A Content Management System (CMS) is that which is used to manage the creation, editing, reviewing, indexing, searching, as well as publishing of various information or interactive features that are useful to the end-user. In Internet parlance, this usually refers to everything concerned with managing content on a website.
CMS usually functions as an interface between the user producing the content, and the person viewing it. For example, a writer trying to bounce ideas off the public for his latest novel will not be expected to know the intricacies of the programming that goes behind publishing his work on a website. In this case, an intermediate application may be used to make things convenient for the author to publish his thoughts and ideas, thus making things easier.
Let us run with the same example and look at some other features of a CMS. Suppose there were fifty authors publishing their work on a single website, and one of them suddenly decides to look at her past work. It would be tedious and time consuming to wade through the database and look for her work amongst several other stories. Using a CMS, she could simply search for her name, a specific keyword, or perhaps the date of creation of her work, and the CMS would display the appropriate article that she was looking for.
A CMS is usually clubbed with a template that the application is compatible with, and provides for a Graphical User Interface (GUI) to make things simpler for the user creating the content. To understand this, compare the ease of use when concerning operating systems like Windows and MS-DOS.
In Windows, the user would only have to press the delete button on the keyboard followed by the enter key to remove a piece of data. But in an operating system like MS-DOS, the user will have to enter the required command (in this case, the DEL command) followed by the filename to delete the data that is no longer required. While it is arguable that one command can be committed to memory, consider a system that has hundreds of commands that are used to perform various operations on a daily basis. This is where a GUI of a CMS would score over other types of applications.
The advantages of using a CMS are there for all to see, and it has helped shape the future of database management and its various applications on the Internet.
Most used CMS are Wordpress and Joomla, because they are easy to use and there are lots of site like wordpress developer and joomla template with lots of content free to use
