Describes how to build specific types of applications Web-based insurance applications, for instance on top of the technical architecture, which normally involves different sets of developers and benefits from a separate architecture. Describes how to implement the technical architecture on specific technologies and products. Describes how to keep the applications operational. In the figure, red boxes represent the different types of requirements that must be satisfied by IT solutions. The blue boxes represent architectures that span the entire enterprise and multiple products or applications.
Green boxes represent models that are developed for a specific product or application.
This defines the entities and processes used across all the products or applications developed by an enterprise. This plan describes the set of products that need to be deployed and suggests a sequence for their development. The technical architecture is different from the set of products and technologies that will be used to build the application. The technical architecture describes the design for common infrastructure, services, and frameworks that support all of the enterprise applications to be developed. The program requirements identify the different types of applications that will be built over time.
