Exporting Database Functionality — The CONCERT Way

Abstract

In order to extend database technology beyond traditional applications a new paradigm called "exporting database functionality" as a radical departure from traditional thinking has been proposed in research and development. Traditionally, all data is loaded into and owned by the database, whereas according to the new paradigm data may reside outside the database in external repositories or archives. Nevertheless, database functionality, such as query processing, indexing, and transaction management, is provided. In this paper we report on the CONCERT project that exports physical database design for advanced applications, and we discuss the consequences for transaction management, that becomes an important coordination task in CONCERT. 1 Introduction Todays Database Management Systems (DBMS) make the implicit assumption that their services are provided only to data stored inside the database. All data has to be imported into and being "owned" by the DBMS in a format determined by the ...
