A Technical Mind is a Useful Mind
I taught myself MS Access and used it daily for four years to create and reshape databases for CPS Security Solutions. I'm a little obsessed with the possibilities of affordable relational database applications. My husband and I frequently go over MS Access solutions for fun.
PHP is an application that uses relational databases brilliantly, allowing the client to change the content of a web page easily without touching the design elements. It is what Content Management Systems (CMS) and Learning Management Systems (LMS)are based in, like Moodle, Joomla, Drupal and Wordpress.
Most of my work will use a Content Management System as I find them to be the most practical, versatile, affordable and future-thinking.
