Service: Amazon Quantum Ledger Database (QLDB)
Answer:
Amazon QLDB supports a flexible data model that can be used to store any type of data in tables. The data model is based on a transactional model, meaning that every change to the data is recorded as a transaction.
QLDB supports an SQL-like query language called PartiQL, which is designed to be compatible with both SQL and NoSQL databases. This makes it easy for developers to query data in QLDB using familiar SQL commands.
In addition to PartiQL, QLDB also supports the ability to use the Amazon QLDB Driver for Java, which allows developers to query and interact with QLDB using the Java programming language. The driver provides a simple and intuitive way to interact with QLDB, and makes it easy to build scalable, high-performance applications that use QLDB as a data store.
