What are Data Models? | Aquro Help Center

A data model is a definition of which properties that a data item should have.

If you are used to using classic SQL databases, you may be used to creating a table with a set of columns and then storing the data in different rows. Aquro stores all data in an object database, which is handled slightly differently.

First, you design a model (the columns) and then you add different sets/collections of this model (tables which use those columns as a sort of data template or framework).

In other words, you first create the layout of the data and then you add one or more instances of this layout in your app.
