VerbaAlpina defines data modelling as the theoretical development of an organisation of initially unstructured data. Essentially, this is about defining so-called entities – a class of digital single objects that have a certain type and number of attributes (= properties) in common. It is only these attributes that are relevant for the content-related and functional determination of the objects. During data modelling, the relationship between the different entities is defined as well.<br>
Data modelling must be distinguished from data structuring and data format. Data structuring is the concrete application of the theoretical data model to a set of data. Its result is a structured representation of the data in the form of one or multiple tables. A structured set of data can, in turn, be displayed as different data formats (e.g., as tables = relational data format, XML-format etc.) while often times, a transformation from one into another format is possible.<br>
