Research based on database transactions

The process of using the database in order to ensure the correctness of data manipulation, we realized affairs. Transaction is a set of logical operation unit, the data transformation from one state to another state, to ensure consistency of data in the database, data manipulation should be discrete groups of logic cells, and when it all finished, Data consistency can be maintained, and when a part of this unit fails, the entire transaction should be fully considered as an error, all subsequent operations from the starting point should all fall back to the starting state. Therefore, to correct the data management services can ensure the integrity of the transaction is the basis for programming and transaction management. Based on the characteristics of database transactions, database transactions to achieve the research.
