Classification of System Analysis
Classification of system analysis is as follows:
- Formal System – Planned or Documented procedures. For example – Scheduled meetings.
- Informal System – Not described by Procedures. For example – Sales orders procession system through telephone call
- Physical System – Tangible entities that may be static or dynamic. For example – Computer.
- Abstract System – Conceptual Entities. For Example – Company.
- Open System – Receives input and provides output to the environment. For example – Organisation.
- Closed System – Isolated from environmental influences. it is rare in reality
- Manual System– Require human intervention. For Example – The railway ticket counter
- Automated System – Does not Require human intervention. For example – Traffic control system
Real Time Systems – Interactive processing system with severe time limitations. There are two types of Real Time systems. They are:
- Hard Real Time Systems complete critical tasks on time. For example – Radar System
- Soft Real Time Systems are the less restrictive type of real time systems. For example – Industrial Control System
System Users – The people who use information systems.
- Internal Users – Employees of the business
- External Users – Customer of the business
System Analysis and Design Interview Topics for Freshers
System Analysis is the “what” before the “how” in system design. It provides the essential roadmap for crafting a system that is both effective and efficient in solving the intended problem. “Imagine you’re building a dream house. You wouldn’t start hammering nails without a detailed blueprint, right?”The same goes for software development.”
System analysis is the blueprint, while system design translates it into the actual system.
