Rapyd is a PHP5 minimalistic framework made to build applications based on CRUD (Create, Read, Update, Delete) pattern. It provides a set of components / classes that can help you to develop web applications "rapidly".
Its syntax is simple, oriented to build simple Data GUI in few line of code.
It's tiny (≈50 files) and inobtrusive (no conflicts, no notices, etc..).
Backends, Intranets and Administrative Areas need an application framework to manage forms, filters, data grids.
Rapyd can be a lightweight solution, even if you already use a framework, just include it.
