Abstract:

The goal of this work is to present an advanced query processing algorithm formulated and developed in support of heterogeneous distributed database management systems. Heterogeneous distributed database management systems view the integrated data through an uniform global schema. The query processing algorithm described here produces an inexpensive strategy for a query expressed over the global schema. The research addresses the following aspects of query processing: (1) Formulation of a low level query language to express the fundamental heterogeneous database operations; (2) Translation of

Abstract:

The thesis investigates the possibility to create software that can synchronize heterogeneous data from generic databases through the Internet. To further enhance the conclusion, we implement a prototype that fetches data from numerous source system databases, and stores the data in another location, more accessible for processing. To achieve that, previous work with topics related to the area was inspected and analyzed. Based on the investigation, the implemented prototype uses a client-server approach which communicates with a REST-like design using JSON-strings and HTTP. This thesis and the

Abstract:

Autonomy of operations combined with decentralised management of data has given rise to a number of heterogeneous databases or information systems within an enterprise. These systems are often incompatible in structure as well as content and hence difficult to integrate. This thesis investigates the problem of heterogeneous database integration, in order to meet the increasing demand for obtaining meaningful information from multiple databases without disturbing local autonomy. In spite of heterogeneity, the unity of overall purpose within a common application domain, nevertheless, provides

Today, databases have become an integral part of information systems. In the past two decades, we have seen different database systems being developed independently and used in different applications domains. Today's interconnected networks and advanced applications, such as data warehousing, data mining & knowledge discovery and intelligent data access to information on the Web, have created a need for integrated access to such heterogeneous, autonomous, distributed database systems. Heterogeneous/multidatabase research has focused on this issue resulting in many different approaches. However

Abstract:

In today's networked world, information is widely distributed across many independent databases in heterogeneous formats. Integrating such information is a difficult task and has been adressed by several projects. However, previous integration solutions, such as the EVE-Project, have several shortcomings. Database contents and structure change frequently, and users often have incomplete information about the data content and structure of the databases they use. When information from several such insufficiently described sources is to be extracted and integrated, two problems have to be solved:

Critical to semantic integration of heterogeneous data sources, determining the semantic correspondences among the data sources is a very complex and resource-consuming task and demands automated support.

Semantic correspondences on the two levels are identified alternately and incrementally in an iterative procedure.

Abstract:

Information sharing among databases requires the development of techniques for accessing data from multiple heterogeneous databases. One approach to providing interoperability among these databases, is to define one or more schemas representing a coherent view of the underlying databases. A review of existing research on schema integration, the process of generating integrated schemas, points to the need for development of techniques for identifying objects in multiple databases that may be related. The development of efficient mechanisms for accessing heterogeneous databases is another issue

Instead, a wide variety of ways of enhancing database migrations have emerged.

Abstract:

In an increasing number of use cases, databases face the challenge of managing heterogeneous data. Heterogeneous data is characterized by a quickly evolving variety of entities without a common set of attributes. These entities do not show enough regularity to be captured in a traditional database schema. A common solution is to centralize the diverse entities in a universal table. Usually, this leads to a very sparse table. Although today’s techniques allow efficient storage of sparse universal tables, query efficiency is still a problem. Queries that address only a subset of attributes have
