What Is Transaction Manager?

They say, "The best things in life are worth waiting for." what if you're waiting for a transaction to complete? Tricky business, right? You want to ensure that once the transaction is started, it will complete,d you don't have to wait around all day for it to finish. That's where the transaction manager comes in. The transaction manager is like a traffic cop: it manages the coordination of transactions over one or more resources. It creates transaction objects and contains their durability and atomicity. The transaction manager keeps track of all the resource managers enlisted in a transaction so that the rest can continue safely when one resource manager fails. A transaction manager coordinates with these resource managers to ensure the marketing is durable, meaning it can be recovered even if it fails. The transaction manager also provides that once the transaction has been committed, it cannot be rolled back by another process or user. Transactions are always atomic, meaning they either succeed ultimately or fail altogether. Examples of transaction manager use cases include: Booking a trip, Transferring money between two accounts, Booking a hotel room, and Purchasing goods from an e-commerce site. Each scenario may involve multiple steps, and different parties may be affected. For example, let's say you want to book a trip. You may start by searching for desired dates and locations. It would be the equivalent of searching for desired rates in the first step. Once you have found the correct date and place, you may decide to pay for the trip by booking it. It would be the equivalent of finding the right rate in the second step. Transaction managers are the unsung heroes of your company's business. They manage transactions and make sure they run smoothly. If you need a transaction manager, it's like having a ballet company without a dancer in the lead role. You're just going to get only part of the experience.
