Java Bookstore System Graduate design overall design (1) _java

Java Bookstore System Project functional Requirements:

1, can carry out the operation of the user registration, modify basic information, delete and query.
2. The basic information of the book can be added, deleted, modified and query operation.
3, can fill in the purchase list, a purchase order with a number of specific purchase information, purchase books must be books management inside already have;
4, can fill out a sales list, a sales list with a number of specific sales information, the sale of books must be in the book management has been, and the number of sales can not exceed the current number of inventory, sales and modify the inventory corresponding to the inventory of books.
5, you can view the inventory of the details, you can follow the conditions to find the specific book inventory value.
6, the permissions of the simplification, do a fixed authority control. To the user according to the module into different operating rights of personnel, ad hoc a user admin, you can operate all the functions.

Basic project design:

★ Architecture Design:
Overall framework, module division
Module Division: User, book, purchase, sales and inventory of 5 modules

★ System Functional Structure Design:
Specific function modules for each function module
★ Database Design:
Project Framework Implementation: Sub-module, tiering, subcontracting, building applications
Core framework--implementation of each interface transformation
