A Business Analysis of the Boject Oriented Hypermedia Design Model

Extracts from this document...

Introduction

A Business Analysis of the Object Oriented Hypermedia Design Model This discourse will provide a brief overview of the Object Oriented Hypermedia design model and the four-step process involved in the development of the model. This section will provide an explanation for each step in the process. Then we will discuss the past, present and future business uses of the model. This will explore the importance of the model in business applications that are conducted through the Internet. We will also provide details about the compatibility of the model and compare the model to similar applications such as HDM and OOHM. Finally, we will discuss the strengths and weaknesses of the model. Including that navigational design of the model and the costly overhead and training involved in implementing the application. There will be several types of sources used during the course of this discussion. Most of these sources will be essays and articles written by Rossi and Schwabe who invented the Object Oriented Hypermedia Design Method. In addition there will be a myriad of article written by computer programming specialists and researchers. Brief overview of the Object Oriented Hypermedia Design Model The Object Oriented Hypermedia Design Model uses "abstraction and composition devices in an object oriented framework to allow a concise description of complex information items, and on the other hand, allow the specification of complex navigation patterns and interface transformations." (Rossi and Schwabe 1998) OOHDM is developed through a four step process which includes; conceptual design, navigational design, abstract interference design and implementation. ...read more.

This comparison is taken from the article, "Building E-Commerce Applications from Object-Oriented Conceptual Models" During the conceptual design phase, the Hypermedia Design Model approach is based on E-R diagrams and does not utilize the Object Oriented model. The Araneus Design Model (ADM) is not based on a conceptual model and depends on the navigational model. The Object Oriented Hypermedia Design Model uses an Object Oriented conceptual model based on modifications of the Unified Modeling Language these modifications do not permit the objects of the application to offer services to the end user. The OOWS and OOH-Method use the Object Oriented Method as a conceptual model. (Abrah, Fons, Pastor 2000) In the navigational design phase, all of these applications introduce node and link concepts as the fundamental structures for the explanation of hypermedia systems. Conversely, the explanation is considered by the approaches in different ways. These approaches to the explanations can be separated into two categories. The Hypermedia Design Model and the Araneus Design model represent the first category. The second category includes the OOWS, OOHDM and OOH-Methods. (Abrah, et al) The first category does not make any distinction between the conceptual and navigational models, but instead they represent navigational characteristics in a conceptual model based on E-R design. On the other hand the second category distinguishes between an Object Oriented conceptual model and a navigational model, which regulates the observation of each user of the information system. (Abrah, et al) Within the second group, there is also a difference in the navigational unit in OOWS and OOHDM (navigational context and node, respectively), which is an element, made up of several groups from the conceptual model. ...read more.

Conclusion

We discovered that the model is rather complex in design and execution. Then we discussed the past, present and future business uses of the model. Our investigation found that in the past hypermedia had been used to simply compile information and make it accessible and that the early hypermedia system provided for navigation and networking for businesses. The present business uses of the model are e-commerce and Web Information Systems. Our research found that these business uses are essential if businesses desire to survive as part of the new economy. We concluded that in the future the model will still be used in e-commerce and web based solution we also believe that the application will be better researched and create even better navigation of Web sites. We also explored the compatibility of the model and discovered that the model could be implemented onto most hypermedia platform. In addition we compared the model to similar applications such as HDM, ADM and OOHM. Finally we will discuss the strengths and weaknesses of the model. We found that the application provides for superior navigation and resolves some of the problems presented by the HDM. The weaknesses of the model included the complexity of the application and the expense of implementing and maintaining the technology. As we have discovers the Object Oriented Hypermedia Design Model is essential to the success of the Internet specifically in business uses and navigation of Web sites. It is my sincere desire that this paper has aided you in understanding the complex world of the Object Oriented Hypermedia Design Model. ...read more.
