Standard Data Model

An industry standard data model, or simply standard data model, is a data model that is widely used in a particular industry. The use of standard data models makes the exchange of information easier and faster because it allows heterogeneous organizations to share an agreed vocabulary, semantics, format, and quality standard for data. Organizations may save time and expense by using pre-existing data models instead of developing them in-house, although the process of making data conform to external models can also be a hindrance.

Standards are often defined by standards bodies or technology companies.

Most models use the relational model of database management, but some use the hierarchical model, especially those used in manufacturing or those mandated by governments, such as models specified by DIN codes in Germany.

Applications

Effective standard models have developed in the banking, insurance, pharmaceutical and automotive industries. These models reflect stringent standards required in these industries for customer information gathering, customer privacy, consumer safety, or just in time manufacturing.

The most complex data models known are in military use. Consortia such as NATO tend to require strict standards for their members' equipment and supply databases. While standards for commercial software are usually open to view and implement, military data standards are often private and internal.

Issues

Standard data models usually require the translation of existing company data to fit the model's specification, which may cost more than is gained by the use of such a model. Inflexible models might not be able to capture all of the data of a given organization, or new types of data that arise as an organization or industry develops. If one organization needs to make changes to its software architecture that are not compatible with the current standard, it may cause data sharing issues.
