Data Collection from Sando: Study of Recommendation Usage

We collected two data sets in order to answer the following research questions:

• RQ1: How often do developers use Coronado’s recommendations during their normal work to improve their queries?
• RQ2: Do developers seem satisfied with queries constructed from Coronado’s recommendations?
• RQ3: Are Coronado’s recommendations more helpful to users that are not familiar with the source codebase?
