Download or read book Upgrading Relational Databases with Objects written by Robert Vermeulen and published by Cambridge University Press. This book was released on 1997-12-13 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upgrading Relational Databases with Objects presents a clear-headed overview of how to use object-oriented (OO) technology to improve existing relational databases. This practical how-to guide starts with the basics of OO and works its way up to examples and what-if scenarios that illustrate how OO technology is, should be and should not be integrated with relational databases. It draws a keen distinction between applications that can be best performed with each technology. The book describes such object technologies as OLE and CORBA and what their impacts will be on relational database connectivity and provides a brief tutorial on relational and object concepts, it then moves on to advanced object/relational, SQL3, OO database technology and the Internet.

Download or read book Improving data quality in relational databases written by Tennyson X. Chen and published by RTI Press. This book was released on 2011-05-19 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The traditional vertical decomposition methods in relational database normalization fail to prevent common data anomalies. Although a database may be highly normalized, the quality of the data stored in this database may still deteriorate because of potential data anomalies. In this paper, we first discuss why practitioners need to further improve their databases after they apply the traditional normalization methods, because of the existence of functional entanglement, a phenomenon we defined. We outline two methods for identifying functional entanglements in a normalized database as the first step toward data quality improvement. We then analyze several practical methods for preventing common data anomalies by eliminating and restricting the effects of functional entanglements. The goal of this paper is to reveal shortcomings of the traditional database normalization methods with respect to the prevention of common data anomalies, and offer practitioners useful techniques for improving data quality.
Download or read book Fundamentals of Object Databases written by Suzanne Dietrich and published by Springer Nature. This book was released on 2022-05-31 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Object-oriented databases were originally developed as an alternative to relational database technology for the representation, storage, and access of non-traditional data forms that were increasingly found in advanced applications of database technology. After much debate regarding object-oriented versus relational database technology, object-oriented extensions were eventually incorporated into relational technology to create object-relational databases. Both object-oriented databases and object-relational databases, collectively known as object databases, provide inherent support for object features, such as object identity, classes, inheritance hierarchies, and associations between classes using object references. This monograph presents the fundamentals of object databases, with a specific focus on conceptual modeling of object database designs. After an introduction to the fundamental concepts of object-oriented data, the monograph provides a review of object-oriented conceptual modeling techniques using side-by-side Enhanced Entity Relationship diagrams and Unified Modeling Language conceptual class diagrams that feature class hierarchies with specialization constraints and object associations. These object-oriented conceptual models provide the basis for introducing case studies that illustrate the use of object features within the design of object-oriented and object-relational databases. For the object-oriented database perspective, the Object Data Management Group data definition language provides a portable, language-independent specification of an object schema, together with an SQL-like object query language. LINQ (Language INtegrated Query) is presented as a case study of an object query language together with its use in the db4o open-source object-oriented database. For the object-relational perspective, the object-relational features of the SQL standard are presented together with an accompanying case study of the object-relational features of Oracle. For completeness of coverage, an appendix provides a mapping of object-oriented conceptual designs to the relational model and its associated constraints.

Download or read book Foundation for Future Database Systems written by C. J. Date and published by Addison-Wesley Professional. This book was released on 2000 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: -- Places object databases into perspective and shows how they fit into the relational continuum. -- Includes important new relational algebra and database programming ideas, and a complete new model for database subtyping and inheritance. -- Includes a detailed review of SQL:1999 (SQL3) and the proposals of the Object Data Management Group (ODMG). Foundation for Future Database Systems: The Third Manifesto offers a comprehensive, insightful proposal for the future of object/relational database management systems. Date and Darwen present a precise, formal definition of an abstract model of data that can be used as a blueprint for designing both databases and database languages -- and as a rock-solid foundation for integrating relational and object technologies. This new Second Edition has been revised extensively, with major extensions to its inheritance model; new language proposals, and improved discussions of many key concepts. The book goes beyond formal specifications, with a detailed discussion of the rationale for each proposal. It will be essential reading for everyone with a serious interest in database technology.

Download or read book View Updating and Relational Theory written by Chris Date and published by "O'Reilly Media, Inc.". This book was released on 2013 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Views are virtual tables. That means they should be updatable, just as "real" or base tables are. In fact, view updatability isn’t just desirable, it’s crucial, for practical reasons as well as theoretical ones. But view updating has always been a controversial topic. Ever since the relational model first appeared, there has been widespread skepticism as to whether (in general) view updating is even possible. In stark contrast to this conventional wisdom, this book shows how views, just like base tables, can always be updated (so long as the updates don’t violate any integrity constraints). More generally, it shows how updating always ought to work, regardless of whether the target is a base table or a view. The proposed scheme is 100% consistent with the relational model, but rather different from the way updating works in SQL products today. This book can: Help database products improve in the future Help with a "roll your own" implementation, absent such product improvements Make you aware of the crucial role of predicates and constraints Show you how relational products are really supposed to behave Anyone with a professional interest in the relational model, relational technology, or database systems in general can benefit from this book.

Download or read book Distributed Object Architectures with CORBA written by Henry Balen and published by Cambridge University Press. This book was released on 2000-02-13 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed Object Architectures with CORBA is a guide to designing software comprised of distributed components. While it is based on OMG's Common Object Request Broker Architecture (CORBA) standard, the principles also apply to architecture built with other technology (such as Microsoft's DCOM). As ORB products evolve to incorporate new additions to CORBA, the knowledge and experience required to build stable and scalable systems is not widespread. With this volume the reader can develop the skills and knowledge that are necessary for building such systems. The book assumes a familiarity with object-oriented concepts and the basics of CORBA. Software developers who are new to building systems with CORBA-based technologies will find this a useful guide to effective development.
