Original Kurzfassung:
The provision of context-aware services in terms of the
anytime/anywhere/anymedia paradigm requires the consideration of certain
context properties in terms of time, location, device, or simply the user’s
preferences. The specific characteristics of context, comprising among others
large amounts of data, frequent and concurrent updates, and different, often
heterogeneous sources and XML schemata demand for an efficient
management of context data. Relational databases seem to be a promising key
technology for the efficient storage, retrieval, and processing of XML-based
context data. This is not least since relational databases allow to seamlessly
combine context data with already existing legacy data, hereby constituting a
major advantage compared with native XML databases or object-oriented
databases. This paper focuses on a generic approach for mediating between
XML-based context and context stored in relational databases. With this,
maintainability and changeability of context data is enhanced, since the
mapping knowledge is not hard-coded but rather reified within a meta schema.
The meta schema allows to automatically compose context data out of the
relational database when requested and decompose them when they have to be
stored.
