Amazon.com description: Product Description: This collection of original contributions by leading database professionals illuminates the technical issues involved in the transition to new database technologies, and in making installed database systems and file systems interoperable. In its survey of emerging database technologies, the book describes two database challenges, and suggests solutions for them. One challenge is to move from current database technologies to a variety of post-relational technologies: object-oriented database systems, systems that accommodate functional extensions, and systems that support temporal, spatial, and multimedia data management. A second challenge is to provide interoperability of database systems and file systems currently installed worldwide. While database vendors now offer gateways allowing relational database systems to interact with non-relational systems, multidatabase systems soon will allow users to access a range of systems in a single, uniform, database language.Modern Database Systems shows how emerging database applications require new and innovative database systems, defining the issues involved, proposing solutions, and suggesting directions fro future research and development. Database designers, developers, and users will find both a comprehensive picture of the most current technologies and a preview of what is to come. 0201590980B04062001
