** Content Requirements Functional Nonfunctional Design Overview Architectural components Application flow Technologies

** Functional requirements The system must provide: A JDBC driver that any client application can use for accessing various data sources ( e.g. RDF datasource, MySql...) A Manager Web Interface (MWI) which can be used to limit the data available through the JDBC driver. A MWI user will be able to construct relational tables based on the data from a given data source and in that way provide only the data he wants through the JDBC driver. Complete transparency to the end application that is using it.

** Non-functional requirements System response time < 10 seconds Easy to use Multiple concurent users support
