If HIKARICP is available, we will use it. If Commons DBCP is available, we will use it, but it is not recommended in the production environment. Finally, if

integrity constraints that are defined on the data. Isolation (Isolation): There may be multiple transactions executing concurrently in the same environment, and each transaction should be performed independently. The effect of serially executing a series of transactions should be the same as executing them concurrently. This requires two things: During the execution of a transaction, the intermediate (possibly inconsistent) state of the data should not be exposed to all other transactions. T
