Information System Coursework

Differences between the Vertical and Horizontal Portals  

[blur] Vertical portals play the role of entry points, which facilitates specific markets, niches of the specific industries, interests or the subject areas. The horizontal portal refers to websites that play the role of an entry point to various firms, which are in the same industry. [/blur]

[blur] The major differences between the two can be traced to the fact that while vertical portals may meet the security level needs, they cannot be in the market without the proper definition of what is regarded as secure. Horizontal portals may tend to be a bit vulnerable since some section of the site may not be functioning yet they may still be incorporated to the system of the site. Another difference arises from the fact that the vertical portals do not facilitate the users to customize pages as in the case of the horizontal portals. [/blur]

Two Problems with RFID technology

[blur] RFID technology faces various challenges. The two most notable ones are the standards of implementations and the ease of being disrupted. Under the standards, most of the manufacturers in the market have been opting for different techniques towards the development of the devices. These different standards affect the ability of these gargets to be used in multiple environments. Talks to developing universal standards that define how the devices are developed have not made much success. The ease of disruption arises from the fact that these systems employ the use of electromagnetic spectrums, which are easy to jam. [/blur]

ASP problems

[blur] Configuration is the most notable issue, which is visible through the OOM, High Memory, Hangs, Deadlocks, and Performance. The second challenge is the external root cause, which arises from deployment of other support software such as antivirus. Such software’s affect the concurrency and in some instances, they may affect the performance of the site since the development of different software relies on different techniques. [/blur]

SaaP problems

[blur] SaaP adoption just like any other form of services has challenges with the level of access that is granted to the third parties. Such third parties may have access to one’s profile especially considering the type of the software that has been deployed. The second challenge of using SaaP arises from the lack of proper mechanisms of determining which software should be deployed. Onc the agreement is done, the service provider reserves the right to the software that is being used. [/blur]

Joint Application Design

  [blur] JAD focuses on the process of developing an application, which focuses on involving the user. JAD considers the user to know some of the aspects that should be in the system and thus involves them in the development process. [/blur]

Forward And Reverse Auction Give an Example of Each

    [blur] Forward auction focuses on a single seller offering an item for sale while the buyers compete by placing bids and increasing quotes of price. The forwards auctions are better known since they are the conventional forms of selling [/blur]

[blur] Reverse auction – in this type of auction, buyers tend to negotiate once they are made aware of the seller’s intent to sell. In essence, this pushes down the price. In the course of negotiation, the buyers will make their proposals and in the process, the one with the lowest bid wins. Procurement in most companies adopts this structure of selling. [/blur]


           [blur]   It is the process of removing or cutting the intermediaries rather than relying on the traditional notion of distribution channels. Disintermediation would not be successful if a company has not managed to establish the link such as the setting up of web portals or creating applications, which facilitate interaction with its customers, especially those customers that in different parts of the world.
