What is meant by Transaction processing?
The term "transaction processing" refers to the process of capturing, processing, and managing transactions in information systems. A transaction represents a logical unit consisting of a series of operations that must either fully succeed or completely fail. Transaction processing ensures the integrity and consistency of data in databases, especially in environments where multiple users access the system simultaneously.
Typical software functions in the area of "Transaction Processing":
- Transaction Management: Managing transactions to ensure that all operations within a transaction are either fully executed or rolled back in the event of an error.
- Data Integrity: Ensuring the consistency and accuracy of data during transaction processing.
- Locking Mechanisms: Implementing locking mechanisms to control concurrent access to data by multiple users and prevent conflicts.
- Logging: Recording all transactions in log files to enable data recovery in case of system failures or crashes.
- Rollback Functionality: The ability to reset a transaction when an error occurs, thereby undoing all changes.
- Real-Time Processing: Supporting the processing of transactions in real time to provide immediate results and feedback.
- Reporting: Generating reports on executed transactions, including success and error messages.
