A Sample Staging tables volumetric worksheet

A sample table volumetric worksheet from the ETL Toolkit focusing on the final delivery tables at the end of the ETL data flow.

A full volumetric tracking system would have similar worksheets for copies of source data and the staging files that followed the cleaning and conforming steps.


The volumetric worksheet lists each table in the staging area with the
following information:




The staging area normally consists of both DBMS tables and flat text files on the file system. Can we use flat files for staging. Yes. Flat files are especially important when using a dedicated ETL tool. Most of the tools utilize an area in the file system for placing data down to optimize its workflow. In many cases, you need to stage your data outside of a DBMS in flat files for fast sequential processing. You can also use the volumetric
worksheet for file-system planning.
