In DB Delta mode, what parameters must you use?

• A. currentExportDateTime or previousExportDateTime
• B. lastExportDateTime or currentExportDateTime
• C. startDateTime or endDateTime
• D. previousExportDateTime or recordID

Answer: (B)

When working with DB Delta mode in a data integration scenario, the parameters that are crucial to effectively capture the changes or differences in data are the timestamps that indicate when the last data export occurred. The use of lastExportDateTime and currentExportDateTime is essential because: - lastExportDateTime refers to the timestamp of the most recent export, allowing the system to identify and compare which records have changed since that last export. - currentExportDateTime indicates the time of the current export, establishing a new point of reference in the data comparison. Together, these parameters enable the identification of newly created, modified, or deleted records since the last export, ensuring that the synchronization between systems is accurate and up-to-date. This capability is critical in a delta processing context, as it allows efficient data updates without needing to re-fetch all records, thereby optimizing performance. Understanding these parameters is key to effectively leveraging the DB Delta mode for incremental data loading, which is a common practice in data integration workflows.
