A data class can be visualized as a table in the Configuration Management Database (CMDB). Each data class has a set of attributes that define its properties. When you create a data class, you can customize it by adding, editing, and deleting its attributes.
To create a custom data class
In the left pane, expand Notification Server > Resource and Data Class Settings > Data Classes > CMDB Data Classes, right-click the folder where you want to create a custom data class, and then click New > Editable Data Class.
The name of the database table that is linked to the data class is created from the name of this data class. It begins with the prefix Inv_ followed by the data class name. The spaces in the data class name are replaced with the underscore character. Note that the table name persists even if you later change the name of the data class.
