}
Reviewing the logic in your unit test (see Listing 15-6), you are going to start by migrating the JDBC into the
MongoDB server; here you are using the two implementations of the DocumentDAO interface. And you are going to
begin by adding the types that should be in the types collection, and then the documents that should be in the docs
collection. After running the unit test you can open a new terminal (DOS or Unix) and connect to the MongoDB server
to see if the data is there.
Figure 15-1 shows the databases and the collections created.
