What Is Amazon Ledger Database? How To Setup Amazon QLDB

A ledger database acts like a digital notebook where accounting records can be stored. Rather than the physical book with leaves, it is a digital software on a computer that keeps track of financial transactions and makes financial information more easy to manage. A Ledger can be used to determine the database under which records likes financial exchanges, such as payments or sales exists. These exchanges feature date, people involved, and the amount of money that was paid.

Earlier database ledger was just a type of record of financial exchange but now they exists in a software on our system which have the inbuilt security measures that include encryption and provision of access rights only to authorized persons so that the user money can be kept safe and other people aren’t able to access their financial details. They are used regularly in many places, for example accountants, bookkeeping professionals, Banks and online stores. They help the user to keep correct and reliable balances of their financial transactions.

What Is Amazon Ledger Database?

Amazon Ledger Database (QLDB) is a well managed ledger database service managed by AWS. It is an Amazon Managed service which provides the creation and management of decentralized databases using a blockchain. It stores data in such a way that it can only be changed or deleted by the admin user who will notice the difference and correct it. However, It is Different from a central authority that is responsible for data, Amazon Ledger Database use a distributed network, which allows multiple parties to confirm and share with the correctness of the documentation.
