On Efficiently Implementing SchemaSQL on a SQL Database System (1999)
Laks Lakshmanan, Fereidoon Sadri, Subbu N. Subramanian
SchemaSQL is a recently proposed extension to SQL for enabling multi-database interoperability. Several recently identified applications for SchemaSQL, however, mainly rely on its ability to treat...
SchemaSQL -- A Language for Interoperability in Relational Multi-database Systems (1996)
Laks Lakshmanan, Fereidoon Sadri, Iyer N. Subramanian
We provide a principled extension of SQL, called SchemaSQL , that offers the capability of uniform manipulation of data and meta-data in relational multi-database systems. We develop a precise syntax...
On Semantic Query Optimization In Deductive Databases (1992)
The focus of this paper is semantic query optimization in the presence of integrity constraints (ICs) such as inclusion dependencies (INDs) and context dependencies (CDs). INDs are well known to...
