This chapter describes the input and maintenance of master data and provides a detailed description of master data properties.
Master data are basic input details essential for the construction of school timetables. They include the particulars of teachers , classes , rooms and subjects which are used to form the lessons in the timetable, but also other important information such as students or departments . You can generally enter new master data or modify existing master data via the menu item "Master Data" in the main tool bar (by clicking on the appropriate submenu).

Greyed-out items indicate functions that are currently inactive. This is normally the case when the use of the option requires an additional Untis software module.
Note: Adding menu items to menus
The figure shows additional entries below the menu item 'Master data formats' that are by default not displayed in your menu. The chapter Managing views explains how you can add several menu items to menus.
The master data categories 'Classes', 'Teachers', 'Rooms' and 'Subjects' are particularly important as they are the main building blocks for the construction of lessons. We will therefore refer to these types of master data s elements .
All master data are managed in so-called views. Views are windows designed for the input of new master data and the maintenance (i.e. modification) of existing master data. All master data views are essentially very similar in use and structure. The following chapter describes the similarities between different master data views.
