The main objective of Phase C or the Information Systems Architecture is to develop the target architecture for any Information Systems.
The Information Systems Architecture can be broken down into two separate architectures:
- Data Architecture
- Application Architecture
The Information Systems Architecture should be able to describe in detail how the enterprise or organisations Information Systems Architecture will facilitate:
- The Identification of any Architecture Road-map Components based on a gap analysis
- The Business Architecture
- The Architecture Vision
The main objective of the Data Architecture is to determine the sources and types of data that will be required to support the organisation or business. It is imperative that the Data Architecture should be able to be easily understood by any stakeholders.
The main objective of the Application Architecture is to determine the specific types of systems that will be required to process any data and to support the organisation or business.
