Design and Implementation of TempDB

Generally speaking, implementation techniques of temporal database management systems are lagging behind the corresponding theoretical achievements. In this chapter, the design and implementation details of a temporal data processing prototype system, TempDB, are presented. TempDB improves the grammar of ATSQL2 and corresponding temporal integrity constraints. The temporal index with Now binding function is introduced to improve the query performance. TempDB combines and applies relevant theories and development methods of temporal databases. TempDB also accumulates relevant development experience for future implementation of temporal database.
