IGNOU MBA MMPC-08: Information Technology for Managers
Unit 9: Building Information Systems
Introduction
Building an Information System (IS) involves planning, designing, implementing, and maintaining a system that meets the needs of an organization. This unit explores the methodologies, life cycle, development tools, and challenges of building an effective IS.
1. Understanding Information Systems
1.1 Definition and Importance
- An Information System (IS) is a structured framework that collects, processes, stores, and distributes information.
- Helps in decision-making, process automation, and improving efficiency.
1.2 Key Components of an Information System
- Hardware: Physical devices like servers, computers, and storage units.
- Software: Applications, databases, and operating systems.
- Data: Raw facts that are processed into meaningful information.
- People: Users who interact with the system.
- Processes: Procedures that guide data input, processing, and output.
2. Information System Development Life Cycle (SDLC)
2.1 Phases of SDLC
- Planning: Identifying the need for an IS and defining project goals.
- Analysis: Gathering requirements and understanding existing systems.
- Design: Creating system architecture, database models, and interfaces.
- Implementation: Coding, testing, and deploying the system.
- Maintenance: Updating and troubleshooting after deployment.
2.2 System Development Methodologies
- Waterfall Model: Sequential approach with defined phases.
- Agile Development: Iterative approach with continuous feedback.
- Prototyping: Creating a preliminary model before full-scale development.
- RAD (Rapid Application Development): Focuses on quick prototyping and user involvement.
3. Tools and Technologies for Building Information Systems
3.1 Software Development Tools
- Programming Languages: Python, Java, C++.
- Database Management Systems: MySQL, Oracle, MongoDB.
- Development Platforms: .NET, Node.js, React.
3.2 Emerging Technologies in IS Development
- Cloud Computing: Enables remote storage and computing.
- Artificial Intelligence (AI): Enhances automation and decision-making.
- Blockchain: Ensures secure transactions and data integrity.
- Internet of Things (IoT): Connects physical devices for real-time data exchange.
4. Practical Applications and Experiments
4.1 Experiment: Building a Simple Database System
Objective: Design a basic inventory management system using MS Access or MySQL.
Steps:
- Define tables for products, suppliers, and transactions.
- Create relationships between tables.
- Develop queries for stock management and reporting.
4.2 Experiment: Developing a Web-Based Information System
Objective: Build a basic student management portal using PHP and MySQL.
Steps:
- Create a front-end form for student registration.
- Develop a backend to store and retrieve student data.
- Implement basic authentication for secure access.
