Abstract

"Modularity is the key to achieving the aims of reusability and extensibility" stated Bertrand Meyer in 1988. Relational database systems lack proper abilities supporting a modular design. There are only flat schemata and no encapsulation. The SQL:1999 standard has integrated object-oriented concepts into the relational model leading to so-called ORDBMSs. User-defined types and routines, server modules etc. introduce a new complexity but also embody new possibilities for a modular design. In this paper, we discuss how these concepts can facilitate the development of modular, ORDBMS-based applications.
