Your First Application in 20 Minutes › Defining the Project Entity

Defining the Project Entity

In CA Plex, you define objects and specify relationships between them with triples. As the name implies, a triple has three parts:

• A source object
• A verb
• A target object

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

Project known by FLD Project ID

In this example, Project (an entity) is the source object of the triple, known by (or known by FLD) is the verb and Project ID (a field) is the target object.

Note: In the CA Plex documentation, verbs are always printed in bold and often with their source and target object types (ENT known by FLD, for example).

Triples provide a simple, easily understood language for entering information into CA Plex. Here are some examples of triples that you will enter:

• Project has FLD Project Description
• Project Description is a FLD LongDescription
• Project described by DGM Project Diagram

In this chapter, triples are entered to define fields for the Project entity: an identifier, a description, and start and end dates for a project.

You use the Model Editor to view, add, edit, and delete triples.

The following is an example of the Model Editor as it appears after you complete this chapter.
