# Master Data

**Master Data** section houses the core data, for example clients, vessels, etc., accounting parameters and any other data required to successfully operate the different modules of the system. Master Data is a single source of basic business data used across the VMS in the modules and is shared by multiple users. To enable full usage of the system it is necessary to enter data into this section.

Each master data page follows the same design where you get a list of master data when opening the page. Create a new master data object with the + button above the list and maintains the master data object by open a drawer when clicking a master data object in the list.<br>
