Database systems are used to manage persistent data. With the
extension of database technologies to complex application
domains it became obvious that classical technology is not
sufficient to fulfil requirements from these applications like
high performance, parallelization, distribution versioning,
support for work flow, support for multi-media data. Beside
the technical relevance, to develop a broad range of data
management functionality, an economical relevance appeared in
order to meet demands like high quality of information, reducing
costs on development and maintenance of database systems
and protecting older investments in legacy databases.
