Button text is "Login" function is to query the database to determine the adoption of the current user name and password are correct, if the right pop-up "login successful" dialog box if the failure of the pop-up "login failed" dialog box.
2 use OOP to achieve the three-tier structure.
3 the application of the abstract factory pattern, making the program can access the SQL database can also visit the ACCESS database, access to different database configuration file by modifying the configuration of the realization.
