Driven by the strong need, fast prototyping technology for customize FPGAs, especially semi-custom design approaches, has been insensitively researched in recent years. As such, development cycles of custom FPGAs can be comparable to modern ASIC

Modeling Data Warehouse Schema Evolution over Extended Hierarchy Semantics,hen use the constraints to maintain integrity when schema evolution operators are applied. This paper contributes a formalism for representing data warehouse schemas and determining the validity of schema evolution operators applied to a schema. We describe a software tool that allows for visualizat

Ontology-Driven Conceptual Design of ETL Processes Using Graph Transformations, graph transformation rules, the choice and applicability of which are determined by the semantics of the data with respect to an attached domain ontology. Finally, we present our experimental findings that demonstrate the applicability of our approach.
