  • We are proud to introduce NoSQLz, a new DBMS on z/OS.

    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 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 control, timestamp-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.

    The version 1 of the product is issued as freeware (for a monoplex); only the full Sysplex version will be chargeable.

    In the full Sysplex version (v2), tables are designed for multiple concurrent access natively throughout the sysplex, with no need for VSAM record-level sharing (RLS) support in the sysplex, nor for any specific coupling or locking mechanism; only a minimal implementation of a sysplex will be required.

    Usages: big data; highly-available data; data warehousing; document store; Internet applications; OLAP; quick alternative to existing relational DBMSs; etc.
