Computer Science and Engineering Division and published by . This book was released on 1994 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "It has been shown that the database schemata often experience considerable changes during the development and initial use phases of database systems for advanced applications, such as automated manufacturing and computer-aided design. An automated schema evolution system can significantly reduce the amount of work and potential errors related to schema changes. Although schema evolution for non-real-time databases was the subject of some previous research, its impact on real- time database systems remains unexplored. Since these advanced applications typically utilize object-oriented models to handle complex data types and there exists no agreed-upon real-time object model that can be used as foundation to define a schema evolution framework, we first design a conceptual real-time object-oriented data model, called ROMPP. It captures the key characteristics of real-time applications, namely, timing constraints and performance polymorphism. It uses specialization dimensions to model timing specifications and letter class hierarchies to capture performance polymorphism. We then re-evaluate previous (non-real- time) schema evolution support in the context of real-time databases, which results in several modifications to the semantics of schema changes and to the needs of schema change resolution rules and schema invariants. Furthermore, we expand the schema change framework with new constructs -- including new schema change operators, new resolution rules, and new invariants -- for handling additional features of the real-time object model."

Download or read book Aspect Oriented Database Systems written by Awais Rashid and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, a set of new software development techniques – termed Aspect-Oriented Software Development (AOSD) – has become available that aims to support modularisation of systemic properties (also referred to as crosscutting-concerns) and their subsequent composition with other parts of the system. Rashid focuses on the use of Aspect-Oriented Programming (AOP) techniques to modularise otherwise broadly scoped features in database systems like the transaction or the versioning model to improve their customisability, extensibility, and maintainability. His aim is to show how the use of AOP can transform the way we develop, use and maintain database systems. He also discusses how database systems can support AOP by providing means for storage and retrieval of aspects. Aspect-Oriented Databases Systems shows the possible synergy between AOSD and database systems and is of particular interest for researchers, graduate students and software developers in database systems and applications.

Download or read book Object Oriented Database Systems Approaches and Architectures written by Prabhu C.s.r. and published by PHI Learning Pvt. Ltd.. This book was released on 2010-11 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This well-received book, now in its third edition, is a comprehensive presentation of the fundamentals of object-oriented database systems (OODBMS). It provides extensive coverage of the different approaches to object data management, including the three major approaches--semantic database systems approach, object-oriented programming language extension approach, and the relational extension approach--as well as the various types of architectures of object-oriented database systems. The book discusses all recent developments in this field, such as the emergence of Java as the dominant object-oriented programming language--resulting in upcoming OODBMS products such as Ozone--and the provision of object-oriented database features in object-relational database systems (ORDBMS) products such as Oracle 9i and DB2. The new edition provides an extensive discussion of PostgreSQL, a popular open source object-oriented database system which has emerged as a viable alternative to expensive commercial database systems such as Oracle. The book is extensively illustrated, which enables students to develop a firm grasp of the underlying concepts. The chapter-end exercises help in testing the students' comprehension of the fundamental principles. The book is primarily meant for students of IT-related programmes having courses in database systems. Computer professionals will also find the book immensely useful.

Available in PDF, EPUB and Kindle. Book excerpt: Once a radical notion, object-oriented programming is one of today's most active research areas. It is especially well suited to the design of very large software projects involving many programmers all working on the same project. The original contributions in this book will provide researchers and students in programming languages, databases, and programming semantics with the most complete survey of the field available. Broad in scope and deep in its examination of substantive issues, the book focuses on the major topics of object-oriented languages, models of computation, mathematical models, object-oriented databases, and object-oriented environments. The object-oriented languages include Beta, the Scandinavian successor to Simula (a chapter by Bent Kristensen, whose group has had the longest experience with object-oriented programming, reveals how that experience has shaped the group's vision today); CommonObjects, a Lisp-based language with abstraction; Actors, a low-level language for concurrent modularity; and Vulcan, a Prolog-based concurrent object-oriented language. New computational models of inheritance, composite objects, block-structure layered systems, and classification are covered, and theoretical papers on functional object-oriented languages and object-oriented specification are included in the section on mathematical models. The three chapters on object-oriented databases (including David Maier's "Development and Implementation of an Object-Oriented Database Management System," which spans the programming and database worlds by integrating procedural and representational capability and the requirements of multi-user persistent storage) and the two chapters on object-oriented environments provide a representative sample of good research in these two important areas. Bruce Shriver is a researcher at IBM's Thomas J. Watson Research Center. Peter Wegner is a professor in the Department of Computer Science at Brown University. Research Directions in Object-Oriented Programmingis included in the Computer Systems series, edited by Herb Schwetman.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Schema evolution support is an important facility for object-oriented database (OODB) systems. While existing OODB systems provide for limited forms of evolution, including modification to the database schema and reorganization of affected instances, we find their support insufficient. Specific deficiencies are 1) the lack of compatibility support for old applications, and 2) the lack of ability to install arbitrary changes upon the schema and database. This paper examines the limitations of existing schemes, and offers a more general framework for specifying and reasoning about the evolution of class definitions and the adaptation of existing, persistent instances to those new definitions."
