INFORMATION TECHNOLOGY AND CRM
data warehouse— a large reservoir of detailed and summary data that describes the firm and its activities, organized by the various business units in a way to facilitate easy retrieval of information describing the firm’s activities
data— facts and figures that are difficult to use because of their volume.
information— meaningful compilations and summaries of data that tell the user something that he or she did not already know
CRM architecture— facilitates the gathering of data, storing it, transforming it into information, and presenting the information to users.

A Basic CRM Model Data Sources
internal—business units, such as a manufacturing, finance , or sales
external—organizations and individuals outside the firm. Data Acquisition
computer-readable formats acquired from internal sources, data entry operators, or compatibility with touch points for external sources
Data Storage record file database data mart—a subset of the data warehouse that contains
data relating to a portion of the firm’s transactions.

A Basic CRM Model Data Management
database management system (DBMS)— software that maintains the data and makes it available for use
data dictionary—a detailed description of each data element

COMPUTER ARTHITECTURES
client/server— the stored data and functions that are performed on the data are allocated to the central server and to the user, called the client Exhibit 3.4: Tiered Client/Server Configurations Three commodities—(1) control over the user
interface, (2) the location of the software that performs the user’s functions, and (3) the location of the data—reside at the client level

DATA INPUT
Contact Points touch point—any transaction or customer interaction
with the organization Point of Sale Input
POS terminals—scan product data from bar codes and obtain customer data from credit cards, checks, or store identification cards
Keyed and Scanned Data Input keyed input—when POS terminals and EDI cannot be
used, the data most likely will have to be keyed into workstations by data entry operators
scanned input—when data can be optically scanned, i.e. credit card invoices and airline tickets
Internet Input Web-based systems—allow tracking of customer
information for search and purchasing behavior
11
DATA STORAGE
main memory secondary storage direct access storage storage area network (SAN)— allows
business units throughout the organization to store data on different servers.
storage resource management (SRM) software— allocates storage in the most efficient way by locating unused storage and allocating it where it can best be used
12
DATABASE STRUCTURES
database design— arrange the data so that it can easily be retrieved
hierarchical and network— the first structures, required that special physical links be built into the records to integrate data from multiple files
relational— structure that makes use of data elements already in the data tables to integrate the contents of multiple tables

analysis tools—include reports, database queries, and mathematical modeling, or on-line analytical processing (OLAP)
Reports and Database Queries repetitive report (or periodic report)—prepared
automatically according to a schedule, such as monthly, without requiring requests by users
special report—prepared when a special information need arises, such as a response to a database or data warehouse query

DATA ANALYSIS AND INFORMATION DELIVERY
Mathematical Modeling constructed in a software form and uses data and
users’ instructions to project what might happen in the future
On-line Analytical Processing (OLAP) an approach to quickly conduct analysis of data in
a data warehouse where the user is on-line with the system
22
DATA ANALYSIS AND INFORMATION DELIVERY
Data Mining how the user extracts previously unknown informatio
n from the large reservoir of the data warehouse, similar to the way that miners extract gold, coal, diamonds, and so on from the earth.
verification mode— to believe that the warehouse contains data in certain forms or patterns and conducts repetitive queries to support this hypothesis.
knowledge discovery— the user lets the system determine the path to follow in conducting the analysis

What is the difference between a data warehouse and a database?
A data warehouse is a large reservoir of detailed and summary data that describes the firm and its activities, organized by the various business units in a way to facilitate easy retrieval of information describing the firm’s activities. A database is an accumulation of computer-based data that is arranged in a format to facilitate retrieval. A data mart is a subset of the data warehouse that contains data relating to a portion of the firm’s transactions.
