(Book ID: B1136)
Assignment - Set- 1 (60 Marks)
Marks-60

Attempt each question. Each question carries 10 marks:
1. What is MIS? Define the characteristics of MIS? What are the basic Functions of MIS? Give some Disadvantage of MIS?
The industrial revolution has slowly replaced man power with machines. There emerged the use of computer for data processing. The digital computer was mainly designed to handle scientific calculations. During 1940 to 1960 computers were used commercially for census and payroll work which involved large amount of data processing. Since then the commercial application exceeded the scientific applications.
Computer Based Information systems are of vital importance in modern organization. Systems professionals analyze, design, develop, implement and manage state-of-the-art telecommunications, multi-media and other computer-based information systems. In addition to maintaining traditional transaction processing systems, today’s IS professionals are involved in exciting developments in computing systems, such as decision support and expert systems, database development and enhancement, development and use of Graphical User Interfaces (GUI), systems design using object oriented programming, design and management of telecommunications systems, and the management of end-user computing. So you can define MIS is a method of generating information which is used by management or organization for decision making, control of activities and operations etc

 MIS characteristics
· It supports transaction handling and record keeping.
· It is also called as integrated database Management System which supports in major functional areas.
· It provides operational, tactical, and strategic level managers with east access to timely but, for the most, structured information.
· It supports decision –making function which is a vital role of MIS.
· It is flexible which is needed to adapt to the changing needs of the organization.
· It promotes security system by providing only access to authorized users.
· MIS not only provides statistical and data analysis but also works on the basis on MBO (management by objectives). MIS is successfully used for measuring performance and making necessary change in the organizational plans and procedures. It helps to build relevant and measurable objectives, monitor results, and send alerts.
· Coordination: MIS provides integrated information so that all the departments are aware of the problem and requirements of the other departments. This helps in equal interaction of the different centers and connects decision centers of the organization.
· Duplication of data is reduced since data is stored in the central part and same data can be used by all the related departments.
· MIS eliminates redundant data.
· It helps in maintaining consistency of data. It is divided into subsystems. Handlings with small systems are much easier than an entire system. This helps in giving easy access of data, accuracy and better information production.
· MIS assembles, process, stores, Retrieves, evaluates and disseminates the information.
Function of MIS
The main functions of MIS are:
· Data Processing: Gathering, storage, transmission, processing and getting output of the data. Making the data into information is a major task.
· Prediction: Prediction is based on the historical data by applying the prior knowledge methodology by using modern mathematics, statistics or simulation. Prior knowledge varies on the application and with different departments.
· Planning: Planning reports are produced based on the enterprise restriction on the companies and helps in planning each functional department to work reasonably.
· Control: MIS helps in monitoring the operations and inspects the plans. It consists of differences between operation and plan with respect to data belonging to different functional department. It controls the timely action of the plans and analyzes the reasons for the differences between the operations and plan. Thereby helps managers to accomplish their decision making task successfully.
· Assistance: It stores the related problems and frequently used information to apply them for relative economic benefits. Through this it can derive instant answers of the related problem.
· Database: This is the most important function of MIS. All the information is needs a storage space which can be accessed without causing any anomalies in the data. Integrated Database avoids the duplication of data and thereby reduces redundancy and hence consistency will be increased.
· The major function of MIS lies in application of the above functions to support the managers and the executives in the organization in decision-making.
Disadvantages of MIS
The following are some of the disadvantages of MIS:
· MIS is highly sensitive: MIS is very helpful in maintaining logging information of an authorized user. This needs to monitor constantly.
· Quality of outputs is governed by quality of inputs.
· MIS budgeting: There is difficulty in maintaining indirect cost and overheads. Capturing the actual cost needs to have an accrual system having true costs of outputs which is extremely difficult. It has been difficult to establish definite findings.
· MIS is not flexible to update itself for the changes.
· The changes in the decision of top level management decrease its effectiveness.
· Information accountability is based on the qualitative factors and the factors like morality, confidence or attitude will not have any base.


2. Explain Knowledge based system? Explain DSS and OLAP with example?
Knowledge Based System (KBS)

3. What are Value Chain Analysis & describe its significance in MIS? Explain what is meant by BPR? What is its significance? How Data warehousing & Data Mining is useful in terms of MIS?

4. Explain DFD & Data Dictionary? Explain in detail how the information requirement is determined for an organization?

5. What is ERP? Explain its existence before and its future after? What are the advantages & Disadvantages of ERP? What is Artificial Intelligence? How is it different from Neural Networks?

6. Distinguish between closed decision making system & open decision making system? What is ‘What – if‘ analysis? Why is more time spend in problem analysis & problem definition as compared to the time spends on decision analysis?

Attempt each question. Each question carries 10 marks:
1. How hardware & software support in various MIS activities of the organization?
Explain the transaction stages from manual system to automated systems?

Hardware support for MIS
Generally hardware in the form of personal computers and peripherals like printers, fax machines, copier, scanners etc are used in organization to support various MIS activities of the organization.
1.6.1 Advantages of a PC: you can find the following advantages a personal computer offers:
a) Speed – A PC can process data at a very high speed. It can process millions of instructions within fraction of seconds.
b) Storage – A PC can store large quantity of data in a small space. It eliminates the need of storing the conventional office flat files and box files which requires lots of space. The storage system in a PC is such that the information can be transferred from one place to another place in electronic form.
c) Communication – A PC on the network can offer great support as a communicator in communicating information in the form of text and images. Today a PC with internet is used as a powerful tool of communication for every business activity.
d) Accuracy – A PC is highly reliable in the sense that it could be used to perform calculations continuously for hours with a great degree of accuracy. It is possible to obtain mathematical results correct up to a great degree of accuracy.
e) Conferencing – A PC with internet offers facility of video conferencing worldwide. Business people across the globe travel a lot to meet their business partner, colleagues, and customers etc to discuss about business activities. By video conferencing inconvenience of traveling can be avoided.

Input unit is used to give input to the processor. Examples of input unit –Keyboard, scanner, mouse, bar code reader etc.
A processor refers to unit which processes the input received the way it has been instructed. In a computer the processor is the CPU – Central Processing Unit. It does all mathematical calculations, logical tasks, storing details in the memory etc.
Output unit is used to give output s from the computer.
Examples of output unit – Monitor, printer, speakers etc.
