Datomic was created in 2012 by Rich Hickey and the company Cognitect. It was developed to address the limitations of traditional databases in handling immutable data and providing a clear audit trail. The goal was to separate transaction processing from queries, ensuring scalability and flexibility for applications requiring complex queries and historical data analysis.
Datomic
Datomic is a distributed database system designed to enable scalable, flexible, and intelligent applications. It separates transaction processing from queries, allowing it to handle a large volume of reads efficiently. Datomic stores immutable data, providing a time-based model that maintains historical data and supports complex queries with ACID transactions. It is particularly suited for applications requiring a clear audit trail and temporal data analysis.
