Thanks, for the understanding and a good review. I am always trying to put ideas in my article and present one of the ways to make the task done. Unfortunately, very often I got 4-5 stars for the very simple articles and 3 stars for the articles where process flow, methodology, and architectural decisions are required. I think where many database developers and DBAs have difficulties is proper methodology. You can always replace one SQL statement with another one or one stored procedure code with another code. But it is so difficult maintain ETL processes when they do not have proper methodology and made just to be working without thoughts for the future. Thanks again
