摘要: A heterogeneous distributed database system (HDDBS) is a which integrates preexisting systems to support global applications accessing more than one database. The difficulties and general approaches of concurrency control in HDDBSs are studied. In particular, the author discusses maintaining serializability HDDBSs. need for new strategies established, counterexamples existing algorithms given. An assumption usually made addressing multidatabase that element databases autonomous. meaning autonomy its effects on designing addressed. It goal this study motivate other researchers realize correctness criteria by can be validated. >
