Many organizations build system-of-record applications with ledger-like functionality because they want to maintain an accurate history of their application data. However, ledger applications are usually implemented using relational databases, making building audit functionality with relational databases time consuming, prone to human error, and requiring custom development. This led us to build the world’s first fully managed ledger database, Amazon Quantum Ledger Database (Amazon QLDB). Amazon QLDB is a new class of database that provides a transparent, immutable, and cryptographically verifiable transaction log. Come to this session to learn about the features and functionality of Amazon QLDB, and see a live demo.
