Why it is good requirements analyst have technical background or why all databases are casesensitive.

We are lucky! Requirements analyst in our project is a girl with technical background. Once she admit to me that she was a developer for a 5 years. What a relief. No more unrealistic requirements based on assumptions of people from marketing department, right?

As usual during project life cycle database schema changed. Well it was not actually a schema. Just the rule that user identifier change to case sensitive. This trigger a discussion what changes needs to be applied to the application to handle that change. One of the issues was is it necessary to update db queries. And this was the moment I appreciate that our requirements analyst had deep technical understanding. She just explain to everybody

girl : "There should be no change in a way we handle database. For sure it is case sensitive , its obvious that ASCII code of 'a' is different from 'A' , we do not need to take care about it ..."
