The concept of an External Transaction Three (EXT3) has been gaining traction in recent years. It is a framework that provides users with a powerful and reliable system for processing multiple, concurrent transactions over the internet. EXT3 uses the ACID-compliant three-phase commit protocol to manage the transaction process.

To unpack, EXT3 is an application that uses a three-phase commit protocol that controls the order in which transactions take place, guaranteeing that they are atomic. It also uses a write-ahead logging facility to maintain the stored data, as well as a recovery process to restore any irrecoverable damaged or corrupt data.

EXT3 is designed to be used in a variety of different businesses and organizations, whether large or small. For small businesses, it can provide a robust platform for processing transactions, while larger enterprises can use it to ensure reliability, scalability, and availability. For both types of organizations, EXT3 is an affordable and efficient way to manage multiple transactions at once.

At its core, EXT3 includes a number of components. First, there is a client application, which is responsible for initiating and controlling the transaction and sending commands to the server. The server acts as the centralized controller, receiving commands from the client and managing the execution of the transaction. The database supports the client and server by recording and storing the changes that are made during the transaction, and by reading and writing data to and from the storage device. Finally, the recovery process is responsible for restoring the database in case of a crash or other failure.

EXT3 works by utilizing the ACID-compliant three-phase commit protocol, which consists of the following steps: Prepare, Commit, and Finish. During the Prepare phase, the transaction is marked as being in progress, and the client sends an extension request to the server. This request includes the details of the transaction and any associated information. The server then verifies that the transaction is valid and logs the details before responding with an OK status.

During the Commit phase, the server sends a commit message to each participant in the transaction, confirming that the transaction should take place. At this point, each participant makes the necessary changes to their systems and sends an ‘ack’ message back to the server. Once all the necessary acknowledgements have been received, the server sends a ‘complete’ message to each participant, signalling that the transaction has finished.

Finally, in the Finish stage, the server deletes the transaction log entry and releases the resources used by the transaction. Once a transaction has been completed, all the changes made to the data are permanent, and the system is now ready for the next transaction. This whole process is designed to ensure that the order of the transactions is maintained correctly, so that no transactions are executed out of order.

EXT3 is a robust and dependable system for conducting a variety of transactions over the internet. It is reliable, scalable, and affordable, making it the perfect choice for a variety of businesses and organizations. With a few simple steps, EXT3 provides an efficient and reliable way to manage concurrent transactions.
