We're mostly using Oracle Data Quality during the ETVL process, or to make sure that there's one source of truth and that there's no redundancy at all. We're also using the solution for quality assurance and data governance. It's part of the cleansing activity for enterprise data, not only for a data warehouse but also for Data Lakehouse. Through Oracle Data Quality, you'll get data from multiple sources, plan it then present it with an analytics layer.
The features I like most about Oracle Data Quality include extraction, transformation, and validation, which makes it a multipurpose product such as Oracle GoldenGate and Oracle Data Integrator.
I also like that Oracle Data Quality is very fast, so you can use it for a large volume of data within a short period.
You have to do the validation very quickly, so the solution helps in that area of data quality.
Another feature of Oracle Data Quality that I like is the MDM (Master Data Management) where you'll have a single source of protection, and this makes the solution perfect and helpful to my company.
