Domain Data Model Development

A data model describes the structure of the data within a given domain and, by implication, the underlying structure of that domain itself. A data model should specify a specific grammar for a dedicated artificial language for the domain. In addition, a data model represents classes of entities (kinds of things) about which an organization wishes to retain information, the attributes of that information, and often implicit relationships among those entities as well as relationships among those attributes. The model describes the organization of the data to some extent irrespective of how data might be represented in a computer system. Data models commonly used in SDSS describe how to organize data using a database management system or other data management technology. Such a data model could describe relational tables and columns or object-oriented classes and attributes.

Editor's Notes

Karen Kemp: The data model wouldn’t be developed until the domain of the problem is specified. So its development would be determined both by the what will be done in the assessment of the current state and the methods to be used in the design and evaluation stages. In fact, a data model designed to assess the current state might be quite different from one designed during the same decision process for the design and evaluation stages. So this step may be repeated.
