OLE DB Source

An OLE DB Source is a component used in data integration and ETL (Extract, Transform, Load) processes to connect to a database or data source. It retrieves data from various systems—like SQL Server, Oracle, or Excel—that support OLE DB (Object Linking and Embedding, Database) technology. Essentially, it acts as a bridge, allowing a data workflow to access and extract data efficiently from different sources, enabling further processing or analysis downstream in the data pipeline.
