限定符和类型	类和说明
static interface	Databases.Benchmarkable<R>
static interface	Databases.DatabaseInvoke<T,R> Represents a logic of data process, it will provide the connection and sql executor of database, and the concrete logic will be ignored the behavior about connection.
static interface	Databases.TransactionalExecutor<R> Represents logic will be executed in the transaction(There's only one connection of database)
