What is a database?   
A database is a collection of data that is organized so that its contents can easily be accessed, managed, and updated within a structure (Quote-Merriam-Webster Online Dictionary “http://www.m-w.com/home.htm”).

What is the Database Manager?   
The Database Manager is a web based MySQL client that allows you to create and manipulate a maximum of two MySQL databases. If you require more than two databases then you may utilize a different type of database such as: MS Access or MS SQL.

Database Manager is best used for creating databases and tables. For populating a database, you should consider using a script (PHP, ColdFusion) or CGI.

How does Database Manager work?     
Database Manager builds SQL statements from the various options that you may choose. This application allows you to review the queries that have been created before execution. This is the reason for the "Build SQL Query" button. Viewing the Query gives you an opportunity to review the query before running it. Clicking the "Run SQL Query" button submits the query to the SQL server.
