Using Inheritance to Define the Project Entity

You have now defined the fields in which the Project entity stores data, and specified the Pattern Library fields from which those fields inherit. In the next step, you give the Project entity a user interface and functionality to interact with a database.

You again use inheritance to add this functionality. In fact, you do it with only two triples:

Project is a FOUNDATI/EditDetail
Project is a STORAGE/RelationalTable

The first inheritance triple gives your entity the ability to display and process a user interface. The second inheritance triple provides the functionality to read Project records from, and write Project records to, a relational database.

The step-by-step instructions that follow help you better understand the consequences of entering these two triples.
