Study Notes
System Design Process
- System design is a model-building activity that converts the information gathered during analysis into models that represent the solution system.
- It is more oriented towards technical issues and requires less user involvement and more involvement by other systems professionals.
System Design Activities
- Design the Application Architecture and Software: includes decisions about the structure and configuration of the new system, as well as the design of the computer software itself.
- Design the User Interfaces: includes designing the user interface, which is everything the user comes into contact with while using the system.
- Design the System Interfaces: involves designing the component that enables systems to share information.
- Design the Database: includes identifying the type of database to be used, the database management system, and designing the internal properties of the database.
- Design the Security and System Controls: includes ensuring that the system has adequate safeguards to protect organizational assets.
- Design the Environment: includes designing the technology required to support the software application, including hardware, operating systems, and communication protocols.
System Design Perspectives
- For the application software component: identify the various subsystems and their relationships to each other.
- For the database component: identify the type of database to be used and the database management system.
- For the user-interface component: identify the general form and structure of the user dialog based on the major inputs and outputs.
System Design Outputs
- The output of the design activities is a set of diagrams and documents that describe, organize, and structure the system solution.
- The diagrams model and document various aspects of the solution system.
System Design Approaches
- There are three approaches to system design: Structured Design, Function-oriented Design, and Object-oriented Design.
- Structured Design: breaks down problems into multiple well-organized elements, allowing for simpler problem-solving.
- Function-oriented Design: divides the entire system into subsystems referred to as functions, with more information passing between the functions.
