Develop the Resource Tier

This lesson is the service development, which involves the following four steps:

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

We will begin with the entity and finish with the REST service.

First, we create two instances of User and then eventually check for two instances of the user. Later, we do an update and test whether the changes are still in place. Finally, we remove one existence and test to see if the count is one. Also, we add two variations of Group and associate them with the remaining instances of the User.
