Duct database.datalog

Protocol methods for accessing Datomic-flavored databases.

Installation

Add the following dependency to your deps.edn file:

org.duct-framework/database.datalog {:mvn/version "0.2.0"}

Or to your Leiningen project file:

[org.duct-framework/database.datalog "0.2.0"]

Usage

A Datomic-flavored database connection should satisfy the Connection protocol:

(extend-type SomeConnection
  duct.database.datalog/Connection
  (-db [conn] ...)                 ;; return the database
  (-transact! [conn tx-data] ...)) ;; write transaction

The database instance, returned by -db, should satisfy the Database protocol:

(extend-type SomeDatabase
  duct.database.datalog/Database
  (-q [conn query inputs]))        ;; query the database

This simplified interface does not capture all the nuances and functionality of the databases it wraps, but it does allow for simple queries and transactions to be made.
