My favorite feature is that once I input the information someone else cannot change it. It locks which is very important because I have had plenty of issues in the past with other softwares that claim I have the locking feature yet somehow someone manages to change something which completely throws off the information. It is important to be able to view information but for someone to not accidentally change something. I also like that it seems easy to manage as my company does not have to deal with the servers themselves. **What do you dislike about Amazon Quantum Ledger Database (QLDB)?** I do wish with banking transactions there was a bit more information and ease of changing or updating the information. **What problems is Amazon Quantum Ledger Database (QLDB) solving and how is that benefiting you?** This has been an easy to manage very helpful analytics tool that gives me the ability to really analyze key data so I can make recommendations ### 2. record transaction history. **Rating:** 4.5/5.0 stars **Reviewed by:** Krishan K. | Mid-Market (51-1000 emp.) **Reviewed Date:** August 24, 2020 **What do you like best about Amazon Quantum Ledger Database (QLDB)?** If you want to make an application in which many financial transactions are taking place every day. So you must have to manage its ledger (like transaction processed or failed if failed whats the reason etc.).
