I love to help move data from random sources to aha moments. Which wonвЂ™t impress your DBA.Дata is my jam. But at the end of it all, querying system tables and eyeballing the results is about the best way I know to be sure you donвЂ™t leave a bot trying to calculate cardinality between a couple of poorly indexed multi million row fact table without key definitions. There are reasons for variances.ДЄnd there are tools like Erwin, Toad, DbVisualizer and the marvellous DBDesigner (open source) that can make short work of visualising the structures. Data is never вЂњcleanвЂќ, but then itвЂ™s also never вЂњdirtyвЂќ. Sure, there are tools like SAPвЂ™s Information Steward, SQL Data Quality Server, or ex Google now open source OpenRefine than can analyse data and clue you in to data content. Manually? Not sure what is meant by that. I was also asked what tool could be used to reverse engineer a database вЂњbecause doing it manually wonвЂ™t workвЂќ. Of the more than a thousand databases I have worked on, I can think of less than 10 occasions where an ER diagram was forthcoming.

It is very rare that we find a database ER diagram waiting for us, and an up to date one rarer still.

Noticed I was an experienced end-to-end business intelligence consultant. I wondered if he has had a chance to look at my LinkedIn profile. On three separate occasions this week I was asked if I had experience reverse engineering a database as there was no metadata or ER diagram kept.
