Is there a relationship between MIS and DSS?

Answer 1

TPS is an acronym describing Transaction Processing Systems. TPS

systems are exactly what the name implies - a system that processes

transactions that occur within an organization or business. TPS

systems tend to perform routine operations and serve as a foundation

for other systems. Transactions are business operations such as

customer orders, purchase orders, receipts, time cards, invoices,

payroll checks and, yes, college registrations.

A Transaction Processing System can consist of :-

- Data Collection eg getting registration papers.

- Data Editing eg making the paper ready for input to the system.

- Data Correction eg sorting out incorrect dates of birth, postal

codes etc.

- Data Manipulation eg assigning students to courses, car parking,

halls of residence etc .

- Data Storage eg where the data is physically located on disks/tapes

etc.

- Document Production eg hard copy of registration forms, ID cards

etc.

Here are some examples of TPS systems

- Sales/marketing systems for market research, pricing, promotion, new

product introduction.

- Manufacturing/production systems for scheduling, purchasing,

shipping/receiving, engineering, operations.

- Human resources systems for personnel records, benefits,

compensation, labor relations, training.

- Industry specialized systems such as university registration,

freight shipping and rates, property management and renting etc.

So you can see that a TPS covers a wide variety of both manual and

automated tasks, in support of an overall process or business.

MIS is an acronym for Management Information System, which is a system

that provides periodic and predetermined reports that summarize

information.

It is usually attached, and part of, a bigger Transaction Processing

system, and exists to give Management reports of activity eg an MIS

attached to a larger Student Registration system might give reports on

numbers of students registering, amounts of course fees defaulted etc

etc, -- information that the college would require to make management

decisions.

So MIS supports the management level by providing routine summary

reports and exception reports (e.g. Which students were here in the

Fall who did not choose to return in the Spring?) and MIS differs from

TPS in that MIS deals with summarized and compressed data from the

TPS.

(You might come across the term DSS. This stands for Decision Support

Systems Typically, they provide the ability to do "what if" analysis.

DSS uses the data from MIS, but is more a "right now" analysis than

the long-term structured analysis of MIS.)
