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
