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 Credit Default dataset, we identified four entities.

Name	Description
Client	A client of the credit institution
New Application	A new loan application
Prior Application	A prior loan application
Consumer Loan	A Consumer loan

If you have registered the cash loan table too, you must register a 'Cash loan' entity.

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
Client	A client of the credit institution	CLIENT_ID
New Application	A new loan application	NEW_APPLICATION_ID
Prior Application	A prior loan application	PRIOR_APPLICATION_ID
Consumer Loan	A Consumer loan	CONSUMER_LOAN_ID

Step 5: Tag Columns Representing Entities

From the menu, navigate to the 'Explore' section and access the Table catalog.

---

In PRIOR_APPLICATIONS,

• APPLICATION_ID represents Prior Application.
• CLIENT_ID identifies Client.

---

In CONSUMER_LOAN_STATUS,

• LOAN_ID represents Consumer Loan.
• CLIENT_ID identifies Client.

---

In CONSUMER_INSTALLMENTS,

• LOAN_ID represents Consumer Loan.
