If they want to print out the result slip, they may complete the action by pushing the print button from the system. Otherwise, the student can logged out from the system if they don’t want to print out the result slip.

3. Develop an activity diagram with swim lane to illustrate the sign up course use case.

Kudler Fine Foods Network Topology Paper

...three of their existing sites together using wireless and VOIP technology. Distributed Computing Currently all three of the Kudlers facilities utilizes a distributed computing system using the same configuration of single server and multiple pc’s, each with a single UPS and 56k modem for connectivity. The computers are connected to an Ethernet backbone (typically a hub that is not very efficient in handling network traffic for many computers) and the 56k modem is the only external connectivity that the sites have. Centralized Computing In order to bring this system up to standards they will need to update to a more centralized computing system which all computing is done on a centrally managed computer system and the users use a dumb terminal (thin client) to connect to these central computers. The cost associated with this has been reduced over the years and was only used previously in enterprise environments but now more businesses are moving over to this type of system. Network Topologies Kudlers three offices use almost identical setups for their servers, POS systems and their site connectivity. They all use the same bus (Hub) connection for onsite connectivity using outdated equipment that has several drawbacks. This type of network is very hard to troubleshoot and if one system goes down it could cause other issues.

This allows the computers to communicate to each other and also share resources. While allowing the user to use the computer as he or she would use a single integrated computing facility. Examples of failures in a distributed system include, stop failure, Halt failure, Network Failure, and Distributed File System Namespace access failures. Distributed File System Namespace access failures in Windows On Windows Vista and later one of the following error messages may occur: Windows cannot access \\\ The connection may fail due to any of the following reasons: Failure to connect to a domain controller to obtain a DFSN namespace referral, Failure to connect to a DFSN server, Failure of the DFSN server to provide a folder referral.

All the doctors want to be able to see their patients and access patient information at any of the offices. The time of operation of all offices will be from 7 a.m. to 9 p.m., based on the schedule of the doctors. Since 1986, the offices located in the north and the south have been using an IBM PC/XT and a dot matrix printer with custom software to manage the patient information. These computer systems need to be upgraded, and the data needs to be typed manually into the new computer system. The office located in the city center is more modern; however, the software and hardware it uses may need to be upgraded to store the new information and meet the needs of additional network connectivity. This office will be the central office, and it will have the maximum activity. This office has a Fedora Core Linux Operating System version 8 on a Dell server and uses TCP/IP to communicate with the existing workstations that have XP sp2. This office has the Medical Manager software operating on the server. This office also has two workstations in the reception area, one workstation in the nurse’s office and one in the supervisor’s office that is shared by the office supervisor and the billing manager.

Zara Case

...ZARA: IT for Fast Fashion With ZARA's fashion business expanding, Salgado and Sanchez have a critical decision to make on whether to upgrade the current, seemingly out of date IT system. Like other large clothing retailers, ZARA adopts a highly standardized business model for ordering, design, manufacturing and procurement across all product categories and regions. However, unlike most clothing retailers, ZARA's business model is based on fast delivery times with minimal inventory, decentralized decision making process and very low data integration among different stores. Unlike its competitors, Zara relies on its individual store managers and designers, rather than an elite team of senior managers, to perform market research on latest trends and decide what clothes to design and procure. ZARA's approach to Information Technology is based on its business needs. In order to establish itself as a brand, which aligns closely with customers' taste, ZARA needs to have information on latest trends from all its stores to keep pace with the ever-changing fashion world. On the other hand, ZARA's popularity and high growth requires an upgraded IT system, which can be easily replicated and scalable to new stores. ZARA's current DOS system serves this purpose efficiently as it is easy to install in a newly opened store and requires little training. ZARA's approach of simple, non-integrated low cost IT investment is well in sync with its decentralized...
