Develop the Resource Tier

This section is the actual service development, which involves the following four main steps:

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

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

First, we create two instances of Item with a Feature list and then check for two instances of Item. Later, we do an update and test whether the changes were echoed. Finally, we detach one occurrence and test whether the count is one.
