Data Model

Data Models

The Collections data model provides no-code configuration and management for any SQL database. You control not only the configuration of tables, columns, and relationships, but also how users view and manipulate data.


Collections is an SQL database wrapper. A database is a collection of data stored in a computer in a structured manner, and the specific way it is structured is called a data model.

Types of Relationships

Collections provides one method for relation-linking tables.

  • One to Many — Each row in a data table can be linked to many rows in another data table. Note: In the data model, Many-to-One Relationship and One-to-Many Relationship mean the same thing.
