7 Chapter 2 – Review of Literature and Research Overview of all literature and research sources: Introduction: Woojung Suh, author of the book Web Engineering: Principles and Techniques, states that “since the advent of the Web, every aspect of our lives and organizational activities has changed dramatically” (p. vi). The World Wide Web has become extremely important and has had a significant impact in business where the use of Web technologies has rapidly increased (Standing, 2002; Suh 2005). Many businesses view Web technologies as a vital tool in their day-to-day operations and they have made every effort to expand the development, use and maintenance of Web-based applications (Suh 2005). Expanding on Suh’s view of Web technologies, John Artz (1996) believes that corporate Web applications, specifically those using multimedia hypertext software based on the TCP/IP protocol suite, provide corporations easy access to a multitude of “corporate information resources for internal and external users on a wide variety of platforms in geographically distributed locations” (p. 64). Web Application Technologies: Web applications are built using a number of different technologies that work with each other to produce the desired product. Hassan and Holt (2005), along with Westman (2002), advocate that Web applications are not just made up of static hyper-text markup language (HTML) pages but also include dynamic pages. Suh (2005) expands on this idea defining a Web application as “any application program that runs on the Internet or corporate intranets and extranets” (p. 77). Moreover, Suh (2005) suggests three types
8 of Web applications: static Web documents, interactive Web applications and complex Web-based database systems. Static Web pages are usually written entirely in HTML while dynamic, or active pages, are similar in structure to static pages but are written in languages such as VBScript, Active Server Pages (ASP), Java, JavaScript (Hassan & Holt, 2005), ColdFusion, or PHP (Westman, 2002), which contain active control code. In dynamic Web pages the HTML tags control how the content will be displayed on the users screen while the control code offers more complex functionality, depending on the framework chosen, to determine what to display (Hassan & Holt, 2005; Brooks-Bilson, 2003; McNeil & Robin, 2000). There are numerous frameworks one can use to develop applications for the Web but they all operate in a similar fashion. If a client browser requests a dynamic Web page, that page is preprocessed by the Web server. The control code in the page is executed and the result of the executed code is combined with the HTML tags in the page and the result is displayed to the user’s browser (Hassan & Holt, 2005). According to Chen and Heath (2005) there are five major components to a database backed Web application. Figure 1 shows how these components act together to deliver a dynamically generated Web page. The Web server and application server are often times one and the same, where the Web server runs the software that compiles the HTML code to be displayed on the client’s browser and the application server is responsible for managing session state, enforcing business rules and processing logic (Chen and Heath, 2005). The database server is the component that provides access to and storage of data pertaining to the application and often times has database
