What Is aData Representation Model?
The SEDRIS data representation model is more than a simple abstraction of a given data model.
Generally, a data model is the specific collection of data structures and their relationships that specify a unique instance of data for some concept or object.
However, multiple data models can be realized that describe the same object or concept. Problems in communication and interchange arise because
- different data models may reflect different perspectives on what is important about a concept
- software written to parse and process a specific data model's schema and format will not be able to process that used to realize another data model
