Here is NoSQLZ database for Mainframe

NOSQLZ DBMS – Freeware Product. It enables you to manage key-value schema-less tables; data is “format-agnostic”. NoSQLz can be used through function calls in application programs written in COBOL, assembler, REXX, etc.

NoSQLZ Database

NoSQLz belongs to the NoSQL system family. Only basic CRUD functions (create, read, update, delete) are provided. It is designed to be very straightforward and easy to implement.

ACID properties are provided, so as to have “real transactions”, through optimistic concurrency controltimestamp-based concurrency control and multiversion concurrency control (MVCC); retrieval is always favored, at the (possible) expense of updates.

Record size varies from 500 bytes (minimum) to 75 MB (large records supported). There can be up to approximately 1,000,000,000 records in a single table.
