The document outlines the design phase of the System Development Life Cycle (SDLC), which follows the recognition of need and feasibility study phases. It details the types of system design, including logical and physical design, and emphasizes the importance of thorough design specifications to ensure ease of understanding, error reduction, and maintenance. Effective system design benefits developers by enabling early problem detection and facilitating modifications.

3. Design
System-development design is based
on system analysis. Which comes after
Recognition of need and Feasibility
study phase. Design illustrates in
detail about submitted systems:
– Specification
– Functional requirements
– Features
– Operations

5. Types of System Design
System design is divided into
two types:
• Logical Design- This type of
design the abstract
representation of the system.
• Physical Design- This type of
design the graphical
representation of the system

6. Benefits of Good System Design
Easy to understand for the developer of the system.
Make the system most error-free.
It helps to find problems in early detection if any.
Easy to Modify the system.
It decreases the maintenance problem.
