Comprehensive System Analysis of Student Registration System Report

This report presents a system analysis of a student registration system. Part A focuses on the case study, identifying entities through noun phrase analysis, relationships through verb analysis, and constructing an Entity Relationship Diagram (ERD) using Chen's notation. It also includes a detailed data dictionary for entities, specifying attributes, data types, constraints, and criteria. Part B covers the case, presenting a Context Data Flow Diagram, a Level-0 DFD, and a Level-1 DFD to illustrate the system's processes. Furthermore, it incorporates a CRUD (Create, Read, Update, Delete) matrix to model data and process interactions, offering a comprehensive overview of the system's design and functionality. The report provides tables and figures to support the analysis and design of the system.
