System Analysis and Design IT243 College of Computing and Informatics

You will conduct a systems analysis project by performing 3 phases of SDLC (planning, analysis and design) for a small (real or imaginary) organization. The actual project implementation is not required (i.e., no coding required). You need to apply what you have learned in the class and participate in the team project work.

This project should follow the main steps of the first three phases of the SDLC (phase 1, 2 and 3). Each phase must include detailed description and diagrams to illustrate the analysis and design process.

Part 1: Planning Phase

Learning Outcomes: Lo1: Describe the role of analysis and design in software development. Lo4: Use most common analysis and design techniques with comfort.

Requirements:

  • Project identification: Provide Project Title, Project Description clearly stating the Core Problem to be solved, Primary Customer, and Stakeholders. (1 mark)
  • Feasibility studies: Conduct and document Technical Feasibility, Economic Feasibility, and Organizational Feasibility. (1 mark)
  • Development methodology: Adopt an SDLC development methodology suitable for the project. (1 mark)
  • Work plan: List the Tasks to be Performed and develop a Work Plan using a Gantt Chart. (1 mark)

Insert diagrams as needed within this section to illustrate the planning process.

Part 2: Analysis Phase

Learning Outcomes: Lo2: Recognize software requirements and analysis to properly assess the problem faced by the client and suggest an appropriate solution. Lo3: Design a system applying principles of object-oriented design.

Requirements:

  • Business requirements: List functional and non-functional requirements of the system. (0.5 mark)
  • Use Cases: Create detailed Use Case diagrams capturing system interactions. (1 mark)
  • Process Modeling: Model processes using Data Flow Diagrams (DFDs). (1 mark)
  • Data modeling: Develop Entity-Relationship (ER) diagrams to model data structures. (1 mark)

Insert corresponding diagrams within this section to demonstrate your analysis work.

Part 3: Design Phase

Learning Outcomes: Lo2: Recognize software requirements and analysis to properly assess the problem faced by the client and suggest an appropriate solution. Lo3: Design a system applying principles of object-oriented design. Lo4: Use common analysis and design techniques with comfort.

  • Architecture design: Select an appropriate software architecture for the system. (1 mark)
  • Data storage design: Provide the type of data storage design employed (e.g., relational databases, NoSQL, files). (0.5 mark)

Insert relevant diagrams illustrating your architecture and data storage choices.

Introduction

Developing an effective information system necessitates a systematic approach through the Software Development Life Cycle (SDLC), which encompasses planning, analysis, and design phases. This report demonstrates the application of SDLC phases to a hypothetical organization, focusing on defining requirements, designing systems, and proposing suitable architecture and data storage solutions.

Part 1: Planning Phase

The selected project is the development of an Inventory Management System for a mid-sized retail store. The core problem revolves around inefficient manual tracking of stock levels, leading to overstocking or stockouts. Stakeholders include store managers, sales personnel, suppliers, and customers. The primary customer is the store management, seeking a solution to streamline inventory processes. A feasibility study indicates technical feasibility (available technology), economic feasibility (cost-benefit analysis shows savings), and organizational feasibility (staff readiness to adopt new system). The SDLC methodology adopted is the Agile model to allow iterative development and flexibility. The work plan outlines tasks such as requirements gathering, prototyping, testing, and deployment, scheduled over a 12-week Gantt chart.

Part 2: Analysis Phase

Business requirements highlight the need for real-time stock updates, barcode scanning integration, low latency, and user-friendly interfaces. Non-functional requirements include system security, scalability, and high availability. Use Case diagrams depict interactions such as 'Update Stock Levels,' 'Generate Reports,' and 'Order Supplies.' Data Flow Diagrams model processes such as stock entry, sales transaction, and restocking. ER diagrams define entities like Product, Supplier, Stock, and Transaction, with relationships illustrating stock levels and order histories. These models capture system operations and data dependencies comprehensively.

Part 3: Design Phase

The architecture is based on a three-tier client-server model, comprising a presentation layer (web interface), application layer (business logic), and data layer (database). This layered architecture ensures modularity, ease of maintenance, and scalability. For data storage, a relational database (MySQL) is selected to support complex queries and ensure data integrity. The ER models inform the database schema design, optimizing relational mappings and index strategies for performance.

Conclusion

The systematic analysis and design methodologies guide the development of a robust inventory management system that addresses the core problems faced by the retail store. By selecting an appropriate architecture and data storage approach, the system is designed to be scalable, secure, and efficient, meeting both functional and non-functional requirements.
