What do you mean by ODS (Operational data store)? |
|
Answer» Between the staging area and the Data Warehouse, ODS SERVES as a repository for data. UPON inserting the data into ODS, ODS will load all the data into the EDW (Enterprise data warehouse). The benefits of ODS mainly pertain to business operations, as it presents current, clean data from multiple sources in ONE place. Unlike other databases, an ODS DATABASE is read-only, and customers cannot update it. |
