AtomicDB is an associative database. Compared with relational database, associative model stores items (objects) and links (associations). AtomicDB manages associations, not the data. Therefore, every unique instance is stored only once. "At the low level it is a network. At the high level it is a graph."
[Atomic Information Systems](https://www.linkedin.com/company/atomic-information-systems/about/), founded in 2015, owns all trademarks and copyrights to 'AtomicDB'. However, founded in 2011, [Atomic Database Corp](https://www.linkedin.com/company/atomicdb-corp/about/) is the creator of this database. Jean Michel Letennier ([LinkedIn](https://www.linkedin.com/in/jean-michel-letennier-25258a/)) is the founder and CEO of Atomic Information Systems. He posted several [video materials](https://www.aisys.us/Resource-video.html) introducing AtomicDB. The last video was posted 2 years ago. Currently, it's hard to find any news about this database or company. The demo page of one of the listed products, [AtomicDBOnline](https://www.aisys.us/adbo.html), is not accessible at the time of writing.
In [introduction video](https://youtu.be/cU-BD57vRlc?t=1592), developer introduces 6 API, claiming the learning curve is 2 weeks. However, [homepage](https://www.aisys.us/index.html) states 7 API calls. "No query language, just 7 API calls to access and manage data."
