Entities are the subjects (aka randomization unit) of your experiments. For example, if you are a food delivery app, and you want to run experiments on both Restaurants and Customers, you would have a restaurant entity and a customer entity. Eppo creates a user entity by default, but you can add additional entities or edit the name of user if necessary.
Assignment, Dimension, and Fact SQL's can be attached to entities -- for example, an assignment SQL attached to a user would pull the assignments of users into different experiment groups.
Creating a custom Entity
To create a custom Entity, navigate to Definitions in the left menu bar from the Eppo homepage, then click Manage Entities.
A modal should pop up showing all the existing entities and their attached SQL's. Click + Create Entity to create a new entity.
In the example above, we created a new entity called Company
Click Confirm and then Save Changes.
