Everything in Clara is built around **objects** and **fields** — the building blocks of your data model. ## Objects Objects are the tables that hold your data. Clara 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. Clara 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, Clara 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.
