Guys, I am back. I was out for a while, travelling to east coast of US. So where were we? We talked about data profiling, its need and the approach towards it. Last few days I have gone through a very good, detailed process of supplier normalization, classification, enrichment using a global compendium. I worked with the people in industry who are doing this business since last 25 years and associated with big names in finance, banking, entertainment and packaging. So once you do the data profiling, you come to know the richness (or dirtness) of the data. Based on which you can estimate your efforts. But what if customer already has a good structure of the data (not good data though)? Initial work is easy. Talk to customer about the data format, input columns, totalling, what all things customer wants to see. Once requirements are frozen, you can go to next step setting up an environment in your system for the customer. Test the whole setup using the sample data format from the custome...
