What is the major role of UTZ information systems?
What are the characteristics of the information UTZ receives that would make it valuable?
Analyze the industry that UTZ is in using the porter model, is it a good industry to be in?
What competitive advantage do you feel Utz has? How does information play into that competitive advantage

To make good and accurate decisions and work in the most productive and efficient way, knowledge workers today need (1) access to information and (2) tools to work with that
information.

Business Intelligence What is it?
Business intelligence is knowledge – knowledge about your customers, your competitors, your partners, your competitive environment, and your own internal operations
Where is BI found? Databases & Data warehouses

Key Terms Online transaction processing
(OLTP) – the gathering of input information, processing that
information, and updating existing information to reflect the gathered and processed information.
Operational database – database that supports OLTP.
Online analytical processing (OLAP) the manipulation of information to support
decision making.

Hierarchy of Data

THE RELATIONAL DATABASE MODEL Database
A collection of information that you organize and access according to the logical structure of that information.
Relational database model uses a series of logically related two-dimensional
tables (called relations) or files to store information in the form of a database.
Relation describes each two-dimensional table or file in the
relational model. The word relation here is in reference to the collection
of the data within one specific table.
![Page 10: Developing A Strategy For The Internet Age The Five Forces Model](https://reader036.vdocuments.us/reader036/viewer/2022062410/56815d34550346895dcb33aa/html5/thumbnails/10.jpg)
By carefully examining the definition given to “relational databases” we can clearly identify two parts to it:
1. Information – stored in a series of two dimensional tables, files, or relations.
2. Logical structure of the information.

Advantages of Database Approach Improved strategic use
of corporate data Reduced data
redundancy Improved data integrity Easier modification and
updating Data and program
independence Better access to data
and information
Standardization of data access
Framework for program development
Better overall protection of the data
Shared data and information resources

Disadvantages of Database Approach Relatively high cost of purchasing
and operating a DBMS in a mainframe operating environment
Increased cost of specialized staff Increased vulnerability

Data Warehouses and Data MiningData Marts – Smaller Data Warehouses
Data mart - a subset of a data warehouse in which only a focused portion of the data warehouse information is kept.
Data Marts Are Subsets of Data Marts Are Subsets of Data WarehouseData Warehouse

How Up-to-Date Should Data Warehouse Information Be?
To adjust class sizes in a university registration system
To alert people to changes in weather conditions To predict scores in professional football games
To adjust radio advertisements in light of demographic changes
To monitor the success of a new product line in the clothing retail industry
To adjust production levels of foods in a cafeteria To switch jobs to various printers in a network – by
the minute. To adjust CD rates in a bank To adjust forecasted demands of tires in an auto parts
store

MANAGING THE INFORMATION RESOURCE IN AN ORGANIZATION Who Should Oversee the
Organization’s Information? How Will Changes in Technology Affect
Organizing and Managing Information? Is Information Ownership a
Consideration? What Are the Ethics Involved in
Managing and Organizing Information?
