This book was released on 2013-11-09 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Object-oriented database management systems (OODBMSs) have generated significant excitement in the database community in the last decade. This interest stems from a real need for data management support for what are called "advanced application areas" that are not well-served by relational technology. The case for object-oriented technology has been made on three fronts. First is the data modeling requirements of the new applications. Some of the more important shortcomings of the relational systems in meeting the requirements of these applications include: 1. Relational systems deal with a single object type: a relation. A relation is used to model different real-world objects, but the semantics of this association is not part of the database. Furthermore, the attributes of a relation may come only from simple and fixed data type domains (numeric, character, and, sometimes, date types). Advanced applications require explicit storage and manipulation of more abstract types (e.g., images, design documents) and the ability for the users to define their own application-specific types. Therefore, a rich type system supporting user defined abstract types is required. 2. The relational model structures data in a relatively simple and flat manner. Non traditional applications require more complex object structures with nested objects (e.g., a vehicle object containing an engine object).

Available in PDF, EPUB and Kindle. Book excerpt: Deductive databases and object-oriented databases are at the forefront of research in next-generation intelligent database systems.Object-oriented programming and design methodologies have great potential, promising to reduce the complexity of very large software systems in such domains as computer-aided design and manufacturing, integrated office information systems, and artificial intelligence. Object-oriented database systems will enhance the programmer/user productivity of such systems. Research into deductive databases is aimed at discovering efficient schemes to uniformly represent assertions and deductive rules, and to respond to highly expressive queries against the knowledge base of assertions and rules. This area of research is strongly interacting with Logic Programming which has developed in parallel, sharing Logic as a common basis. Recently, research has aimed at integrating the object-oriented paradigm and rule-based deduction to provide a single powerful framework for intelligent database systems.The aim of this book is to present research papers and technical discussions between researchers concerned with deductive databases, object-oriented databases, and their integration.

This book was released on 1992 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Database programming languages like O2, E, and O++ include the ability to iterate through a set. Nested iterators can be used to express joins. Without program analysis, such joins must be evaluated using a tuple-at-a-time nested-loops join algorithm, because otherwise program semantics may be violated. Ensuring that the program's semantics are preserved during transformation requires paying careful attention to the flow of values through the program. This thesis presents conditions under which such transformations can be applied. This thesis then shows how to use a standard transformation-based optimizer to optimize these joins

This book was released on 2012-12-06 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Object-oriented database management systems (OODBMS) are used to imple ment and maintain large object databases on persistent storage. Regardless whether the underlying database model follows the object-oriented, the rela tional or the object-relational paradigm, a key feature of any DBMS product is content based access to data sets. On the one hand this feature provides user-friendly query interfaces based on predicates to describe the desired data. On the other hand it poses challenging questions regarding DBMS design and implementation as well as the application development process on top of the DBMS. The reason for the latter is that the actual query performance depends on a technically meaningful use of access support mechanisms. In particular, if chosen and applied properly, such a mechanism speeds up the execution of predicate based queries. In the object-oriented world, such queries may involve arbitrarily complex terms referring to inheritance hierarchies and aggregation paths. These features are attractive at the application level, however, they increase the complexity of appropriate access support mechanisms which are known to be technically non-trivial in the relational world.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive collection is a survey of research in object-oriented databases, offering a substantive overview of the field, section introductions, and over 40 research papers presented in their original scope and detail. The balanced selection of articles presents a confluence of ideas from both the language and database research communities that have contributed to the object-oriented paradigm. The editors develop a general definition and model for object-oriented databases and relate significant research efforts to this framework. Further, the collection explores the fundamental notions behind object-oriented databases, semantic data models, implementation of object-oriented systems, transaction processing, interfaces, and related approaches. Research and theory are balanced by applications to CAD systems, programming environments, and office information systems.

Download or read book Query Optimization by Semantic Reasoning written by J. J. King and published by . This book was released on 1981 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of database query optimization is to select an efficient way to process a query expressed in logical terms from among the alternative ways it can be carried out in the physical database. This thesis presents a new approach to this problem, called semantic query optimization. The goal of semantic query optimization is to produce a semantically equivalent query that is less expensive to process than the original query. Semantic query optimization actually transforms the original query into a new one by means of a process of inference. The transformations are limited to those that yield a semantically equivalent query, one that is guaranteed to produce the same answer as the original query in any permitted state of the database. This guarantee is achieved because the knowledge used to transform a query is the same knowledge used to insure the semantic integrity of the data stored in the database. Thus, semantic query optimization brings together the apparently separate research areas of query processing and database integrity. The thesis formally defines transformations that preserve semantic equivalence for queries in the relational calculus. In addition, it identifies several classes of cost-reducing query transformations for relational database queries, and provides quantitative estimates of the improvements they can produce, based upon widely accepted models of query processing. The thesis also discusses the design and implementation of a system that carries out semantic query optimization for an important class of relational database queries.
