The invention relates to a method of handling event recordings in a service database system. The database comprises measurement tables (MT) which include consecutive rows (Ri). A single row comprises data about a single measurement object. So that correct counter values can be recorded efficiently, the counters on the measurement table row have been duplicated, and in every recording interval the counter values of a given counter group on said row are incremented, and the counter values of another given counter group on said row are recorded according to a predefined rotation principle. In the system, measurement object-specific and measurement group-specific time stamps are maintained, on the basis of which it is tested whether the counter values are acceptable for recording. |
