Amazon QLDB

name: Amazon QLDB
description: Amazon Quantum Ledger Database (QLDB) is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log. QLDB tracks each and 
  every application data change and maintains a complete and verifiable history of changes over time, making it ideal for systems of record where data integrity and auditability are critical.

    The Amazon QLDB API provides programmatic access to manage ledger databases
    with immutable, transparent, and cryptographically verifiable transaction
    logs. It enables developers to create and manage ledgers, submit PartiQL
    statements, stream journal data, and export ledger blocks for verification
    and auditing purposes.
