A fast and affordable solution that is scalable and has a nice dashboard
The product enables the users to query results faster. It maintains all the versions of the changes done on a specific node. A traditional blockchain would take time, but Amazon QLDB is a bit faster. We have to do many operations in blockchain to read data, but QLDB comes with an easy syntax. The product provides a nice dashboard to view all the information.

Adapting to changing data needs with reduced development time and schema flexibility
Amazon SimpleDB is beneficial to me due to its reduced development time, adaptability, improved agility, and its ability to handle unstructured data. It also offers schema flexibility, which aids me in documentation, version control, modular design, data normalization, and denormalization. With this, I have a clear understanding of the data, considering future challenges, and designing for expansion.
