Then if anyone ever asks what changed, you just refer to the log and your done. The ETL process is an iterative process that is repeated as new data is added to the warehouse. I would always record how many records were read, how many records were updated/inserted, reported exceptions, etc. Oracle E-Business Suite (EBS) is a set of business applications for managing and automating processes across your organization. Granted, it requires more effort to program it to do this and make sure exceptions are handled properly, but it’s the cleanest and easiest way to know exactly what happened during a process. In this phase, a separate schema on the data warehouse database is maintained as a replication of the source transactional systems’ tables, deletes, as well as additional optimizations for incremental ETL. SDS stands for Source Dependent Data Store. What I’ve always done is make log files/tables during these types of programs, that way if you ever want to know what changed, then you have it all in one place. Oracle BI Applications ETL processes includes these phases: SDS, Health Check, SDE, SIL, and PLP. ![]() Generally speaking tho, I always found it easiest to keep a record of the changes in the actually conversion program (in your case an ETL program). On a side note, there’s really not much to suggest here, since we don’t know exactly what you want to compare, and how much data you are talking about comparing, etc. Data is collected from one or more data sources. Here’s a quick summary: Extract Extraction is the first phase of extract, transform, load. ![]() This could be a database, data warehouse, data store or data lake. As John mentioned, you could try using Compare Data and/or Schema Compare, and with that you might look at using Automation Designer to automate the tasks if you find those work for you (there’s a ton of documentation on Automation Designer on Toad World and in the Help). The ETL Process Explained ETL moves data in three distinct steps from one or more sources to another destination.
