Develop the Resource Tier

The next step is the actual service development, which includes four key steps

• Creating the entity
• Creating the data access tier
• Creating the business service tier
• Creating the JSON based REST competencies

We will first go over the entity and work our way to the REST service.

First, we create four instances of Worker and then create two instances of join. Next, we remove one instance and check to see if the join count is one.
