Design of Single Relation Query Oriented ODBC Interfacewith Semantic Cache
面向单表查询的具有语义缓存功能的ODBC接口设计*

Analyses the disadvantage and the negative effects of the original PsqlODBC which doesn't use cache,and then brings semantic cache technology into PsqlODBC,which effectively utilizes the compute and storage resources of the client,reduces the workload at the database server,cuts down the query response time,and increases the throughput of system.Presents an design of single relation query oriented ODBC interface with semantic cache in terms of four aspects,i.e.the contents of the semantic cache,the relation of the query results and semantic cache results,the pick-up of the query results and the data consistency of semantic cache.
