Relational Database Management Systems - RDBMS
A static website is the simplest type of website to build but it is often the most costly to maintain. In a static site, website content is integrated into each and every HTML page. If there is a need to change the content, the web page content must be changed and the page re-published.
Frequently, there is a need to display essentially the same content on multiple pages in a web. For example, a list of products and services might be shown alphabetically on one page and grouped into categories on other.
Should the price of a product or service change, it is then necessary to update each page where that product or service appears and to re-publish those pages. Not only is this a labor intensive process, it is also error prone.
