Alternative Methods for News Integration
There are 3 main alternative methods to insert news into web applications:
Static HTML
An HTML file is created for application news. HTML is written directly using any text editor or specialized HTML editor may be used. The file is added to a web application or served from other web server.
This is probably one of the most widely used approaches and at the same time the worst one. Why is it used so often if it is so bad? Because initial expense is very low. The problem is that using this method you end up with a system where it is difficult to publish news or update page design and thus news page is always out-of-date.
Old news and outdated page design. It is better to have no news in your application at all.
General-Purpose CMS
Thousands of general-purpose CMS are available on the market. Usually they are designed to maintain a web site or a blog. Some of them are very sophisticated systems with many many features and options. A good starting point to choose a general-purpose CMS is www.opensourcecms.com.
How much can a good general-purpose CMS do? Everything. Isn't "everything" too much for publishing news inside your web application? Definitely.
To install an average CMS you will need to set up an SQL database, clean up interface so a person writing news will not get lost in a myriads of features. You will also need to adjust news page design so it fits your application.
Home-Made System
You may implement a CMS yourself. You are free to implement any feature you may need. CMS may be integrated into your application from the beginning.
If your CMS is integrated into your web application then you will not have any design or other integration issues.
It may take a day to implement a very easy CMS. It may take a year to implement a more complicated one. You must know which features you really need. Each software product has bugs. From time to time you will need a new feature. At the end the effort invested into your own news management system will add up to the significant expense.
My advise - don't count on implementing your own CMS in a day.
