object focused hypermedia design and style model
Excerpt from Term Paper:
Object Focused Hypermedia style model and the four-step procedure involved in the progress the style. This section provides an explanation for each and every step in the procedure. Then we all will discuss the past, present and foreseeable future business uses of the model. This will check out the importance of the model in corporate applications that are conducted throughout the Internet. All of us will also give details about the compatibility with the model and compare the model to similar applications such as HDM and OOHM. Finally, all of us will discuss the strengths and weaknesses of the model. Which include that navigational design of the model as well as the costly cost to do business and training involved in implementing the application.
There will be several types of sources used throughout this discussion. Most of these sources will be works and articles written by Rossi and Schwabe who created the Object Oriented Hypermedia Style Method. Additionally there will be an array of article authored by computer programming experts and analysts.
Brief overview of the Object Focused Hypermedia Style Model
The item Oriented Hypermedia Design Style uses “abstraction and composition devices within an object oriented framework to permit a succinct description of complex details items, and on the other hand, allow the standards of sophisticated navigation habits and software transformations. inches (Rossi and Schwabe 1998) OOHDM is usually developed through a four stage process including; conceptual design, navigational design and style, abstract interference design and implementation. (Rossi et approach. )
Conceptual Design Period
During the conceptual design phase the type of the application site is created employing object oriented modeling guidelines. The creation of the software domain establishes the discourse of the app. There are two sorts of objects that are represented in this stage: the things that provide computational support and the objects that will be perceived as nodes in the navigational design stage. (Rossi ainsi que al. )
The navigational design period is very important to the success of any hypermedia application since navigation is what separates hypermedia design from the other applications. Course-plotting allows users to get around a space created of objects. During this stage transformations will be specified which usually determine how course-plotting will work
The third period is the abstract interface design phase identifies interface objects that are in charge of mediating user interaction with navigation things. The interface model identifies which software objects the consumer will perceive; which program objects will activate routing; how media interface things will be coordinated; and the program transformations which will take place. (Rossi et al. )
Throughout the final stage of execution the umschlüsselung is created for the things in the conceptual, navigational and abstract software phases. All of the proceeding phases are done individually of the setup platform. (Rossi et approach. )
Earlier Present and Future Organization Uses
Previous Uses
Theodor Holm Nelson created the Hypermedia Design Model in the mid-60’s. He wished to create a system by which the reading of different documents was not subject to series. (Hypermedia 2001, 1) Before the Hypermedia model was used to simply make web-based applications. The primary use of Hypermedia was going to reduce document transfer occasions and put together information in a format that might be accessible in people over the World Vast Web. Hypermedia also helped to create systems and early on navigation systems for businesses.
The OOHDM model was created to simplify the hypermedia model and to addresses some of the complications presented by the model. OOHDM did this by creating a navigational system and navigational patterns that allow businesses to provide buyers with useful content over the Internet.
Present Uses
The current uses of OOHDM involve creating e-commerce alternatives. E-commerce is definitely fast becoming well-liked as a way of delivering of business techniques and applications over the Internet. An increasing number of organizations require the functionality of web-based solutions with functionality to complete commercial transactions over the World Vast Web. These kinds of transactions are the acceptance of credit cards in order that customers could make purchases on the net and the capacity to provide buyers will useful content advice about the business. (Abrahao, Fons, Pastor 2000, 2)
A practical application is important because businesses understand that what sort of website features will possibly create replicate customers or perhaps discourage consumers from browsing site. It is crucial that a internet site is easy to navigate and that it capabilities in an successful manner. Also, it is important for a small business to be able to right problems with the system quickly, that can prevent the loss of customers and profits. Due to the demands which can be placed on organization to have an useful website an accurate software development process is required. (Abrahao, Fons, Pastor 2150, 2) The OOHDM procedure provides the stability needed to support an e-commerce site.
OOHDM is also utilized to improve the capabilities of Net information systems through the use of style patterns, which make websites easier to navigate. OOHDM is used in this field because it provides for a clear splitting up of conceptual, navigational and interface patterns. These differences are crucial because it permits programmers to pay attention to the hypermedia metaphor of Web Details Systems. (Rossi, Schwabe, Lyardet 1999, 3)
Future Uses
OOHDM will still be used to help business with e-commerce alternatives and building Web Info Systems. It truly is evident which the method will certainly continue to expand and more analysis will be done to make the approach even more successful. This effectiveness would make the program less expensive to keep up and help to make Web Pages even easier to find their way. In addition people inevitably always be new applications that are discovered and applied instead of OOHDM.
Compatibility
Wearer’s hardware requirements for text- and graphics-based hypermedia is very modest, and the most new PCs and Mac pcs have sufficient speed to play video clips. Conversely there is a problem that is created when the unit is used on a network. It is because the application is incredibly complex and wishes large amounts of bandwidth to control properly. The fact that the system of band width solutions can be improving on a consistent basis does simply no negate the very fact that program can outstrip the network bandwidth. (Tissue, 4)
Authorities believe that bandwidth constraints will most likely continue for many years. In addition the limitations are used to place sensible constraints on the characteristics of the materials that can be efficiently dispersed over the World Wide Internet. It is important to keep in mind that bandwidth considerations include the end users network links, which may develop a variety of file-transfer speeds. (Tissue, 4) The OOHDM program itself could be implemented of all hypermedia-supported platform. (Ashman, The star, Kukkonen 99, 7)
Side by side comparisons
The following a comparison of OOHDM to approaches such as HDM, ADM, OOHM, OOWS and OOH is based on conceptual design and navigational design and style and interface design. The goal of this assessment is to plainly explain right after that the Thing Oriented Design Method offers with these other applications. This kind of comparison is taken from this article “Building Web commerce Applications via Object-Oriented Conceptual Models”
Throughout the conceptual style phase, the Hypermedia Design Model approach is based on E-R diagrams and utilize the Target Oriented model. The Araneus Design Unit (ADM) is usually not based upon a conceptual model and depends on the navigational model. The thing Oriented Hypermedia Design Style uses an Object Oriented conceptual model based upon modifications in the Unified Modeling Language these modifications tend not to permit the items of the program to offer solutions to the user. The OOWS and OOH-Method use the Object Oriented Method as a conceptual model. (Abrahao, Fons, Prelado 2000, )
In the navigational design phase, all of these applications introduce client and hyperlink concepts as the fundamental structures for the reason of hypermedia systems. On the other hand, the explanation is regarded as by the methods in different techniques. These ways to the answers can be segregated into two categories. The Hypermedia Design and style Model and the Araneus Style model signify the first category. The 2nd category involves the OOWS, OOHDM and OOH-Methods. (Abrahao et al. )
The first category does not make any variation between the conceptual and navigational models, but instead that they represent navigational characteristics in a conceptual version based on E-R design. On the other hand the second category distinguishes between an Object Focused conceptual version and a navigational style, which manages the observation of each end user of the data system. (Abrahao et al. )
Within the second group, there is also a big difference in the navigational unit in OOWS and OOHDM (navigational context and node, respectively), which is a feature, made up of many groups from your conceptual style. While, in OOH-Method, the navigational product is a school from the conceptual model (navigational class). In addition , a foundation (navigational target) is used to group classes. This building block does not mean that there always be any necessary navigation; it can be simply employed for the organizational purposes in the method. This notion is also defined in Object Focused Hypermedia Design Model app as navigational context. (Abrahao et approach. )
The final aspect of navigational design consists of the powerful behavior in the various designs. Neither
