Morley and Parker (2010) define information system as a discipline that is formed from elements of business and computer science and is developing to form a separate area of scientific study.
It has been stated that “healthcare information systems and healthcare processes are closely entwined with one another. Health care processes require the use of data and information and they also produce or create information” (Wager et al, 2009, p.65)
Three basic components of system are explained by Bagad (2010) as input, process/transformation and output. In information system inputs are data that are going to be transformed. The process component of an information system transforms input into an output. Output is considered to be the final product of a system. In case of an information system, an output would be obtaining necessary information in a desired format (Currie, 2009).
Explanations of all of the components of information system are offered by Stair et al (2008) in the following manner:

Moreover, Hoyt et al (2008) and Carter (2010), discuss the role of intranet, i.e. a local communications network within organisation that is implemented on the basis of World Wide Web software in terms of effectively sharing information and knowledge within organisations. As Hoyt et al (2008) argue the advantages of intranet include information sharing in a fast manner, facilitating communication between members of the organisation in a cost-effective way.
