9 management capabilities (Chen and Heath, 2005). When a client browser requests a page from the Web server the server retrieves the requested data, if any, from the database and then the server compiles the underlying programming language on that page which subsequently is delivered to the client browser in a readable form. Figure 1 - Web Application Components (Chen and Heath, 2005). Relational Database Technologies: An important part of developing a Web-based application is how to store the data that will be used or collected. There are numerous ways one can store the application data, however, Westman (2002) suggests the use of a good RDBMS. RDBMS software allows an organization to centralize and efficiently manage their data while also providing access to that data by other programs (Laudon & Laudon cited in Liao, 2005). According to Lemieux (1996) a database system should consist of the following components which need to interact together to ensure the meaning of the database system is preserved: • People. • A definition of data structures and their inherent constraints.
10 • The expression of the data structures as real objects. • The definition of a set of inference rules that may be used to derive facts from pure data. • The definition of explicit constraints. • The definition of a set of business functions. • Software components: database engine and operating system. • Appropriate hardware. The previous list is very general and does not specifically outline what a relational database should consist of, but rather shows the components that need to interact in a database system. In his book Database Systems, Beynon-Davies (2004) writes about the 12 rules set forth by Dr. E.F Codd, a researcher for IBM and considered by many to be the father of relational databases (Loshin, 2001), that describes a true relational database system. Using these rules Beynon-Davies (2004) scored Oracle’s RDBMS a 10 out of a possible 12. He states that the Oracle product uses tables as its primary data structure, it utilizes primary as well as foreign key constructs, uses null characters to represent missing or incomplete data, offers an on-line catalog and it uses SQL as its defined interface (Beynon-Davies, 2004). There are numerous database systems available that would provide a sufficient backend to a Web-based application. Microsoft Access, a DBMS originally designed for the desktop market and non-sophisticated users, could potentially be used for Web-based applications but is limited in the features it offers. Access lacks a fully-formed method of transaction management, is limited in terms of the volume of data it can manage satisfactorily, and lacks a system catalog which is essential for good database
