3. Register Entities

What is an Entity?

In FeatureByte, an Entity represents real-world objects or concepts. While entities are typically associated with a primary key or foreign key in the data, they can also be represented by categorical columns that define groups of related objects. For example, a City entity may represent multiple customers, and a Product Group entity may encompass multiple products, even though neither is explicitly used as a foreign key.

Step 1: Identify Entities in Your Data

In the Loan Applications dataset, we identified six entities.

Name Description
New Application A new loan application
Client A client of the credit institution
BureauReportedCredit A report from the Credit Bureau
PriorApplication A prior loan application
Loan A loan
Installment An installment payment

Step 2: Decide their Serving Name

An Entity's Serving Name is the unique identifier used to recognize the entity during a serving request in FeatureByte. You can choose any name that suits your needs, provided it is not already assigned to another entity.

Name Description Serving Name
New Application A new loan application SK_ID_CURR
Client A client of the credit institution ClientID
BureauReportedCredit A report from the Credit Bureau SK_ID_BUREAU
PriorApplication A prior loan application APPLICATION_ID
Loan A loan LOAN_ID
Installment An installment payment INSTALMENT_ID

Step 3: Register Entities

Navigate to the Entity catalog from the 'Explore' section of the menu.

Repeat this for each entity:

  1. Click Register Entities.
  2. Fill in the form: the Entity's Name, its Serving Name and optionally its description.
  3. Confirm by clicking Save Entity.
