| Zusammenfassung | A general relational data model for setting up large or medium sized databases of measurement data in the field of metrology is discussed. Structuring and organization of the measurement data in vacuum metrology is considered to be an illustrating and typical example from the metrological domain. The second example describes the data model of a bio-signal database containing electro-cardiograms and clinical data of patients with cardiac diseases. The key ideas of the presented generic data models can be expressed by a separation of the relevant data objects into two groups: The first group describes the metrological area semantically by methods of measurement and by parameters of physical or technical quantities needed to define the characteristic features and the data sampled by these methods. The usage of these methods is described in the second group of data objects: Each measurement or calibration is seen as an event. It registers the deployment of a method and provides all the sampled current values of the parameters belonging to the method. The fixed current values of the parameters are organized in data-type-specific objects. They represent the data collections resulting from the measurements or calibrations. The major parts of the data model for calibrations in vacuum metrology and for bio-signals in medical physics are used to derive the reusable kernel of a template database suitable for different metrological domains. It represents the predefined and simple structure for an open-ended data model which is flexible enough to support a wide range of metrological applications. |
