Student Information Management System

All the mark points are marked in the table, if you cannot find the evaluation point in the webpage, this table will help you.

evaluation point	link1	link2	link3	Note
Basic function – add	view	logic	data access
Basic function – display	view		data access
Basic function – search	view		data access
Basic function – sort	view		data access
Basic function – save to file(log)			data access
Basic function – read from file(log)	view		data access
Extended function – delete student	view	logic	data access
Extended function – modify student	view	logic	data access
Extended function – OO	introduction
Extended function – database	introduction	detailed design
Extended function – version control	introduction
Extended function – log	introduction		data access

The Basic function “sort” contians extended like sort by studentId, name, age, etc.
The extended function “log” appear too many times so I did not give the links here.

1.Introduction

This is a system for managing the students’ information (SIMS in short). The system contains three hierachical layers which are view, logic and data access.
At the very top layer-- view layer contains all human-computer interactions. All the client operations will be finished here.
The 2nd layer is the logic layer. It contains all logic operations including search for a student, sort the student grades, etc.
The 3rd layer is to communicate with database. It will automatically control the database with the order from logic layer.

Layer	Function	Note
View	All human-computer interactions.	No logic nor data control at all
Logic	Handle the orders from the view layer, all the memory operations will be executed here, but data operations will be sent to the 3rd layer	This is the core layer of the system
Data	Handle all the data operations from logic layer	Connection between memory and database

2.Outline design

2.1 Functions of system

This system is similar to a DBMS, it contains add, delete, modify and query for a database. The detailed functions design is shown in the graph below.
