What is a CMS A Content Management System (CMS) allows you to edit the content of your website / homepage with a browser alone, ie without the need to install additional software. Web pages are stored internally in the so-called HTML, or more recently in XHTML format. This can be edited with a simple text editor, and in fact I have developed in 1995, my first website with Notepad. Later, there were specialized HTML editors such as Dreamweaver or Frontpage, which had to be purchased and installed. If you are a technical hobbyist and create their website from the ground to update itself and so you can use an HTML editor. If you want to worry only about the content and special applications such as a newsletter or a RSS news management system want, then you are better off with a CMS and a suitable solution provider. What CMS There are commercial CMS, you can buy and develop themselves, where you have no choice in the solution provider. Keep the hands off and put on an open source CMS.The best among them like Typo3 or Joomla are practically equal to the commercial. Both are very popular – there are 2 million German-language sites Typo3 and Joomla 1.7 million pages. There are a large number of solution providers, what you put in a fortunate position to change the partner, if you are not satisfied. Coordinated Typo3 TYPO3 is a popular open source CMS, its dissemination and development of the TYPO3 Association is. About 100 volunteers are working on the development and currently there is in addition to the core CMS hundreds of application modules.
