A Report on Systems Design
Systems design is the creative processes behind providing a very descriptive solution to one or many problems. When looking at the System Analysis Life Cycle we can see that in order to achive an optimal solution most of the work should be completed in the Analysis and Design Stages (Notice that these stages are some of the first to be undertaken)
Types of Systems Design
Conceptual and Technical Design
? Conceptual Design: What.
? Technical Design: How.
Simple Design Versus Detailed Design
General Design Concrete Design
System function Design effective input
System processing ways Design effective output
Size and scope Design files, tables and databases
System structure Design user interface
Hardware and software Design procedure
General processing flow Design KB and inference engine
System schedule Design networking
Things to be considered when attempting to model a problem
Applicability
? Capable of solving real world application problems
? Meeting the requirement of real applications
? Easy to use
Transferability
? Easy to get information from the world
? Easy to exchange information between the system and the user
? Easy to acquire knowledge and data
Flexibility
? It is feasible to expand or to reduce the function and the scale of a system.
? Easy to add or modify the knowledge/data in the system
Time Effective and Effeciency
? Capable of providing a solution in an acceptable time
? Computationally efficient
Reliability and Robustness
? Stability of the system
? Security of the DB/KB
? Protection of the system
