Predictability

This section could just as well have been titled "standards compliance," but I decided against it because the benefits of standards compliance in corporate projects are not obvious. The limitations of the common databases are well documented, and I will show you a few websites in a moment where you can make a comparison of who has the most "unintended behavior". I encourage you to read the material while thinking to yourself about the question, "Which method of feature development is most likely to make my application break in the future?"

Spoiler alert: Stricter adherence to standards comes at the cost of not allowing ambiguous behavior. Not allowing ambiguous behavior makes the developer's life more difficult. Making the developer's life more difficult ensures that the interpretation of the commands that the developer gives will not change later, breaking the application.

Just how...
