4. Transaction Processing System (TPS)
It supports day-to-day operations.
For example:
Order Entry Systems
Cheque Processing Systems
Account Receivable Systems
Accounts Payable Systems
Payroll Systems
Ticket Reservation Systems

5. Transaction Processing System (TPS)
Transaction processing is a set of procedures for handling the transactions.
Common activity includes:
Calculation
Classification
Sorting
Storage
Summarization

6. Examples: Sales Order Processing System:
The TPS data contains the list of products, available for sale, their prices and related data.
Railway Reservation System:
The TPS data contains the location of available seats.
It displays a message on the terminal indicating seats sold out to people.
It also prints the tickets and perhaps a mailing label for sending them.

7. Examples: So the TPS program generates two types of outputs:
It sends message back to the operator terminal
It generates printed documents

MIS: Measures and reports the performance of each of the
agents who will sell tickets.

agent’s sales and it regularly produce reports
about agent’s effectiveness.

16. Decision Support System (DSS)
An information system that utilizes decision models, a data base and a decision makers own insights in an ad-hoc, interactive analytical modeling process to reach a specific decision by a specific decision-maker. Or
DSS is a system for providing information to help management with new, un-structured decision making.

17. Example of DSS A strike by the dancer’s union--
It forces the cancellation of arranged dance performances.
The management of the dance association wants to know—
The impact on revenue of the cancellation of each performance.
A DSS could be used to process the ticket agencies data to produce the information.

20. MIS Vs. DSS Points MIS DSS Focus
On structured tasks and routine decisions
On semi structured tasks, requiring managerial judgment
Emphasis
On data storage
On efficiency
On data manipulation
On effectiveness
Reliance
On computer expert
On managers own judgment
Data Access
Indirect access by managers
Direct access by managers
