Products that do what Datalevin – a simple, fast, and versatile Datalog database does

After 6 years of open source development, Datalevin has now reached 1.0. The goal of the project is to have better ergonomics than a SQL database for OLTP workloads. We have made Datalog practical by being competitive in relational and graph query performance, and by integrating full-text, vector search and document indexing into the same fact-based data model. I am the maintainer and happy to answer any questions.

    As a software engineer, it's frustrating to see those who can't code stuck with spreadsheets as their most powerful data tool. This is especially true when there is such a thin layer that exists to access arbitrarily powerful data and AI/ML tools (typically just Python and pandas/SQL). I built Regrail last year to demonstrate a visual, procedural tool that abstracts the primitives of data engineering. It uses a block-based editor that allows users to see the changes they are making to tables step by step. You can think of it like a visual DAG builder. I believe that data literacy…

    Hello HN! I've been working on Atomic Database[1] for almost exactly a month now, having restarted from an earlier Hackathon prototype version. Atomic Database is a deductive database like Datalog that has a useful GUI interface, a natural language query system, smart metadata storage, and gradual typing capabilities. The actual database backend of all this is based on Entity Attribute Value triples currently (I don't forsee changing it, as yet!). This is still very much a prototype, but I feel like I'm at the stage in its evolution where I need some outside input and, possibly, help. To…
