Reading this thread reaffirms some ideas I have had about CMS's and different types of data.
Examples are product catalogs and employee payroll records.
Historically, relational databases have proven robust and speedy at handling this type of data. It should come as no surprise that some CMS's are better for product catalogs than they are for news sites, and vice versa. Relational databases v.s. There aren't any silver bullets, and no one product or technology will magically solve our cms challenges. Course you know this, but they'll still try to sell ya.
