The institution develops a unique master data model, which standardizes the definition of the core objects and relationships (e.g. persons, employers, enrolment periods, benefits). A corresponding ICT-based master data system fosters the consistency of such information.

The master data model should be of a highly stable specification covering information items used in most of the social programmes. The model can be viewed as the intersection of the sets of information items used in the social programmes. On the other hand, objects associated with specific programmes and their operations should not be included in the model (e.g. benefit payment information, variants on benefits).

The implementation of a master data model and system is addressed in a specific section of this set of Guidelines.
