--- title: Create Relation Fields description: Step-by-step guide to connecting objects with relation fields. --- Relation fields connect records from different objects—for example, linking People to Companies. **Relation names cannot be changed after creation** (they affect the API). Plan your names carefully. ## Before You Start Decide: * Which objects are you connecting? (e.g., People → Companies) * Which is the "one" side? (e.g., Company) * Which is the "many" side? (e.g., People — many people work at one company) * What should the field be named on each side? See [Relation Fields](/l/ko/user-guide/data-model/capabilities/relation-fields) for relation types explained. ## Steps 1. Go to **Settings → Data Model** 2. Select the object where you want the relation (typically the "many" side) 3. Click **+ Add Field** 4. Select **Relation** as the field type 5. Choose the **target object** 6. Select **One-to-Many** or **Many-to-One** 7. Enter field names for **both sides** of the relation 8. Click **Save** ## Example: People → Companies * Go to **Settings → Data Model → People** * Add a Relation field * Target: **Companies** * Type: **Many-to-One** * Field on People: **Company** * Field on Companies: **Employees** Now each Person can be linked to a Company, and each Company shows its People. ## Deleting a Relation 1. Go to **Settings → Data Model** 2. Find the relation field 3. Click **⋮ → Deactivate** Links are preserved but hidden. Reactivate to restore. **Deleting a relation doesn't delete records.** Only the link between them is removed. ## Related * [Relation Fields](/l/ko/user-guide/data-model/capabilities/relation-fields) — types and limitations * [How to Import Relations](/l/ko/user-guide/data-migration/how-tos/import-relations-between-objects-via-csv) — bulk import linked records
