Description
System and analysis design is a critical phase in the development of any software system. It involves several steps to ensure that the system meets user requirements and functions efficiently. Here are the main components:System Analysis1. Requirements Gathering - Stakeholder Interviews:Engaging with users, clients, and other stakeholders to understand their needs and expectations. - Surveys and Questionnaires: Collecting structured data from a larger audience. - Document Analysis: Reviewing existing documentation to gather relevant information. - Observation: Watching how users interact with current systems. 2. Requirements Specification - Functional Requirements: Detailed description of system functionalities. - Non-functional Requirements: Performance, security, usability, and other quality attributes. - Use Cases: Scenarios detailing how users will interact with the system. 3. Feasibility Study - Technical Feasibility: Evaluating if the technology needed is available. - Economic Feasibility: Cost-benefit analysis. - Operational Feasibility: Assessing if the system will operate within existing organizational processes. -
1. System design
System design involves creating the architecture of a software system to meet specified requirements. This process encompasses defining the system's components, their interactions, and how they will work together to achieve the desired functionalities. Here’s a comprehensive overview of system design:
1. High-Level Design (HLD)
a. System Architecture
- Definition: Outlining the overall structure of the system, including hardware and software components.
- Components: Identifying major system components and their relationships.
- Architecture Styles: Choosing appropriate architecture patterns such as client-server, microservices, monolithic, or distributed systems.
b. Data Flow Diagrams (DFD)
- Purpose: Visual representation of data movement through
