ADM Phases & Objectives – Phase C – Information Systems Architecture
- The objective of Phase C is to develop Target Architectures covering either or both (depending on project scope) of the data and application systems domains.
- Information Systems Architecture focuses on identifying and defining the applications and data considerations that support an enterprise's Business Architecture; for example, by defining views that relate to information, knowledge, application services, etc.
ADM Phases & Objectives – Phase C – Information Systems Architecture – Data Architecture:
- Understandable by stakeholders
- Complete and consistent
- Stable
ADM Phases & Objectives – Phase C – Information Systems Architecture – Application Architecture:
- The objective here is to define the major kinds of application system necessary to process the data and support the business.
- It is important to note that this effort is not concerned with applications systems design. The goal is to define what kinds of application systems are relevant to the enterprise, and what those applications need to do in order to manage data and to present information to the human and computer actors in the enterprise.
- The applications are not described as computer systems, but as logical groups of capabilities that manage the data objects in the Data Architecture and support the business functions in the Business Architecture. The applications and their capabilities are defined without reference to particular technologies. The applications are stable and relatively unchanging over time, whereas the technology used to implement them will change over time, based on the technologies currently available and changing business needs.
