Help Xu Brother's writing industry _ entry level: A simple database management system

Help the brother write a specialized course of homework. Write this system for the first time.

Let's record the traditional C/S model I understand. (Temporary superficial understanding, not necessarily completely accurate):

Why not have the server side, not only the client and the database, that is, why do not put the operation of the data on the client?

1) All put on the client, you can disassemble, the data how to get all know, not too safe.

2) The server side has one, the client can have multiple, so that the client can be managed through the server side. For example, the server side can know the number of users currently logged on to the client.

There may be other reasons.

After consulting the powerful and friendly classmates, I decided to deal with this problem:

1) because it is the first time to write something like this, for simplicity, no server-side, only with the client and database.

2) in order to be able to use this system on other computers to log on can also operate the corresponding database, the database is built on its own computer, and allow the database to accept access from the network (although not yet know how to implement).

Let's finish the UI today and then go ahead and write
