SFgate 5.0

SFgate and Heterogeneous Databases - Demo

SFgate 5.0 is able to handle heterogeneous WAIS databases. Knowing the database schemas of the WAIS databases to query it is able to take a query and map the attributes within the query onto the attributes within the databases. The user can take any attribute of the predefined attribute lattice to formulate his query.

To get an idea of what happens take a look at the three databases with bibliographic references below and the related information!

Select Databases

bibdb [database schema]
