1)a. The system did not provide a graphical interface and did not provide for ad-hoc reporting. Students use a tool such as System Architect (Popkin Software) for creating the models.
b. The old system did not provide the ability to monitor student progress. The new system will need to capture this data of students register for designated classes in a batch process using the class rosters provided by the Colleague system. At the end of each semester, a batch of grade rosters will be used to enter the grades into the system too.
c. The old system was not even based on a file server architecture since the client PCs in the program were not part of a single LAN. Active Server Pages has built in objects for connecting to the database and for handling communication with the browser.
d. The old system did not support remote access. A web-enabled system would meet the need for remote access to a common database.
e. The old system did not meet the needs of the program like remotely access a single database, create a semester course schedule and to view student transcripts, reporting on student progress on completing prerequisites, exception reporting on students failing to meet program standards. The process is modeled using Data Flow Diagrams (DFDs). The top level DFD is the Context Diagram, shown as Figure 1, and it lays out the net inputs and outputs to the E-Administrator system. The system consists of 5 functions – Admissions, Registration, Scheduling, Reporting and Data Maintenance. The next level DFD is the System DFD, and it lays out the events associated with the functions.
In a conclusion, they developed a logical process model of the MSMIS system, a logical data model of the MSMIS system, a Network Architecture DFD, a Physical Schema, a prototype of the Reports, a prototype of the Input Forms, a prototype of the User Interface and describe some of the tools used in the construction of a system to solve problems.
2)Yes, it is.
Given the absence of a common LAN and the lack of network support staff, the typical File server and Client/Server distributed architectures were not feasible.
However, every client was now connected to the Internet. There is no need for any special network support. In terms of hardware, the clients already existed in the form of the PCs on each desk. A server with its own IP address would be needed. In terms of software, the system would need a web server, a database management system, an integrated development environment (IDE) for program construction, and browsers on the clients.
3)a)Haier uses B2B and B2C e-Commerce.
In the website (CNNIC), Haier website ranked first in Chinese industrial website. With high technology, high quality products, Haier website has always paid attention to scientific research and development.
Haier is always active to know customer needs, judging if products are competitive based on the questionnaire survey.
b) Haier uses software-as-a-service, push, F2b2c, VoIP and Web 2.0 internet business models. In terms of software-as-a-service, customers can buy products on line. I terms of push, people can get information, services and product offerings on Haier’s network. Customers can find out on the internet that Haier also provides product specification. On the network of Haier, it offers services like send voice communications and online collaboration.
c)Haier adopts Online ads marketing mix.
d)Haier uses Digital Wallet and Smart Cards payments systems.
