Applications Area of Distributed Transactions

What is the Need For Distributed Transaction?

Some properties are harder to implement, that cannot be implemented with simple transactions. Many times basic single-system techniques are not sufficient. Distributed transactions are required when there is a need to quickly update data that is related and spread across the multiple databases or nodes connected in a network....

Working of Distributed Transactions

The working of Distributed Transactions is the same as that of simple transactions but the challenge is to implement them upon multiple databases. Due to the use of multiple nodes or database systems, there arises certain problems such as network failure, to maintain the availability of extra hardware servers and database servers. For a successful distributed transaction the available resources are coordinated by transaction managers....

Advantages of Distributed Transactions

Data Consistency: Data Consistency is being provided across multiple resources by distributed transactions. Various Operations are being coordinated across multiple database resources. This makes sure that system remains in a consistent state even in case of any type of failure. Fault Tolerance: Distributed systems can handle faults and ensure proper transactions. If the participating resource fails during the execution of the transaction the transaction can be then rolled back on alternate resources and completed successfully. Guarantees Transactions: Distributed systems guarantee the transaction. It provides features such as durability and isolation. The durability makes sure that if any transaction is committed, the changes last even if any failures occur....

Applications Area of Distributed Transactions

Enterprise Resource Planning (ERP) Systems: ERP systems consist of departments within one organization. Therefore distributed transactions are used here in order to maintain transactions from various modules such as sales, inventory, finance, and human resources management. Cloud Computing: Distributed transactions are being used in cloud-based applications. Transactions can be done with the help of multiple data sources and ensure that data updates and operations that are performed consistently. Healthcare Systems: Healthcare systems make use of Distributed transactions when coordinating patient records, scheduling appointments for patients, and managing the billing systems. Distributed transactions maintain data consistency and performance in healthcare systems....

Conclusion

Distributed transactions are used when multiple resources such as repositories or database systems are used in order to perform the transaction. Distributed transactions provide various benefits such as data consistency, guarantees transaction, and improve the overall performance and scalability of the system. Therefore distributed transactions are being used in various applications in order to gain the above benefits....
