OLAP (On-line Analytical Processing) online analytical processing, also known as transaction-oriented processing, is characterized by the fact that the user data received by the foreground can be transferred immediately to the computing center for processing and the processing results are given in a very short period of time. is one of the ways to quickly respond to user actions.OLTP (on-line Transaction processing) online transaction processing, which enables analysts to quickly, consistently a

OLTP performance adjustment and optimization-conclusion According to the waterfall model of the software life cycle, the performance of an application has been qualitative in its design stage. If you think of optimization only after the application development is complete, you can only cure the problem. In the case of serious performance problems, you even need to re-launch the entire software. When a software system has been launched for operation an
