The first version of Datomish [was written in ClojureScript](https://github.com/mozilla/datomish/tree/master), targeting both Node (on top of `promise_sqlite`) and Firefox (on top of `Sqlite.jsm`). It also works in pure Clojure on the JVM on top of `jdbc-sqlite`.

It also works in pure Clojure on the JVM on top of `jdbc-sqlite`. The name was changed to avoid confusion with [Datomic](http://datomic.com).

This branch is for rewriting Datomish in Rust, giving us a smaller compiled output, better performance, more type safety, better tooling, and easier deployment into Firefox and mobile platforms.

Datomish is intended to be a flexible relational (not key-value, not document-oriented) store that doesn't leak its storage schema to users, and doesn't make it hard to grow its domain schema and run arbitrary queries.

Our short-term goal is to build a system that, as the basis for a User Agent Service, can support multiple [Tofino](https://github.com/mozilla/tofino) UX experiments without having a storage engineer do significant data migration, schema work, or revving of special-purpose endpoints.

Datomish is designed for embedding, initially in an Electron app ([Tofino](https://github.com/mozilla/tofino)). It is less concerned with exposing consistent database states outside transaction boundaries, because that's less important here, and dropping some of these requirements allows us to leverage SQLite itself.

SQLite is a traditional SQL database in most respects: schemas conflate semantic, structural, and datatype concerns; the main interface with the database is human-first textual queries; sparse and graph-structured data are 'unnatural', if not always inefficient; experimenting with and evolving data models are error-prone and complicated activities; and so on.
