NoSQLz
NoSQLz is a consistent key-value big data store for z/OS IBM systems. It was developed by systems programmer Thierry Falissard in 2013. The purpose was to provide a low-cost alternative to all proprietary mainframe DBMS.
NoSQLz is proprietary software. Version 1 is freeware.
Distinctive features
NoSQLz only provides basic create, read, update and delete functions. It is designed to be very straightforward and easy to implement.ACID properties are provided, so as to have "real transactions", through optimistic concurrency control, timestamp-based concurrency control and multiversion concurrency control.
