Thank you, that is a nice overview to reference when coming up against a daunting task like this. I did want to throw one tool into the mix that has been a great addition to my arsenal. The Case/ERD tool Toad Data Modeler handles the nicest mix of features without breaking the bank. It was originally named Case Studio and then purchased by Quest, albeit with a price increase to boot. It now costs about $479 (~$450 at Programmers Paradise), but far less expensive than most other tools with similar capabilities like ER/Win. Data Modeler handles the majority of tasks in your article, while also providing other nice features like column, table and object notes and comments that can be printed as part of your data dictionary, which also show when hovering over the object diagram.

Also, I like the idea about colored rectangles to group related tables. Using Data Modeler, I color the tables by group and group them visually in a similar area, as much as possible, while also providing a legend in each area to denote what each color represents.

Once again, thank you for you contribution,
Tom

Excellent summary and I agree with it all.

You should do articles on each individual point with examples.

Thanks,

ERStudio from Embarcadero is your friend when you have complex data models!

I agree with theSQLGuru - ERStudio can be very helpful in larger models. I am curious why you focus on the big table(s) and the one(s) that are most frequently used. I could see this as being important for space and archiving concerns, but for business logic I would walk the foreign keys and study the procedures. It would be interesting to hear from you in a future article about what kinds of problems your methodology has solved.

Hello,

I can assure you that my article came first, since I did a lot of research before posting it here and found nothing similar. You can check that by the data of the post, since to publish articles here in SQLServercentral.com you have to wait the approval of the administration. It's very sad that nowadays you can see a complete copy of your work without authorization and even a simple reference.

Well, I can tell you Mauro showed me his article in January/2011 if that helps you find an answer Smile

BTW, nice article, Mauro!
