An information system is any combination of information technology and people's activities using that technology to support operations, management, and decision-making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, algorithmic processes, data and technology. In this sense, the term is used to refer not only to the information and communication technology an organization uses, but also to the way in which people interact with this technology in support of business processes.

The collected information could be in any number of formats (electronic, printed, graphic, audio, statistical, combinations). There are physical (paper/print) and electronic databases. A database could be as simple as an alphabetical arrangement of names in an address book or as complex as a database that provides information in a combination of formats.

Web based applications have evolved significantly over recent years and with the improvements in security and technology, there are plenty of scenarios where traditional software based applications and systems could be improved by migrating them to a web based application.

Typically the minimum requirement would be a web browser of which there are many. These web browsers are available for a multitude of operating systems and so whether you use Windows, Linux or Mac OS you can still run the web application. It is also more manageable. Web based systems need only be installed on the server placing minimal requirements on the end user workstation. This makes maintaining and updating the system much simpler as usually it can all be done on the server. Any client updates can be deployed via the web server with relative ease. Another benefit is it is highly deployable. Due to the manageability and cross platform support deploying web applications to the end user is far easier. They are also ideal where bandwidth is limited and the system and data is remote to the user. At their most deployable you simply need to send the user a website address to log in to and provide them with internet access. This has huge implications allowing you to widen access to your systems, streamline processes and improve relationships by providing more of your costumers, suppliers and third parties with access to your systems. Next is secured live data. Typically in larger more complex systems data is stored and moved around separate systems and data sources. In web based systems these systems and...
