The coding test suggests using Mongo. I decided to go with SQL because I'm more used to it and would face less "surprises" during the test. That said, I'm certainly open to No-SQL.
I generally prefer to use the same database (usually PostgreSQL) in all environments, but I chose SQLite in development to make the evaluator's job easier when reviewing my project, since it requires zero setup.
- Development and test: SQLite
- Production: PostgreSQL
Install dependencies and create the database with bin/setup.
Just rails server.
Tests cover the Calculation model and logic and the Calculation endpoint. Run rails test.
