@Qantumentangled it depends on the type of data he's storing. NoSQL is great for unstructured, document-based data but if there's a lot of relational connections, SQL-based can perform better and be more manageable.
@rb Well he's building a mock-up framework for a CRM so HEAVILY dependent on relational data. But somehow he wants it to run locally in userland... I'm not sure he's thought the whole thing through technically yet, so I'm helping one step at a time lol.
