I've downloaded the MySQL Server 5.1 and developed a small database using the MySQL Command Line Client. However, now I must update a structure of some tables, include some foreign keys, etc. In my opinion, it is not very comfortable to use the MySQL Command Line Client and the "Alter" statement. Maybe, there exist some software with a user-friendly interface to improve/update/develop MySQL databases. For instance, I would like to visualize the relationships between tables. Please, give me some advice on this question. Thanks!
