A semantics-based methodology for integrated computer-aided distributed database design
H.-M.C. Garcia, Olivia R. Liu Sheng · 1992
Presents an integrated semantics-based methodology and an architectural framework for an effective computer-aided DDB design system called Auto-DDB. Auto-DDB facilitates the entire distributed database (DDB) design life cycle (e.g. from requirement specification to allocation schema generation). The design methodology which underlies the construction of Auto-DDB is based on a semantic data model, SEER (synthesized extended entity relationship model), and a transaction model, DTS (distributed transaction scheme). Design heuristic rules rooted in database theories are associated with SEER and DTS constructs for Auto-DDB to automatically transform the application semantics that have been acquired into logical and fragmentation schemata with improved structure to facilitate allocation design.>
