    About the data base server working on MySQL. A database server never changes or deletes the data in a database by itself; someone or something has to give the command for this to happen. Examples of commands that a user could give to the database server are delete all data about the vehicle with the registration plate number DR-12-DP or give the names of all the companies that haven’t paid the invoices of last March.

    This means that data in a database remains there permanently until it is changed or deleted explicitly. If you store new data in a database and the database server sends back the message that the storage operation was successful, you can be sure that the data will still be there for tomorrow (even if you switch off your computer). This is unlike the data stored in the internal memory of a computer. If the computer is switched off, that data is lost forever; it is not constant.

    Re: Data base server working on MySQL

    Commands are relayed to a database server with the help of special languages, called database languages. Users enter commands, also known as statements, that are formulated according to the rules of the database language, using special software; the database server then processes these commands. Every database server, regardless of manufacturer, possesses a database language. Some systems support more than one. All these languages are different, which makes it possible to divide them into different groups.

    The relational database languages from one of these groups. An example of such a language is SQL. The database server store data in a database.

The manner in which a database server stores information on these media is very complex and technical, and this book does not explain the details. In fact, you do not need this technical knowledge because one of the most important tasks of a database server is to offer data independence. In this way the data base server working on MySQL.
