FoundationDB, a developer of transactional NoSQL database software that resolves ACID, has raised $17 million in Series A funding. ACID (Atomicity, Consistency, Isolation, Durability), a set of properties that guarantee that database transactions are processed reliably, is a touchstone for any NoSQL database and a major obstacle in non-relational database software becoming mainstream, according to market study NoSQL Market Forecast 2013-2018. Resolving ACID is a Holy Graal of NoSQL movement and many aspiring startups have broken their lances trying to achieve ACID levels on a par with relational databases.
