System Design Course

System Design came into existence before World War II when the engineers were facing complex control and communication problems. They decided to formalize their work as a new discipline that comprised of cybernetics, information theory and operations research. The phrase ‘System design’ bridges the gap between domain problem and the existing system in a feasible way. This blog will provide in-depth knowledge of System Design courses.

What is System Design?

It is a process of defining elements of the system such as modules, interfaces, architecture, and data for requirements along with specific needs of a startup business or any industry through designing of a running system. Use of this approach standardizes work into a framework with precise and accurate information. There are various subsets of System Design:

  • Logical Design: Logical Design explains inputs, outputs, databases and procedure all in processes which satisfy user requirements. This design also provides an abstract representation of inputs, data flows and outputs in a system. E-R designing modelling and data flow diagram are used.
  • Physical Design: This design relates to the process of actual input and output of a system. Management of how data is verified, processes and displays the result are main criteria of physical design.
  • Architectural Design: Architectural design is also called the high level of design of system architecture and explains the roots and nature of the system.
  • Detailed Design: Detailed Design follows the design of Architectural design and majorly emphasis on the development of every subject.

There are three primary uses of System Design while designing system, which one has to be taken into consideration can be evaluated by the following:

  1. Reliability: It means the system able to go through faults or problems to prevent failures and shut down completely. System Design-build fault-tolerant systems using fault intolerant parts which is one of its advantages.
  2. Scalability: It refers to systems able to perform and during the situation, workload gives reasonable performance. System designs are used to reduce the efforts of the user and overcome the problems.
  3.  Maintainability: It means writing code that could be understood and modified by the one who is not the original owner of the code.

Why pursue System Design Courses?

By saving time and effort, a System Design course specializes in developing best artwork which helps in the creation of information systems. It is used to boost efficiency, solve internal problems and broadcast opportunities while making work simpler and easier by successfully achieving the desired results. Advantages of pursuing a System Design course are as follows: 

  • Helps various companies and industries by reducing their system downtime, reduce costs and accelerate up the maintenance work.
  • Aids new users training so that users can understand the flow of the system easily.
  • Assists in solving troubleshooting problems and aid the manager to take better final decisions for the organisation.

System Design as a Field of Study?

System Designs is more than visual guidelines and UI. They are living documents, usually created by designing groups and companies which intended to bring in a new creative angle in the user interface. The process includes: 

  • Business processes designing and redesigning
  • Data model defining
  • Events and its procedure are defined
  • Application designing
  • Designing process, events, services and data will work together
  • Security of the system is defined
  • Technologies are defined which are used as components, APIs, application and libraries.
