Answer 1

The example i would like to provide is an organization which handles thousands of students every year and has thousands of employees working in it.

Lovely Professional University, India - This is a university which has implemented their own University Management System which has an abstracted and limited access to each and every member of the University. The IT system is known as the UMS and everyone is provided with IDs and Passwords. The system holds each and every activity inside the university and records all the academic and administrative data in it.

Transaction Processing System - It deals with the different transactions made in the system. Real examples are described in the below bullet points format:

a. Transactions of Online Assignments among tyeachers and students.

b. Transactions of College notifications on the System.

c. Transactions of Attendance of students.

d. Transactions of Results

e. Fees transaction

f. Transactions of Complaints.

TPS deals with the transactions made at the organization's operational level. The output for TPS is the Details of the submitted assignments, marks obtained in the course, percentage of attendance in a particular course, Amount of fees submitted, Details of complaints etc.

Management Information system - This system provides reports to the management level of the organization. It provides an access to company data.

As per the University Management system which is an interrelationship of TPS and MIS in itself, the administrative data is the one included in this system. This data helps the middle level managers in planning, organizaing, decision making and controlling different resources in the organization.

The TPS provides the summary of all the available resources in the University to MIS in the form of a report. MIS allows the report to be helpful to the middle level managers to identify and analyze. Example - The attendance reports as submitted through TPS is used to generate the registration reports on which students are allowed to sit for final examinations. Fees transactions are used to identify defaulters and notify them .

Decision Support System - It includes a knowledge base using which decisions are taken using the UMS by using the data available in the UMS.

Example - Students having attendance less than 70% are automatically detained from the examinations for that semester. The knowledge base of the decision support system aumatically identifies the attendance defaulters and disallows them to write exams.

Executive support system -

It take the external and internal aggregate data as the input and processes them to generate the information from that given data so that strategies can be formed through it.

Example - Admissions are the most real examples for the same. Every year, University spends different amounts for different states where they set up the help desk for new admissions. Using the data of the last year, ESS determines the required information formt he system and helps in identifying the strategy of spending the budget for marketing in different states and nearby countries. ESS is further used for admission forecasting every year.
