DTM DB Stress is a utility for stress testing the server parts of information systems and applications, as well as DBMSs and servers themselves. This tool allows you to create and configure a continuous set of requests to the server of the OLAP (query execution) and OLTP (adding, modifying and deleting data in the database) types. At the same time, the user can flexibly change both the number and the priority of this or that type of requests to a database or an application.

The program is useful for any information system developer or any QA department employee who wants to make sure the product under development can work with a large number of simultaneous connections and concurring queries and transactions. Database administrators can use this utility to evaluate the current performance of servers and to make plans about increasing processing power.

A test project consists of a set of tasks. Each task is an SQL statement that will be executed in a loop in the process of testing. Each task can be run as several copies running simultaneously in separate threads. Tasks have different properties and priority. In the last three cases those iterations that are already in process are not interrupted, but executed to an end, that is why the actual number of executed iterations may exceed the specified value or time a little.
