Several DataBase (DB) applications are temporal of nature and require a special treatment. In particular, in the field of Concurrency Control (CC) which takes new dimensions when applied to Temporal DB (TDB). The CC algorithms proposed for TDB have tried to find solutions for the CC to improve their performances. Especially, they have tried, by benefiting from the characteristics of the TDB, to decrease the degree of conflict and this by the use of ? priori knowledge or the reduction of the granule sizes. But these algorithms have not reached the fixed objectives. To contribute to the edification of a CC component suitable for TDB, the authors propose in this paper a complete study of access concurrency control in TDB.
