The User "Guest"

1. The user comes to the Main page where the system prompts the user to enter "Username" and "Password", i.e. pass the authentication procedure. So the user can see a description of all the available books.

2. If the user passes the authentication procedure, then it acts as the user "Administrator" or as user "User".

2.4 Model architecture

The whole system contains 4 modules:

a) Interface module.

b) A module that contains the computational part (the basic algorithms).

C) The module responsible for the error.

d) A module file.

2.5 Criteria for system certification

The criterion for certification of a system is the testing:

a) Check the operation of all basic functions of the program (creation, deletion, editing of books and users, authentication, viewing of the description, the correct display of the selected books)

b) Check the correct operation of the database (correct entering, modifying and retrieving data).

3.2 Project subsystems

Interface

This module is a graphical shell intended to interact with the system. With it the user calls the required functions of the system. It contains many of the visual objects is designed to activate all of the features and functions of a software system. When you select a menu item or pressing any button to a specific action (user registration, authentication, logoff, etc.). The subsystem consists of three modules:

1. View all books. Allows you to view all the books registered in the library, it is not necessary to be a registered user.

2. The view taken of the books. Enables you to view workbooks that have been taken by a user but was not given yet and are not expired.
