WebRock88 is a compact framework for database-backed web-based applications.
"88" acts as logical separator in WebRock concept and could be read as "at". Underscore cannot be used as it is already widely used in table-, field- and variable names. All other symbols could create problems in auto-generated client-side scripts, etc.
Avoiding "88" in names is the only limitation WebRock as a platform gives you.
WebRock is designed to equally support building new solutions and taking over legacy non-platform or "mis-platform" applications.
