![]() The challenges and tradeoffs faced by the designers of real-time database systems are quite different from those faced by the designers of general-purpose database systems. In a database, real-time means that in addition to typical logical consistency constraints, such as a constraint on a data item's value, there are constraints on when transactions execute and on the freshness' of the data transactions access. Описание: Real-time systems are defined as those for which correctness depends not only on the logical properties of the produced results, but also on the temporal properties of these results. Название: Real-Time Database and Information Systems: Research Advances The book identifies actual and potential areas of integration of OO and database technologies, current and future research directions in software methodologies, and reflections about the OO paradigm.In providing current research and relevant information about this promising and rapidly growing field of object-oriented databases and software engineering systems, this book is invaluable to research scientists, practitioners, and graduate students working in the areas of databases and software engineering. Описание: Object orientation has become a "must know" subject for managers, researchers, and software practitioners interested in the design, evolution, reuse and management of efficient software components.The book contains technical papers reflecting both theoretical and practical contributions from researchers in the field of object-oriented (OO) databases and software engineering systems. Издательство: World Scientific Publishing Название: Object-Oriented Technology For Database And Software Systems Both, approaches to extend databases with object-oriented capabilities and approaches to extend object-oriented programming languages with database features have been and are being investigated. A number of research prototypes and even some commercial systems are meanwhile available. transactions, implementation techniques, optimization, formalization, the inclusion of rules, and the integration with other systems. Though data model concepts are the decisive feature of object-oriented database systems, numerous other system aspects have to be reconsidered or allow better solutions, respectively, in this light. Structural object-orientation provides for data model mechanisms that allow the direct representation and manipulation of highly-structured entities behavioral object-orientation cares for facilities to associate arbitrary user-defined type-specific operations with data entities finally, full object-orientation tries to combine the advantages of both categories. The notion of object-orientation in database systems is thus a broader one than e.g. Object-oriented database systems have been approached with mainly two major intentions in mind, namely to better support new application areas like CAD/CAM, office automation, knowledge engineering, and to overcome the impedance mismatch between data models and programming languages. It thus gives a comprehensive overview of the latest developments in this flourishing area of current database research.
