. Ensure system security It is necessary to take the time to actively discover security issues and prevent incidents from being handled afterwards. My other article TechNet, "common SQL Server Security Problems and Solutions", lists ten of the most common security problems and solutions. In addition, do not forget to fix the system in time when detecting the vulnerability. 5. Deal with the

What do we need to do when we successfully connect to the database? we know that the operational database can be used SQL statement, SQL The statement is used to do the database additions, deletions, modifications, query operations. So we need to define a SQL statement that tells the computer what it should do. So the following statements

recommended). Locks can clog the database, so larger locks cause more blocking, but because large-grained locks require fewer locks, they can improve performance. Small-grained locks reduce congestion because they lock in less resources, thereby increasing concurrency, while a large number of locks can cause performance degradation. So the granularity of the lock is shown in the relationship between performance and concurrency 8. Figure 8: Effect of

The application of the Olite system is a Web Form program based on the. NET platform, and the database is SQL Server 2005. Its main structure is as follows: Its application end con

SQL Server database optimization solution There are many reasons for slow query speed. The following are common causes: 1. No index or no index is used (this is the most common problem of slow query and is a defect in programming) 2. Low I/O throughput, resulting in a bottleneck effect. 3. the query is not optimized because no computing column is created. 4. Insufficient memory 5. slow network speed 6. The
