SQL Server Application Mode-OLTP system Performance Analysis

The OLTP system features a large number of small transactions with high concurrency in such applications, including SELECT, INSERT, UPDATE, and DELETE. These operations are relatively simple, and the transaction time is not very long, but the required return time is very strict, basically it takes several seconds to return. It is a typical O-

The OLTP system features a large number of small transactions with high concurrency in such applications, including SELECT, INSERT, UPDATE, and DELETE. These operations are relatively simple, and the server space and transaction time will not be long, but the required return time is very strict. Basically, it takes several seconds to return.

Database applications that support production pipelines. The U.S. Server is a typical OLTP system. There are many processes in the process from raw materials to final product assembly. Each process is not complex and does not take much time. The factory must use the database application to record and monitor each process. On the assembly line, workers can scan the bar code on the product to quickly input the product processing, processing or inspection results. These input and modification processes are simple, and many operations in the database are INSERT, UPDATE, or DELETE. However, the response speed of the application is very high, and the wait time is negligible. It takes several seconds for a worker to enter a bar code. Many workers spend several seconds processing each product. If it takes him dozens of seconds, the entire pipeline will be slow. If a problem occurs in the system, it takes several minutes for the system to process a product. The pipeline will be paralyzed and the workers will be able to drink tea. At this time, the database administrator will be faced with a worried management level.

Therefore, when designing the OLTP system, you should be very careful about the Hong Kong virtual host. For example, it is absolutely necessary to avoid blocking the entire server range due to a single statement.

Pay attention to the following issues in the OLTP system.
