µq is an in-memory soon-to-be temporal database inspired by
Datomic.
Run lein cljsbuild once default and then open muq.html in your browser.
Alternatively, have a look in the queries in src/learn_datalog_today.clj.
- by accident: it was surprisingly easy/straightforward to write a query engine with features similar to datomic (making it fast and/or implementing immutable index/database trees proves to be much harder)
- curiosity: to discover how datomic works
- different use cases: wanted to use datomic on the client
- future ideas:
- no schema
- embeddable (similar to sqlite, one-file db, probably not in clojure then)
- not relevant anymore: survive laptop restarts (fixed by datomic 0.9.4899)
- actually put some data in it (e.g. run on node, serialize to EDN/..., have a tiny transactor-like thing, allow querying for time)
- a comprehensive set of queries
- think about a better index
- on-disk storage, preferably in a key-value store (e.g.
localStorage) - support the schema
- ...
- quantified self
- making interaction data explorable (making asking questions about ones own activities easier, allow storage of loosely structured, interlinked data about documents on the web)
- as an ai in games (not for something like pathfinding, but for asking questions about the game world and other entities in it. "where can i buy X, which nearby system has an occurrence of Y?" but that requires a bit more thought, most likely something custom-made fits better.)
