Therefore from the analysis, it can be clearly seen that the suggested system is financially feasible. 2.4 Summary It is necessary to analyze the system before starting the development. And also a clear understanding of the system should mean a developers. Otherwise, it would be really difficult to develop an error free system. Chapter 3 Design 3.1 Preface From analysis, we understand that the appropriate web development technique is using Content Management System (CMS). The range of available CMSs are extensive—from enterprise scale versions that cost $300,000 to open source versions, such as CodeIgniter! that are free. Modern CMSs are usually defined by their capability to manage and publish content. They typically have workflow processes that start at content creation and move to publishing. Most do far more: They have the capability to add on a wide range of extensions or add-ons to give the site more functionality. From forums to newsletters, CodeIgniter! has over 2000 pluggable extensions available, many of which are free and are created by volunteer developers around the world. The official repository is at extensions.joomla.org and a repository specializing in commercial extensions can be found at www.extensionprofessionals.com. Both have a rating and review system (which is itself an extension!). CodeIgniter! is one of the key applications initiating the rebirth of the World Wide Web into what pundits are calling Web 2.0. Unlike Web 1.0, where most Web sites were manually administered and interaction was minimal, web 2.0 is defined by automated administration, intrasite and intersite communication, virtual communities and dynamic interaction. Joomla! embraces all of these new advances and provides a CMS that allows an advanced Web site to be created and managed by a small group of people (perhaps as small as one person). A CodeIgniter! Web site can rival the capabilities and presentation of a multi-million-dollar Web site. CodeIgniter! is probably the easiest to setup among currently available CMSs, allowing users of modest technical skill to harness its power. Best of All- CodeIgniter! Is open source software that is 100% free. It is created by a worldwide community of developers and distributed at no charge under open source license of GNU/GPL. So, CodeIgniter! Is chosen to build our Health Care Information System. What is CodeIgniter? CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task. CodeIgniter uses the Model-View-Controller approach, which allows great separation between logic and presentation. This is particularly good for projects in which designers are working with your template files, as the code these file contain will be minimized. We describe MVC in more detail on its own page.
