# Messages

### Purpose

This documentation explains the most important error messages and system messages displayed by the MaxDB database system and recommends how you should deal with these messages ("user action").

Every message has a unique message number that is assigned to a number range. You can use this number range to find out which component of the database system caused the error message to be displayed.

For more information about the database system, see Concepts of the Database System. For quick access to the entire documentation and an explanation of the most important terms, use the alphabetically sorted glossary.
