Transaction per second

Transaction / second   Transactions per second In RDBMS, previously executed SQL commands can be either committed [by commit command to confirm], or rollback [by rollback command to cancel]; Transactions [Transaction = relational data + SQL command] occur among computers [In common, sessions' bandwidth becomes bottleneck], so that the serving-speed of the computers can be measured in a computing-unit called transaction per second;
