Query processing in heterogeneous distributed database management systems
… and developed in support of heterogeneous distributed database management systems. Heterogeneous distributed database management systems view the integrated data through an uniform global schema. The query processing algorithm described here produces an inexpensive strategy for a query …

Performance of Concurrency Control Methods in Distributed Database Management Systems (Timestamp Ordering, Two-Phase Locking, Optimistic Scheme, Restart, Transaction Blocking)
… developed, and the performances of those CCMs in distributed database management system (DDBMS) were simulated with some care to get statistically significant results. The performances of the CCMs were then compared with respect to several measures. This study systematically investigated effects …
