session w/ user roles

Databases are not my thing... I mean I just don't get them. That being said, I have used codeigniter a while ago w/ grocery crud to try to learn this stuff and made something that worked but didn't touch it for a while and forgot everything. What I am trying to build is a log in with sessions where I can assign user rights based on roles. Do any of you know of any tutorials, pluggins, scripts or anything that would help me create this environment? I have found examples of sessions but roles are evading me.

The basic data structure for permissions is

Code:

#
# TABLE STRUCTURE FOR: permission_groups
#

DROP TABLE IF EXISTS `permission_groups`;

CREATE TABLE `permission_groups` (
  `groupID` int(11) NOT NULL AUTO_INCREMENT,
  `groupName` varchar(200) DEFAULT NULL,
  PRIMARY KEY (`groupID`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1;



#
# TABLE STRUCTURE FOR: permission_map
#

DROP TABLE IF EXISTS `permission_map`;

CREATE TABLE `permission_map` (
  `groupID` int(11) NOT NULL DEFAULT '0',
  `permissionID` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`groupID`,`permissionID`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;



#
# TABLE STRUCTURE FOR: permissions
#

DROP TABLE IF EXISTS `permissions`;

CREATE TABLE `permissions` (
  `permissionID` int(11) NOT NULL AUTO_INCREMENT,
  `permission` varchar(200) DEFAULT NULL,
  `order_position` int(11) NOT NULL,
  PRIMARY KEY (`permissionID`)
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1;
