[PRIMARY FEATURE] Cache RateMyProfessor Ratings

[U-k-t]

User Story

As a developer, I want to cache professor ratings to prevent any application errors from occurring as a result of external factors.

Technical Task:

Cache professor ratings in the database so that queries will still execute correctly under heavy load and mitigate rate limiting by RMP.

Acceptance Criteria:

• Professor ratings stored in the database
• Logic written to determine when the rating will be queried from RMP and when it will be written from the database
• Logic to update the database upon an RMP query
