One of the most common types of interactive or dynamic web pages is the database driven type. This means that you have a web page that grabs information from a database (the web page is connected to the database by programming,) and inserts that information into the web page each times it is loaded. If the information stored in the database changes, the web page connected to the database will also change accordingly (and automatically,) without human intervention. Because of such procedure, the number of files for constructing the entire website can be reduced. This is absolutely conducive to space and bandwidth saving.
In addition, an interactive online system acts like a human being and able to work for you round-the-clock since it is an automated system. It can be pre-programmed to serve your existing customers and potential customers, to manage myriad of things without your direct operation. It is overwhelmingly appealing to web surfers as it has dramatically expanded with the growth of the World Wide Web, always accessible and absolutely accommodates the special needs of majority and minority groups. Such a tremendous versatility is one of the most outstanding elements of an interactive online system.
