Chapter 7 8

An MIS produces routine, ad-hoc (ondemand) and exception report:

Ad-hoc ( on- demand) reports: Nonroutine reports.

Drill- down report: Reports that show a greater level of detail than is included in routine reports.

Key- indicator reports . Reports that summarize the performance of critical activities .

Comparative reports . Reports that compare performance of different business units or time periods.

Exception report . Report that include only information that exceeds certain threshold standard

Chapter 7 9

Information systems can also be function-specific

Typical function- specific system are accounting, finance, marketing, operations

(POM), and human resources management

7.2 Transaction Processing

Information Systems (TPS)

Information system that supports routine, core business transactions.

“ Copyright 2005 John Wiley & Sons Inc.”`

Chapter 7 12

Objectives of a TPS

To provide all the information needed by law, by management and / or by organizational policies to keep the business running properly and efficiently to efficiently handle high volume of data, to avoid errors due to concurrent operations to handle large variations in volume

To avoid downtime, never lose results, and maintain privacy and security

To interface with many IT applications, including epayment, e-procurement and e-marketing.

Chapter 7 13

Activities and Methods of TPSs

First, data are collected by people or sensors and entered into the computer via any input device. Next the system processes data in one of two basic ways: batch or online processing.

 Batch processing: processes data in batches at fixed periodic intervals.

 Online processing: processes data as soon as a transaction occurs.

Chapter 7 14

The Major Characteristics of a TPS

 Typically . Large amounts of data are processed.

 The source of data are mostly internal , and the outputs is intended mainly for an internal audience . This characteristic is changing somewhat, since trading partners may contribute data and may be permitted to use

TPS output directly .

The TPS processes information on a regular basis: daily, weekly, biweekly and so on.

 Large storage (database) capacitv is required.

 High processing speed is needed due to the high volume.

 The TPS monitors and collects past data

Input and output data are structured. Since the processed data are fairly stable, they are formatted in a standard fashion.

 A high level of detail (raw data, not summarized) is usually observable, especially in input data but often in output as well.

 Low computation complexity (simple mathematical and statistical operations) is usuallv evident in a TPS.

 A high level of accuracy, data integrity, and security is needed. Sensitive issues such as privacy of personal data are strongly related to TPSs.

 High reliability is required. The TPS can be viewed as the lifeblood of the organization . Interruption in the flow of TPS data can be fatal to the organization .

 Inquiry processing is a must . The TPS enables users to query files and databases ( even online and in real time)
