    Project mention: Mathesar – An intuitive spreadsheet-like interface on Postgres | news.ycombinator.com | 2025-01-29

    Just a heads-up, I’m opinionated on this!

    Every app has some terminology you need to learn to use it effectively, we just think that terminology should actually map to how databases work, rather than being an arbitrary abstraction. Instead of inventing our own terms, we stick to tables, records, schemas, and relationships so that users who learn Mathesar are also learning concepts that translate directly to Postgres (or relational databases in general).

    Making software approachable isn’t about hiding complexity, it’s about presenting it well. The UI patterns you use determine whether a system feels intuitive, not whether the underlying mental model is simple. A well-designed interface can make even complex concepts feel natural, while a bad one can make simple tasks frustrating. Mathesar doesn’t make databases approachable by pretending tables aren’t tables, it makes them approachable by using familiar interactions, and progressively exposing complexity.

    We do want to work on surveys ("forms") soon, and we're definitely thinking about bulk actions and integrations as well. Please feel free to open a feature request on https://github.com/mathesar-foundation/mathesar/issues for anything that would particularly help your use case.
