ABOUT RUBY ON RAILS

The Ideals of Ruby’s Creator [source: http://www.ruby-lang.org/en/about/] Ruby is a language of careful balance. Its creator, Yukihiro “matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Building on this, he adds: Ruby is simple in appearance, but is very complex inside, just like our human body1. -------------------------------------- Ruby programming language IDE - Netbeans · RubyForge · RadRails · RubyMine · ActiveState_Komodo Implementations - Ruby MRI · YARV · JRuby · IronRuby · Rubinius · XRuby · MacRuby · RubyJS · HotRuby Applications - RubyGems · Rake · Interactive Ruby Shell · Capistrano · SketchUp Ruby Libraries / Frameworks - Adhearsion · Camping · eRuby (RHTML) · Merb · Nitro · RubyCocoa · Ruby on Rails · Sinatra · Ramaze Server Soft

The MySQL Privilege Tables

Before delving into the many examples that consititute this tutorial, a brief introduction of one of the most important (and most misunderstood!) aspects of the MySQL server is in order; that is the mechanism from which MySQL secures its data and integrity: The MySQL privilege tables. The MySQL privilege tables are responsible for authenticating user access to the MySQL server, and subsequently associating those users granted access with a set of privileges. This privilege set decides what a user is capable of doing while connected to the MySQL server, controlling the user's activities on a server-wide, database, tabular and even columnar level. For example, an administrator could grant a user only enough privileges to connect to one specific MySQL database, and restrict access to all others. Furthermore, that same user might be granted only certain privileges while connected to that database, selection, insertion, and modification privileges for example. Associated with only these
