The document discusses the system design for a student management system. It includes database design diagrams for admission and examination modules with tables like student details, courses, exams etc. It also includes activity diagrams for various functions like login, admission process, student search, setting subjects etc. The system design aims to transform customer requirements into an implementable form with modules, data structures and algorithms.

- 2. Project Id: 32 SystemDesign INTRODUCTION During analysis, the focus is on what needs to be done intendment of how it is done. During design, decisions are made about how the problem will be solved, first at a high level, then at increasingly detailed levels. System design is the first stage in which the basic approach to solving the problem is selected. During system designing the overall structure and style are decided. The system architecture is the overall organization of the system into components called system. System design deals with transforming the customer requirements, as described in the SRS document, into a form that is implement able using the programming language. Certain items such as modules, relationships among identified modules, data structures, relationships between the data structures, and algorithms for implementation should be designed during this phase. As a system designer we are tried to take following design decisions: • Organize the system into modules • Organize sub-modules for each module • Allocate tasks to processors • Choose an approach to manage data store • Handle access to global resources • Choose implementation logic CCET (IT) 88
