1. UniData, UniVerse :
It is a MultiValue database and application server with SQL mapping layer and meta database capabilities. UniData makes for easier database design, eliminating the constraints of SQL normalization. UniVerse is a component of the MultiValue application platform, Its advantages is fast, flexible data server for developing enterprise apps. UniVerse-based applications maximizing processing throughput of available resources, dynamically allocate available resources.
2. VoltDB :
It is distributed In-Memory NewSQL RDBMS and an ACID-compliant RDBMS that uses a shared nothing architecture. This database designed by Michael Stonebraker, Sam Madden, and Daniel Abadi. Initially VoltDB database includes graphs for cluster throughput and latency as well as CPU and memory usage. VoltDB is based on H-Store and scales with the increasing core-per-CPU counts on multi-core servers
