The MySQL database shell

This is a task for a coursework, a strong cool design is not necessary. It's minimal and simple. You need to write a visual shell to the existing database. The form for subscriber registration, the form for drawing up the application, the order for connecting the subscriber, naturally related table fields should be filled in automatically. The search button should be implemented. (theme - the conclusion of contracts for the connection of the Internet provider) I throw off the scheme of document flow, er model, logical model. I'll give you access to the database later.
