Management Information Systems Chapter 3

Business Intelligence (BI)

Collective, information about your customers, your competitors, your business partners, your competitive environment, and your own internal operations

Online Transaction Processing (OLTP)

The gathering of input information, processing that information, and updating existing information to reflect the gathered and processed information

Operational Databases

A database that supports OLTP

Online Analytical Processing (OLAP)

The manipulation of information to support decision making

Database

A collection of information that you organize and access according to the logical structure of that information

Relational Database

Uses a series of logically related two-dimensional tables or files to store information in the form of a database

Relation

Describes each two-dimensional table or file in the relational model

Data Dictionary

Contains the logical structure for the information in a database

Primary Key

A field that uniquely describes each record

Foreign Key

A primary key of one file that appears as another file

Integrity Constraints

Rules that help ensure the quality of the information

Database Management System (DBMS)

Helps you specify the logical organization for a database and access and use the information within a database

DBMS Engine

Accepts logical requests from the various other DBMS subsystems, converts them into their physical equivalent, and actually accesses the database and data dictionary as they exist on a storage device

Physical View

Deals with how information is physically arranged, stored, and accessed on some type of storage device such as a hard disk

Logical View

Focuses on how you as a knowledge worker need to arrange and access information to meet your particular business needs

Data Definition Subsystem

Helps you create and maintain the data dictionary and define the structure of the files in a database

Data Manipulation Subsystem

Helps you add, change, and delete information in a database and query it for valuable information

View

Allows you to see the contents of a database file, make whatever changes you want, perform simple sorting, and query to find the location of specific information

Report Generators

Helps you quickly define formats of reports and what information you want to see in a report

Query-By-Example Tools (QBE)

Help you graphically design the answer to a question

Structured Query Language (SQL)

A standardized fourth-generation query language found in most DBMSs

Application Generation Subsystem

Contains facilities to help you develop transaction-intensive applications

Data Administration Subsystem

Helps you manage the overall database environment by providing facilities for backup and recovery, security management, query optimization, concurrency control, and change management

Backup

A copy of the information stored on a computer

Recovery

The process of reinstalling the backup information in the event the information was lost

Data Warehouse

A logical collection of information - gathered from many different operational databases - used to create business intelligence that supports business analysis activities and decision-making tasks

Data-Mining Tools

The software tools you use to query information in a data warehouse

Query-and-Reporting Tools

Similar to QBE tools, SQL, and report generators in the typical database environment

Multidimensional Analysis Tools (MDA)

Slice-and-dice techniques that allow you to view multidimensional information from different perspectives

Data Mart

A subset of a data warehouse in which only a focused portion of the data warehouse is kept

Competitive Intelligence (CI)

Business intelligence focused on the external competitive environment

Digital Dashboard

Displays key information gathered from several sources on a computer screen in a format tailored to the needs and wants of an individual knowledge worker

Data Administration

The function in an organization that plans for, oversees the development of, and monitors the information resource

Database Administration

The function in an organization that is responsible for the more technical and operational aspects of managing the information contained in organizational information repositories
