Research on Database Application Performance Optimization Method

Optimization of database systems for the normal operation of the whole system plays a vital role, but it is a very complex task.The final decides the database performance database availability.A database can be up and running, but if you want to take a long time to return results, then their use will be limited.From the user's point of view, if the actual throughput for a given period of time in the database is high, the actual performance of the database is higher.On the other hand, the poor performance of the database to run a large complex query seems to stop at some point, like a database does not exist, so was anxious to let the user.Therefore it emphasizes optimization is very important.
