Creating the Courses Collection

Your first application created a single student record for the student collection. In this part, you’re going to populate the course collection.

Populating the course details collection

You can use the same technique to build a store for the courses. Here’s a quick reminder of the course document structure:

art history
graphic design
fine art

{
  "course-name": "art history",
  "faculty": "fine art",
  "credit-points" : 100
}

{
  "course-name": "graphic design",
  "faculty": "media and communication",
  "credit-points" : 200
}

{
  "course-name": "fine art",
  "faculty": "fine art",
  "credit-points" : 50
}

The code should be familiar to you; there’s not much difference between writing to the course collection and writing to the student collection; you just have more records to deal with:

Unresolved include directive in modules/tutorials/pages/java-tutorial/creating-the-courses-collection.adoc - include::3.2@java-sdk:student:example$InsertCourses.java[]

1	Note that you’re now writing to a different collection.

Make sure that you’ve created the course-collection in the admin console before you attempt to run the program.

You can use maven to run the application:

mvn exec:java -Dexec.mainClass="InsertCourses" -Dexec.cleanupDaemonThreads=false

Use the admin console to make sure the documents have been created in the correct collection.

Next steps

So you’ve created a cluster, a bucket, a scope and two collections. You’ve also populated your collections with documents. Well, a database isn’t much use until we can retrieve information from it, which is what you’re going to take a look at in the next part.
