OSU Course Analytics (Osuca)
Analyze student review responses for courses in the Computer Science (CS) program of Oregon State University (OSU)
Description
This program allows analyzing the online survey of course reviews from the CS students in OSU. It helps students answer questions such as:

Does course difficulty vary from term to term?
Does course difficulty increase if I take other courses in the same quarter?
Which course combinations are most difficult taken together?

It also exposes several services for client programs to query course analytics in JSON format. See Communication Contract for further details.

Windows
> $env:FLASK_APP = "osuca"

Communication Contract
Osuca returns JSON objects for the following valid HTTP GET requests:

/courses
/course-year-aggregates
/course-quarter-aggregates

For example, $curl http://localhost:5000/courses will return a JSON list of course objects to the clients.
UML Sequence Diagram
As shown in the diagram, Osuca requests a CSV document that resides in Google documents containing the scraped student responses. Then it serves the contents of this document in JSON form to clients.

Service Details
The following shows example responses to the requests.
