All-inclusive and easy-to-use intuitive software which shows database performance problems in a clear way, yet is also able to precisely indicate their causes. One of the main issues in effectively providing IT services is maintenance of adequate performance levels of the system. Frequently, the only solution that many companies can offer to these problems is investment in larger, more efficient servers. Unfortunately, this does not always bring the anticipated results despite high expenditures. Optimisation of business system performance on the level of existing databases can be an effective solution to these problems. Instead of investing in hardware, performance problems can be more effectively solved by using the appropriate database optimisation at the level of the most overloaded SQL queries. To optimise a database, it is essential to locate bottlenecks and understand why they arise.
