario for which the student models a database using ER modelling constructs. The student can ask for guidance from the system during any stage of the problem solving process, and KERMIT evaluates the solution and presents feedback on its errors. The system adapts to each individual student by providing individualised hint messages and selecting new problems that best suit the student.
The effectiveness of KERMIT was tested by three evaluations. The first was a think-aloud study to gain first-hand experience of the student's perception of the system. The second study, conducted as a classroom experiment, yielded some positive results, considering the time limitations and the instabilities of the system.
The third evaluation, a similar classroom experiment, clearly demonstrated the effectiveness of KERMIT as a teaching system. Students were divided into an experimental group that interacted with KERMIT and a control group that used a conventional drawing tool to practice ER modelling. Both group's learning was monitored by pre- and post-tests, and a questionnaire recorded their perception of the system. The results of the study showed that students using KERMIT showed a significantly higher gain in their post-test. Their responses to the questionnaire reaffirmed their positive perception of KERMIT. The usefulness of feedback from the system and the amount learnt from the system was also on a significantly higher scale. Their free-form comments were also very positive.
