[Documentation and quality control].

Documentation and quality control in hospitals are not only required due to legal obligations, but should be a representation, how physicians see themselves. The fast changes in medical treatment procedures makes adequate techniques of information management indisposable. In the past data analysis in hospitals was characterized by a too strong restriction in variables under study, and a too sharp project orientation with the consequences, that many tasks had to be done repeatedly and an overview on the whole situation wasn't achieved either. So in recording postoperative wound sepsis many separate aspects have to be taken into consideration and microbiological results have to be stored in a way, that differentiation over time is possible. For medical data management a time oriented database structure is therefore advisable and more adequate than a relational one.
