DW Architecture: The Streamed Data Repository

April 11, 2013

As specified in the DW Architecture block diagram, the Streamed Data Repository (SDR) belongs to the Data Warehouse Architecture.

The discrete data generated by the Streamed Data Management System (SDMS) is stored in the SDR as periodic snapshot fact tables and its associated dimensions. This fact tables are predictable dense and can get large. Further reduction can be done by aggregation.

The feeds from the SMDA are received in semi real time; depending on the nature of the streamed data, the rows (grain) in the fact tables can be mapped to one of more time windows on the SDMS.

The data in the SDR is normally used for long time observations or thread identification and analysis. The data in the SDMS is used for real time monitoring.
