An Efficient Transaction Model and its Commit Method

摘要：

The traditional transaction model and commit method cannot meet the requirement of engineering design tasks which possess the properties of long duration, cooperation, heuristic, distribution, etc. Aimed at the properties of engineering design tasks, this paper presents a hierarchy transaction model with semantic properties (called HTMSP). The HTMSP adopts tree hierarchy structure and integrates semantic properties of transactions. At the same time, the HTMSP relaxes the isolation property of transactions by allowing uncommitted transactions to lend their holding data. On the basis of it, the double-tier commit method (called DTC), which can guarantee consistent data manipulation, is proposed. The DTC synthesizes the semantic properties of transactions and solves the inconsistent cases, which can be caused by reason of relaxing the isolation property.
