Maintaining transaction consistency in multidatabases using quasi serializable executions
Weimin Du, Ahmed K. Elmagarmid, W. Kim · 2002
The problem of maintaining transaction consistency in MDBSs (multidatabase systems) using quasi-realizable executions is addressed. The aspects of transaction consistency that can be effectively maintained by quasi-serializable executions are identified. A technique for preventing possible violation of those aspects of transaction consistency that are not ensured by quasi-serializable executions is proposed.>
