Defining Entities › Introducing the Model Editor

Introducing the Model Editor

To create an application, you define objects and the relationships between them. In this lesson, you create an entity called Project, specify what information you want your application to store about projects, and add functionality that enables end users to create, edit, and delete projects.

In CA Plex, you specify relationships between objects in a model using triples. A triple is comprised of three parts: the source object, verb, and target object.

For example, in this tutorial, you use the following triple to define a unique identifier for the Project entity:

Project known by Project ID

The triple is an instance of the abstract triple ENT known by FLD. Whenever you want to designate a unique identifier for an entity, also known as its primary key, you use this triple, replacing ENT with the name of your entity, and FLD with the name of your key field.
