Abstract:
This article is devoted to the comparison of two object-relational mapping systems supported by .NET platform - Entity Framework Core and NHibernate. The research hypothesis “framework NHibernate is more efficient than Entity Framework Core in the context of DML operations” was put forward. In order to make an efficiency analysis of ORM frameworks, a desktop application was designed and implemented to enable testing and visualization of results. The NHibernate framework turned out to be much more efficient than Entity Framework Core in single tests and slightly faster in bulk tests. The stability of both frameworks was similar.

Abstract:
Abstract During object-relational database physical structure design, problems are caused by three factors: ambiguity of transformations of conceptual model, multiplicity of quality assessment criteria, and a lack of constructive model. In the present study a constructive hierarchical model of physical database structure has been developed. Implementations are used in XML, SQL and Java languages. Multi-criterial structure optimisation method has also been developed. Structure variation space is generated using transformation rule database. Prototype has been implemented within the framework of the research.

Abstract:
In this article, the author explains a contemporary framework for psychoanalytic organisation theory and identity. In doing so, he assumes a post-Kleinian object relational approach. This orientation to understanding the complexity of organisations and organising takes advantage of the ideas of Winnicott and Ogden. The notion of organisational identity and the process of identification are viewed from experiential, relational and intersubjective psychodynamics. Organisational members are engaged in three modes of organising: depressive (containment versus control); paranoid-schizoid (division versus fragmentation); and autistic-contiguous (integration versus isolation). Finally, the discovery of organisational identity depends on the collection of psychoanalytic data that involve the observation and interpretation of intersubjectivity rooted in the experience of organisational membership.

Full text
Abstract:
The term impedance mismatch was first used in 1984 to label problems that arise when a program uses a relational database for storage. For example, when transferring data from a relational database into a program any relational data structure is lost because a program operates at the row level. Consequently that data structure must somehow be reproduced when data is returned to a database. There are many such mismatches that cost time and effort to address. As new programming and database languages are introduced other kinds of impedance mismatch are anticipated. Traditional approaches are concerned with pragmatic solutions to specific problems of implementation. They do not address the underlying cause and offer little rationale for the claim to a "solution". The motivation for this dissertation is to understand the cause of these mismatches so it is then possible to address each of them in an appropriate way. Problem themes are introduced as a way to make sense of impedance mismatch. Such problems are not independent Relationships between problem themes demonstrate the complex nature of impedance mismatch and they are used to identify three problems of particular significance. A structure to existing characterisations of impedance mismatch is identified and developed in order to organise the characterisations in a meaningful and useful way. This structure, based on four levels of abstraction, forms the foundation for a new framework. The framework recognises a separation of concerns between a program and a database across levels of abstraction. At each level is observed a particular kind of impedance mismatch. Through a dialogue about a correspondence at each level it is possible to understand and address each kind of mismatch in a structured and consistent way. A technique based on equivalence is introduced in support of a dialogue. The validity of the framework is demonstrated by identifying the cause of some significant mismatches. Across all the levels of the framework are explored both the cause of each mismatch and the effect of a solution. A four-stage process is described in support of an exploration and to inform others in the use of the framework. An option for change is linked to a conceptual problem not one of implementation and the fidelity and integrity of an existing solution is improved in a way that can be generalised for other solutions. New insights are also provided into the consequences of one solution. Understanding cause and effect in this level of detail is not available using an alternative framework described in the literature. However despite the improved understanding of an impedance mismatch and the consequences of a solution there is a limit to what can be achieved using the framework.

Abstract:
In the planning stage of web and software development, it is important to select the right tool for the job. When selecting the database to use, relational databases like MySQL is a popular choice. However, relational databases suffer by object-relational impedance mismatch. In this work we will explore the response time of relational and object-oriented databases and the overhead of ORM frameworks. This will be done by creating a web application that receives data about flights and airports from a client, which measures the response time of the databases and the entire request. It was found that MySQL has the lowest response time, while the ORM framework Hibernate adds an overhead on some of the tests while performing similar to MySQL. Db4o had the highest response time in a majority of the tests. In future works, this study could be extended by other tests or by other type of databases.

Abstract:
O paradigma da orientação a objetos esta se tomando a abordagem preferida para construção de sistemas em ambiente de banco de dados. Por outro lado, a tecnologia relacional e amplamente adotada para gerenciar dados corporativos. Os bancos de dados relacionais tornaram-se o padrão no armazenamento de dados para aplicações de processamento de transações on-line (OLTP). Estas tendências estão motivando a necessidade de construção de aplicações orientadas a objetos que acessem banco de dados relacionais. 0 uso de conceitos orientado a objetos, como herança, permitem uma modelagem !Dais adequada e uma melhor implementação da aplicação baseada em sistema de banco de dados orientado a objetos. Entretanto, os resultados do projeto orientado a objetos, podem também ser aplicados em sistemas clássicos de banco de dados. 0 trabalho apresenta o uso de padrões de projeto na construção de una arquitetura de um framework que auxilie o mapeamento de uma aplicação 00 a um SGBD relacional. Esta arquitetura segue a abordagem de persistência de objetos baseada em gateways, que é uma camada de software inserida entre o sistema gerenciador de banco de dados e a aplicação orientada a objetos, cujo o objetivo é dar suporte a um modelo de programação de aplicações 00. A característica principal desta arquitetura é a separação clara das classes que tratam da base de dados em relação as classes que tratam do domínio do problema da aplicação. Esta divisão de responsabilidades permite a substituição das classes referentes a base de dados por outras, permitindo a migração da aplicação entre bases de dados diferentes. São apresentados neste trabalho, formas de mapeamentos de esquemas orientados a objetos para esquemas relacionais. Estes mapeamentos acontecem do modelo 00 para o modelo relacional. E importante salientar, que a arquitetura que esta sendo proposta, não vai impedir que aplicações estruturadas deixem ter acesso a base de dados relacional mapeada, pois esta abordagem foi escolhida para permitir que novas aplicações 00 tenham acesso a base de dados relacionais já existentes. Como a implementação deste trabalho segue a abordagem de gateway, são apresentados os conceitos de orientação objetos, e como estes serão suportados na arquitetura, ou seja, o que o gateway devera implementar.
The paradigm of the object-oriented is becoming the approach preferred for construction of systems in database environment. On the other hand, the technology relational is adopted thoroughly for management corporate data. The relational databases they became the pattern in the storage of data for applications of processing of transactions on-line (OLTP). These tendencies are motivating the need of construction of applications object-oriented that acessem relational databases. The way of using object-oriented conception, how inheritance, to make possible the better modeling and implementation based in object-oriented database systems. Therefore, the objetc-oriented design results, also is possible to application in classics database systems. The work presents the use of project patterns in the construction of an architecture of a framework that aids the mapeamento of an application 00 to a SGBD relacional. This architecture follows the approach of set persistence of objects in gateways, that is a software layer inserted among the system database manager and the object-oriented application, whose the objective is to give support to a model of programming of applications 00. The main characteristic of this architecture is the clear separation of the classes that are about the database in relation to the classes that are about the domain of the problem of the application. This division of responsibilities allows the substitution of the referring classes the database for other, allowing the migration of the application among different databases. They are presented in this work, forms of mapping the object-oriented model for relational model. These mappings happens of the model 00 for the model relational. It is important to point out, that the architecture that it is being proposed, won't impede that structured applications let to have access to the relational database, because this approach was chosen to allow that new applications 00 has access the relational database already existent. As the implementation of this work follows the gateway approach, the concepts of object-oriented are presented, and as these they will be supported in the architecture, that is to say, which the gateway should implement.

Abstract:
När man kombinerar ett objektorienterat programmeringsspråk och en relationsdatabas uppstår en del problem för utvecklare eftersom objektorienterade programmeringsspråk och relationsdatabaser har olika fokus, objektorienterade programmeringsspråk fokuserar på att avbilda verkliga objekt och relationsdatabaser fokuserar på data. De problem som uppstår kallas med ett samlingsnamn för object-relational mismatch. Det finns flertalet ramverk för att hantera dessa problem. Ett av dem är Entity Framework.Syftet med detta projekt var att utvärdera hur utvecklare tycker att Entity Framework fungerar för att lösa problematiken runt object-relational mismatch, hur det är för utvecklare att lära sig använda Entity Framework samt hur tillgången på inlärningsmaterial är.Under vår studie har vi lärt oss använda Entity Framework samtidigt som vi gjort en studie av tillgången på inlärningsmaterial. Vi har också byggt om en applikation så att den använder Entity Framework. Vi har jämfört den ombyggda applikationen med den gamla applikationen för att kunna se vilken skillnad som Entity Framework bidrog till.Vi kom fram till att Entity Framework hanterar object-relational mismatch på ett bra sätt som bland annat gör att utvecklingsprocessen kortas ner då inte lika mycket kod behöver skrivas. Utvecklare med tidigare kunskaper i .NET-programmering upplever att det är lätt att lära sig Entity Framework. Att det upplevs lätt att lära sig Entity Framework hänger förmodligen ihop med att tillgången på inlärningsmaterial är god.

Abstract:
Este trabalho apresenta o desenvolvimento de um Framework de persistência que utiliza banco de dados objeto-relacional como mecanismo de persistência. Tendo por objetivo usar os conceitos de orientação a objetos descritos na norma SQL:2008, conceitos como: objeto (atributos e métodos), herança, agregação, composição, referências (REF) e estruturas multivaloradas (arrays e multiset). Para tanto se desenvolveu e formalizou (XSD) um arquivo XML que representa um esquema de objetos através da norma SQL:2008. Da mesma forma definiu-se um conjunto de anotações Java, com o intuito de facilitar a utilização e configuração do Framework, o qual é chamado de O-ODBM (Object Object-Relational Database Management).
Persistent Frameworks have been used to aid developers, managing all access to DBMS. This kind of tool maps objects from OO applications to relational databases. Besides, allow developers to persist objects without solid knowledge about DBMSs and specific languages, making better the developers productivity, mainly when different DBMS is used. On the other hands, since 1999 the SQL specification has introduced new features to manipulate objects in relational databases which since then has been called Object-Relational Database (ORDB). At present, many DBMS offer resources to manipulate objects in database, but the most of the application developers just map class to relations tables, failing to exploit the strength of O-R model. The lack of the tools that aid the project of database contributes to this situation. Considering the vantages of use of the persistent frameworks and the ORDBs, this article introduces the O-ODM (Object-Object Database Mapping) a persistent framework for relational object databases.

After analysis of object-relational mapping framework (further – ORM) principles and features of existing ORM frameworks a model is suggested, that allows to implement ORM by utilizing MVP principles in a way that retains major portion of both approach pros and is perfect for transitioning existing relational structures to object-oriented. Further, project and implementation of prototype framework, that uses the following principles and suggested model, is described and utilized as for implementing imaginary domain ORM mapping example application.

Abstract:
This diploma work deals with design and implementation of the database neutral object-relational (OR) layer in C++ language over inherited database. The goal is to create the layer to encase the access to database from the application layer. Suggested layer will stem from the object-relation mapping technology, which is currently available for many object-programming language, such as C#, Java or Visual Basic. The work consists of three main parts. The forepart is focused on clearing object-relation mapping technology. It briefly overviews differences in capabilities and levels of implementation of various approaches. The next part describes significant properties of databases considered as back-ends for data storage in the project. The aim of this part is to present enough information to support database neutral design of the OR layer. The rest of the document deals with design and implementation of OR layer for the considered environment followed by the summarization of results and overall evaluational.

Abstract:
Denna uppsats mäter och jämför prestanda mellan en objektorienterad databas och en relationsdatabas. Uppsatsen bygger på en utredande karaktär utifrån vår hypotes och vårt intresse att testa den.Hypotesen bygger på problematiken omkring mängden kod utvecklaren måste skriva för att kunna koppla ihop applikation med databas. En större mängd skriven kod som utvecklaren måste skriva borde göra att prestanda och svarstider blir långsammare. Därför ville vi undersöka om verktyg som medför en mindre mängd skriven kod kan förbättra prestandan och ge snabbare svarstider. Vi valde att testa vår hypotes mellan ADO. NET relationsdatabas och ADO. NET Entity Framework objektorienterade databas då ADO. NET genererar större mängd kod och Entity Framework innehåller verktyg som i sin tur genererar mindre mängd kod. För att kunna mäta och jämföra prestandan utvecklades en mindre kundapplikation kopplad med respektive ramverks databasmodell där båda använder sig av samma databas. Genom att mäta prestandan har vi kunnat jämföra de olika modellerna och då även kunnat se vilka fördelar och nackdelar respektive modell genererat. Vi har även mätt antal kodrader och diskuterat hur det påverkar kostnaden av systemutvecklingen samt underhållbarheten för applikationen. Det som framförallt framkom var att relationsdatabasen resulterade i en något snabbare prestanda mätt i millisekunder trots att antal kodrader blev fler jämfört med en objektorienterad databas. Den objektorienterade databasen resulterade i något sämre prestanda men med färre antal skrivna kodrader. Det medför att den kräver mindre underhåll i koden vid förvaltning av den nya applikationen. Det innebär även att tiden vid utveckling för den vane programmeraren minskar med cirka 50 % och därmed sjunker även utvecklingskostnaden, under förutsättning att en något långsammare prestanda kan accepteras.

Abstract:
This article focuses on the use of probabilistic context-free grammars (PCFGs) in natural language processing involving a large-scale natural language parsing task. It describes detailed, highly-structured Bayesian modelling in which model dimension and complexity responds naturally to observed data. The framework, termed hierarchical Dirichlet process probabilistic context-free grammar (HDP-PCFG), involves structured hierarchical Dirichlet process modelling and customized model fitting via variational methods to address the problem of syntactic parsing and the underlying problems of grammar induction and grammar refinement. The central object of study is the parse tree, which can be used to describe a substantial amount of the syntactic structure and relational semantics of natural language sentences. The article first provides an overview of the formal probabilistic specification of the HDP-PCFG, algorithms for posterior inference under the HDP-PCFG, and experiments on grammar learning run on the Wall Street Journal portion of the Penn Treebank.

Abstract:
The Web is a crucial means for the dissemination of touristic information. However, most touristic information resources are stored directly in Web pages or in relational databases that are accessible through ad-hoc Web applications, and the use of automated processes to search, extract and interpret information can hardly be implemented. The Semantic Web technologies, aiming at representing the background knowledge about Web resources in a computational way, can be an important contribution to the development of such automated processes. This chapter introduces the concept of touristic object, giving special attention to the representation of temporal, spatial, and thematic knowledge. It also proposes a three-layered architecture for the representation of touristic objects in the Web. The central part is the domain layer, defining a Semantic Model for Tourism (SeMoT) to describe concepts, relationships, and constraints using ontologies. The data layer supports the mapping of touristic information in relational databases into Resource Description Framework (RDF) virtual graphs following the SeMoT specification. The application layer deals with the integration of information from different data sources into a unified knowledge model, offering a common vocabulary to describe touristic information resources. Finally, we also show how to use this framework for planning touristic itineraries.

Abstract:
To illuminate Bechdel’s inchoate kinship, this chapter turns to Are You My Mother?. Bechdel refuses to position Are You My Mother? as an Oedipal rival or heteronormative complement to Fun Home. In fact, neither text is compositionally “finished” within the narrative present of Are You My Mother?. Throughout the memoir, Bechdel struggles with articulating a framework for her life writing that does not recapitulate heteronormative logics of similitude based on sexual difference or Oedipal plots of exclusivity, which demand the substitution of the mother by another love object. This chapter contends that Bechdel turns to relational psychoanalysis, and D.W. Winnicott in particular, to develop a queerer narrative for kinship; in this narrative, the mother is not a taboo love object but an object to be used, played with, even affectively assaulted with anger and disappointment. Through this “mutual cathexis,” Bechdel is ultimately able to forge a relation with her mother that is not defined by their absolute similitude or radical difference. But more importantly, Are You My Mother? figures a queerer narrative for the psychoanalytic narration of kinship itself—a narrative in which the child’s and parent’s stories can exist in productive tension, even opposition, without being legitimated by or finally resolved in an external reality.

Abstract:
While some information modeling approaches (e.g., the Relational Model and Object-Role Modeling) are typically formalized using first-order logic, other approaches to information modeling include support for higher-order types. There appear to be three main reasons for requiring higher-order types: (1) to permit instances of categorization types to be types themselves (e.g., the Unified Modeling Language introduced power types for this purpose); (2) to directly support quantification over sets and general concepts; (3) to specify business rules that cross levels/meta levels (or ignore level distinctions) in the same model. As the move to higher-order logic may add considerable complexity to the task of formalizing and implementing a modeling approach, it is worth investigating whether the same practical modeling objectives can be met while staying within a first-order framework. This chapter examines some key issues involved, suggests techniques for retaining a first-order formalization, and makes some suggestions for adopting a higher-order semantics.

Abstract:
Content-centric storage represents an approach for handling large amounts of data. It is one of the innovations pursued by the VISION Cloud project. The goal of the VISION Cloud project is the development of an industry grade storage system using cloud technology. The envisaged use of the VISION Cloud involves the storage and management of millions of data items, potentially several hundreds of terabytes in size. On the one hand, the technical foundations must be capable of efficiently storing such an amount of data. On the other hand, the VISION Cloud must provide adequate means of an API for allowing the efficient navigation, search, and access for the right data item in this storage. For the latter purpose, VISION Cloud provides a data access layer, which is called “Content Centric Interface.” Applications can use this data access layer for accessing the VISION Cloud storage from a content-centric point of view, abstracted from actual storage representation. The content centric interface is different from existing cloud storage interfaces and is similar, from an architectural point of view, to object relational mapping frameworks for traditional applications with relational database systems.

Abstract:
Users interact with a database system through a set of database languages and this makes designing database languages a very challenging task to a computer software engineer. A set of well-defined database languages must be easy to learn, easy to understand and powerful enough to capture semantic of a problem domain. This paper discusses design issues of a proposed database language, namely Extended Object Language or EOL for short, for an Extolware Persistent Object framework (Lim & Lee, 1997, 1998, 1999, 2001, 2002a, 2002b, 2002c) that provide wrapping services for relational database systems and multidimensional database systems (DataPro, 1996; IBM Corp., 2001; Informix Software Inc., 2001a, 2001b). This research examines SQL3 (Fortier, 1999) and ODL/OQL (Cattell & Barry, 1999) with an overview of their language constructs and operators that support object-oriented requirements as stated in Object Data Management Group (ODMG) object model. Next, a discussion on the Extended Object Language (EOL) and its language constructs are examined. This is followed by a close examination of new database operators and constructs introduced into EOL. A design overview and evaluation of these database languages are examined. A summary on these languages is presented at the end of the paper with conclusion and further research plans.

Abstract:
Abstract This paper gives an overview of an integrated and intelligent database system for a plant engineering framework. We have integrated existing two-dimensional (2D) CAD systems, a three-dimensional (3D) CAD system, and a relational database system which stores engineering information such as design conditions, maintenance histories, and inherent properties. By integrating these systems, the infrastructure for concurrent engineering has been realized. As for design knowledge, we treat object-oriented programming as a useful knowledge representation method. We analyze the plant structure and functional requirements of the system, and then represented them by using the hierarchical Class structure. Design knowledge accompanies the Class, so we represent it using Method. As a design automation system, we develop an automated design check system. This is implemented by using the Common Lisp Object System. These systems are the main parts of the plant engineering framework, and are utilized in the practical design. We intend to develop a mechanical/electronic design framework using the same approach.

Full text
Abstract:
Relational Geometric Synthesis (RGS) is a new logical framework for building up precise definitions of complex geometric models from point! , curves, surfaces and solids. RGS achieves unprecedented design flexibility by supporting a rich, variety of useful curve and surface entities. During the design process, many qualitative and quantitative relationships between elementary objects may be captured and retained, such that they can be utilized for automatically updating the complete model geometry following changes in the sha Je or location of an underlying object. Capture of relationships enables many new possibilities for parametric variations and optimization. Examples are given of many potential applications in sailing: yacht design: hull designs; deck and cabin models; interior partitioning and planning; keel model with bulbs and winglets; hull and keel paneling for flow analysis; plating layout for metal hulls; mast and rigging models; white sails and spinnakers.

Abstract:
When a dataset is not fully specified and can represent many possible worlds, one commonly answers queries by computing certain answers to them. A natural way of defining certainty is to say that an answer is certain if it is consistent with query answers in all possible worlds, and is furthermore the most informative answer with this property. However, the existence and complexity of such answers is not yet well understood even for relational databases. Thus in applications one tends to use different notions, essentially the intersection of query answers in possible worlds. However, justification of such notions has long been questioned. This leads to two problems: are certain answers based on informativeness feasible in applications? and can a clean justification be provided for intersection-based notions? Our goal is to answer both. For the former, we show that such answers may not exist, or be very large, even in simple cases of querying incomplete data. For the latter, we add the concept of explanations to the notion of informativeness: it shows not only that one object is more informative than the other, but also says why this is so. This leads to a modified notion of certainty: explainable certain answers. We present a general framework for reasoning about them, and show that for open and closed world relational databases, they are precisely the common intersection-based notions of certainty.

Abstract:
Abstract Defect prevention is particularly critical in operations such as aircraft assembly or service. Failure Modes and Effects Analysis (FMEA) procedures have been deployed manually for many years. However, the manual procedures fail to utilize capability to build intelligence into inspection processes that can facilitate elimination of human error. In this work, we introduce an artificial intelligence (AI)-based concept that can iteratively learn to assure zero defects from a given inspection process. This work introduces a schema that can serve as a knowledge management framework in a relational database for instantiation with inspection process information and data from a detection system. A companion algorithm is presented for the case of a wiring harness bracket installation in a fuselage. The schema and algorithm analyze and assess potential defects posed by Foreign Object Debris (FOD) in parallel to the assembly inspection. A closed loop of logic was introduced to enable anomaly detection by this algorithm to assure zero defects.
