Database represents data you want to have in Fibery: Task, Feature, Project, Vacation, Meeting, Asset, etc. Imaging that Database is a template with some data stored in Fields.
Fibery can’t work with just tables, like Excel. To add something into Fibery you have to have Database for that. For example, if you want to add some products with details like Name, Effort, Risk, etc, it is required to create Product Database in some Space and add the relevant Fields.
Add new Database
To add a new Database into existing Space, navigate to Space setup area and click New Database.

NOTE: Use singular term when naming Databases:
✔️ CORRECT: Task
❌ INCORRECT: Tasks
Newly created Database has a few Fields by default:
Name
Public ID
Description
Creation Date
Modification Date
Created By (User)
Feel free to add additional Fields to make the Database more useful.

Delete Database
To delete a Database, click on it in Customize Space section, click … and find Delete option:

NOTE: When you delete a Database, all data will be deleted as well. For example, if you delete Project Database, all Projects will be deleted. So make sure you don’t have anything important in there. (In any case, Undelete will help you if you did a mistake).
Rename Database
To rename a Database, just click on a Database name and type the new name.
