What does Online Data Processing (OLDP) manage?

Online Data Processing (OLDP) is designed to handle data in real time rather than in batches or through other methods. This means that OLDP systems are actively receiving and processing data as it comes in, allowing for immediate data entry, analysis, and response. This capability is essential for applications that require up-to-the-minute information, such as financial transactions, ticket reservations, or order processing systems, which demand timely interaction and results.

In contrast, other methods like batch processing, which gathers and processes data during idle periods, do not fit the definition of OLDP, as they involve delays and are not suited for applications that require immediate action. Similarly, while the management of data from multiple independent sources may occur in various processing systems, it does not specifically define OLDP. Lastly, stored data processing refers to operations executed on previously collected data rather than the immediate handling of data as it is generated or received. Hence, B accurately characterizes the functionality and purpose of Online Data Processing.
