Content management system (CMS) - engine of a site allowing to operate textual and graphical content of a site, that is to change information on a site not caring about the internal mechanism of construction and output of web-pages. Some kinds of sites are extremely hard support without content management system.
Ever since the dot com era has seen a boom, HTML has been an integral part of producing readable formats to web page viewers. I was a good programmer when I was young, loved to write for our favorite Visual basic and Java… but then while the concept of ecommerce started I was dumbstruck to find what Internet could do. It was, a new form of media, entertainment and advertisements.
As and as sites grew, so grew the competition. Sites grew enormous and contents were huge. Think of it as National Library without any management. Now people (probably the best minds in business) had to plan. Before planning a business must there be a plan…. about how easy a site can be managed.
