A standard data model or industry standard data model (ISDM) is a data model

A data model in software engineering is an abstract model, that documents and organizes the business data for communication between team members and is used as a plan for developing applications, specifically how data is stored and accessed....

 that is widely applied in some industry, and shared amongst competitors to some degree. They are often defined by standards bodies, database vendors or operating system vendors.

When in use, they enable easier and faster information sharing because heterogeneous organizations have a standard vocabulary and pre-negotiated semantics, format, and quality standards for exchanged data. The standardization has an impact on software architecture

The software architecture of a system is the set of structures needed to reason about the system, which comprise software elements, relations among them, and properties of both...

 as solutions that vary from the standard may cause data sharing issues and problems if data is out of compliance with the standard.

The more effective standard models have developed in the banking, insurance, pharmaceutical and automotive industries, to reflect the stringent standards applied to customer information gathering, customer privacy, consumer safety, or just in time manufacturing.

. While the format of the standard may have implementation trade-offs, the underlying goal of these standards is to make sharing of data easier.

The most complex data models known are in military use, and consortia such as NATO tend to require strict standards of their members' equipment and supply databases. However, they typically do not share these with non-NATO competitors, and so calling these 'standard' in the same sense as commercial software
