Data Model

Tables store your application data. When you describe what you need, the system creates table definitions automatically in tables.bas.

What Is a Table?

A table organizes related data into rows and columns, similar to a spreadsheet.

id	name	phone	email
1	John Smith	555-1234	john@email.com
2	Maria Garcia	555-5678	maria@email.com

Creating Tables

Describe what data you need to store.

I need a customers table with name, phone, and email

10:30

customers table created with fields:

phone (STRING)

Adding Fields

Add new fields to existing tables through conversation.

Auto-sync	Changes deploy automatically

`field AS TYPE`	Define a field
`END TABLE`	End table definition

FIND Keyword

Query data using the FIND keyword:

Syntax	Description
`FIND * IN table`	Get all records
`FIND * IN table WHERE condition`	Filter records
