At this point in the course project, the project’s goal has been expressed, turned into a preferred design concept as the basis for development, and transformed into a set of requirements. The next step is to develop an architecture (or an update to an existing architecture for fielded systems) to guide design and development. This architecture is the fundamental organization of the system, embodied its components, their relationships to each other and the environment, and the principles governing its evolution. In a sense, the system architecture describes the potential to meet user expectations and how the major components satisfy important design requirements. It is also an opportunity to highlight novel features to show their potential to outperform competing products.
A system architecture concerns itself with the GIS software, the hardware, network resources, databases, and the people who build, maintain, and use these systems. An Enterprise GIS is the implementation of GIS infrastructure, processes and tools at scale within the context of an organization. This week, you will be describing the basic components of the system architecture and enterprise GIS framework of your GISystem Design including the following:
GIS software
-
- GIS hardware
- Network Resources
- Database Design and Requirements
- Enterprise GIS components
- Performance Considerations
- Maintenance Considerations
- Security Considerations
Once you are ready, move onto the Lesson 5 Term Project: System Architecture.
