Everything in Twenty is built around **objects** and **fields** — the building blocks of your data model.

## Objects

Objects are the tables that hold your data. Twenty comes with standard objects out of the box:

- **Companies** — Organizations you do business with
- **People** — Individual contacts
- **Opportunities** — Deals in your pipeline
- **Tasks** — Action items for your team
- **Notes** — Free-form text linked to records

You can also create **custom objects** for anything your business needs — projects, support tickets, products, contracts, or anything else.

## Fields

Fields are the properties on each object. Twenty supports a wide range of field types:

| Category | Types |
|----------|-------|
| **Basic** | Text, Number, Boolean, Date, Currency, Rating, Select |
| **Composite** | Address (street, city, state, zip), Full Name, Links, Phones, Emails |
| **Special** | Relation, File Attachment, JSON, Actor (who created/modified) |

Every object also gets automatic system fields: `id`, `createdAt`, `updatedAt`, `createdBy`, and `position`.

## Relations

Objects connect to each other through relations. A Company has many People, an Opportunity belongs to a Company, and so on. You can create custom relations between any objects, including many-to-many relationships.

## What makes this powerful

Unlike traditional CRMs where you're limited to pre-defined fields on pre-defined objects, Twenty lets you model your data exactly the way your business works. Custom objects get the same first-class treatment as built-in ones — including API endpoints, views, permissions, and workflow triggers.
