dRofus Data model
Database and Project
A Database can contain one or more Projects.
Rooms
Room Instances. Not Necessarily surrounded by walls (can be a functional area within a larger space).
Room Structure
Room Functions is a hierarchical structure with a collection of rooms. Usually represent the end users' future organization and performance of the building. The rooms will get a room function number that indicates the location within the room function structure.
Room Groups are an additional way of organizing rooms into groups.
Item list
Item list is a list of occurrences of Items for each Room or Room Template
Item list created from an Item list to a Room Template
Item list created from an Item List Template
Item list created uniquely for the Room.
Templates for rooms
Room Templates are virtual spaces that transmit data and lists of items to one or more connected room instances. Templates can be used to create rooms, and any changes made to the template will be reflected in the data and item list of the corresponding rooms. Additionally, rooms can be created as "derived" from a template, meaning that the data and item list will be copied but not updated when changes are made to the template.
Items, Item Occurrences, and Product
Item Groups
Item Groups is a hierarchical structure with a collection of Items. Groups are usually organized intuitively based on Item type /categories. Items will get an Item number indicating where in the Item group structure it is located.

Occurrence
When an Item is placed in the project, it is called the Occurrence of an Item. It can be connected to a room or a system or added to the project as an Occurrence. If the occurrence is a member of a system, it’s called a “component.” If it owns a system, it is called a “System Component.”
