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