Unit 610: Information Systems Analysis and Design

1. Introduction to Information Systems Analysis and Design

• Definition and scope of information systems analysis and design
• Importance of effective system development processes
• Role of analysts and designers in system development
• Benefits of well-designed information systems

2. Systems Development Life Cycle (SDLC)

• Overview of SDLC
• Phases of SDLC:
  • Planning: defining scope and objectives
  • Analysis: understanding business needs and requirements
  • Design: creating system specifications and models
  • Implementation: coding, installation, and deployment
  • Maintenance: ongoing support and enhancements
• Importance of each phase and deliverables

3. Requirements Gathering and Analysis

• Purpose of requirements gathering
• Techniques for gathering requirements:
  • Interviews
  • Surveys and questionnaires
  • Workshops and focus groups
  • Observation
  • Document analysis
• Analyzing and documenting requirements
• Managing changing requirements

4. Data Modeling and Database Design

• Introduction to data modeling concepts
• Types of data models: conceptual, logical, and physical
• Entity-Relationship Diagrams (ERDs)
• Database normalization principles
• Designing databases to support system requirements
• Tools for data modeling and database design

5. System Design and Architecture

• Overview of system design process
• Designing system components and modules
• Defining system interfaces (user, hardware, software)
• Architectural styles and patterns (e.g., client-server, layered architecture)
• Ensuring scalability, reliability, and security in design

6. User Interface Design
