The NIH Information Architecture specifies the key elements of information systems the NIH uses in executing its business processes. These elements include the information itself, the applications that use the information to enable the business processes, and how applications and information together support the enterprise's business functions.
Together with the Business Architecture the Information Architecture maps business systems, or "applications", and enterprise data to business processes. The information architecture also specifies which parts of the business process are supported by each application and where each type of data will be stored and managed.

NIH's Information Architecture is comprised of three sub-architectures: Applications, Data, and Integration.

Applications

The NIH Application Architecture, which is under development, represents NIH's application portfolio and identifies the business systems that enable and support the execution of NIH business processes. It provides a cross reference of application to business functions or processes to illustrate application boundaries.

Data

The NIH Application Architecture, which is under development, represents NIH's application portfolio and identifies the business systems that enable and support the execution of NIH business processes. It provides a cross reference of application to business functions or processes to illustrate application boundaries.

Integration

The NIH Integration Architecture, which is under development, consists of models that identify how applications are integrated to support end-to-end business processes or operations. It also includes NIH’s strategy for application integration.
