A lovely Saturday:
A perfect day for some refreshment:
Why? (And, why now?) Relational databases and SQL have been around for forty years. Yet, no reasonable business person would disagree that:
1. it's useful to know how to use spreadsheet software, both to DIY and manage others who do;
2. there's much more information out there today;
3. harnessing this information is not only advantageous but essential;
4. more powerful tools like database management systems are necessary for this.
Therefore, business people should know a little bit about these more powerful tools, to continue to be considered reasonable.
