A fast way to load the Staging Area

There are several solutions to load data from a source system into the Staging Area of a Data Warehouse. Usually, either database links or flat files are used to transfer the data between OLTP and DWH databases. But there are other options…

A different, but very interesting approach can be found in the technical white paper Solution for Staging Area in Near Real-Time DWH. Two Trivadis colleagues from Vienna, Karol Hajdu and Mathias Zarick, describe a technical solution based on Oracle Data Guard and Transportable Tablespaces that is very useful for Data Warehouses with high amount of loaded data and short latency requirements. Especially for Near real-time Data Warehousing and Operational Data Stores the solution described in the white paper can be very powerful.
