In week 5 I had the chance to know more about Decision Support System:

DECISION SUPPORT SYSTEM (DSS)

*       An organized collection of people, procedures, software, databases and devices used to support problem-specific decision making.

*       DSS are used to support unstructured or semi-structured problems that   require human judgment.

*       Offer the potential to generate higher profits, lower costs and better products and services.

*       DSS Often based on spreadsheet software.

TRANSACTION PROCESSING SYSTEM (TPS)

*         Information system that captures and processes data generated perform the activities associated with transaction processing, which include the following:

ü  Recording a business activity such as a student’s registration, a customer’s order, an employee’s timecard or a client’s payment.

ü  Confirming an action or triggering a response, such as printing a student’s schedule, sending a thank-you note to a customer, generating an employee’s paycheck or issuing a receipt to a client.

ü  Maintaining data, which involves adding new data, changing existing data, or removing unwanted data.

As we know that “The transaction processing system records the data from everyday operations throughout every division or department in the organization. Each division or department is tied together through the TPS to provide useful information to management levels throughout the company”.
