Sure! Here’s a clear and simple explanation of System Design and its Classification, along with the System Pyramid Architecture used in System Analysis and Design:


Subject: System Analysis and Design

Topic: System Design & Its Classification

Focus: System Pyramid – 3-Level or 4-Level Architecture


What is System Design?

System Design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specific requirements.

It comes after system analysis and aims to convert business requirements into technical solutions.


Types (Classification) of System Design

System design is broadly classified into:

1. Logical Design

2. Physical Design


System Pyramid Architecture (3 or 4 Levels)

A System Pyramid shows the hierarchy of information systems in an organization.


Option A: 3-Level Architecture

Level Type of System User Level Purpose
Top Strategic Level (EIS) Executives (CEO) Long-term planning & forecasting
Middle Tactical Level (MIS/DSS) Managers Medium-term decisions & analysis
Bottom Operational Level (TPS) Staff/Workers Day-to-day transaction processing

Option B: 4-Level Architecture (more detailed)

Level System Type User Example
1. Strategic Executive Information System (EIS) Top Executives Annual reports, Forecasting
2. Tactical Decision Support System (DSS) / MIS Middle Managers Sales trends, Budget planning
3. Knowledge Knowledge Work System (KWS) / Office Automation Knowledge workers CAD, Word Processing
4. Operational Transaction Processing System (TPS) Front-line staff Billing, Payroll, Order Entry

Visual Summary: System Pyramid (4-Level)

[ EIS ]
── Strategic (Executives)

[ DSS / MIS ]
── Tactical (Managers)

[ KWS / OAS ]
── Knowledge (Engineers/Clerks)

[ TPS ]
── Operational (Daily Users)
