We need to deploy application(developed by Java) WAR file in client place which make use of MySql 5.0. But we would like to restrict the client (the application owner, not the webpage visitor) from modifying any data in the database. Is there any way to protect data. The client can make use of the application but they should not be able to change any value in database. How to do that?

    This is impossible; if you deploy the application at the client, he will have the credentials and will be able to log into the MySQL database and pretent he is the application. And thus he can make any change to the database that your application can.

    The only way to solve this securely is to make a tier between the client and your MySQL database, and make sure that you control this so that it is only possible to make ‘legal’ changes.
