One of the important issues to consider when designing a new or analyzing an existing system is the design of the application. Even if the database is well designed and optimized, application design is not appropriate or a database that can cause performance problems. Practice has shown that if there is a design problem with the application, modifying these issues can improve the performance of the application better than adjusting the database configuration parameters. For example,
