Explain what is ods (operation data source)?
Answer / Omprakash Meena
An Operational Data Store (ODS) is a centralized repository that stores operational data from various transactional systems in an organization. It is used to support operational reporting and analysis by providing a single, consistent view of the data. Unlike a Data Warehouse, which is designed for complex analysis, an ODS is optimized for speed and is typically updated in near real-time. An ODS can be considered as a bridge between transactional systems and the Data Warehouse.
