This document discusses data, text, and document management. It covers file management systems, database management systems, data warehouses, and enterprise content management. Effective data management is important for organizations to access and use data efficiently. It reduces data redundancy, inconsistency, and isolation issues. Database management systems help solve problems of file-based systems by providing centralized access to data. Data warehouses further organize vast amounts of data for analysis and decision making.

6. 3.1 Data, Text, and Document Management
Data, text, and documents are strategic assets. Vast
quantities are:
• created and collected
• then stored – often in 5 or more locations
Data, text, and document management helps
companies improve productivity by insuring that
people can find what they need without having to
conduct a long and difficult search.

7. Data Management
Why does data management matter?
• No enterprise can be effective without high quality data
that is accessible when needed.
• Data that’s incomplete or out of context cannot be trusted.
• Organizations with at least 1,000 knowledge workers lose
~ $5.7 million annually in time wasted by employees
reformatting data as they move among applications.
What is the goal of data management?
• To provide the infrastructure and tools to transform raw
data into usable information of the highest quality.

8. Data Management
Why is data management difficult and expensive?
• Volume of data is increasing exponentially.
• Data is scattered throughout the organization.
• Data is created and used offline without going through
quality control checks.
• Data may be redundant and out-of-date, creating a huge
maintenance problem.

9. Data Management
Current key issues
 Master data management (MDM): Processes to integrate
data from various sources and enterprise apps in order to
create a unified view of the data.
 Document management system (DMS): Hardware and
software to manage, archive, and purge files and other
electronic documents (e-documents).
 Green computing: Efforts to conserve natural resources
and reduce effects of computer usage on the
environment.

10. IT at Work 3.1 – Healthcare Sector
Data Errors Cost Billions of Dollars and Put Lives at Risk
 Every day, healthcare administrators and others throughout
the healthcare supply chain waste 24% --30% of their time
correcting data errors.
 Each incorrect transaction costs $60 to $80 to correct.
 About 60% of all invoices among supply chain partners have
errors, and each invoice error costs $40 to $400 to reconcile.
 Each year, billions of dollars are wasted in the healthcare
supply chain because of supply chain data disconnects.

11. IT at Work 3.1 (continued)
Data Errors Cost Billions of Dollars and Put Lives at Risk
Benefits from data synchronization in the healthcare sector
and supply chair:
• Easier and faster product sourcing because of accurate
and consistent item information
• Significantly reduces the amount of fraud or unauthorized
purchasing
• Reduces unnecessary inventories
• Lowers prices because purchase volumes became
apparent
• Improves patient safety

14. Data principles
 Principle of diminishing data value. The more
resent the information, the more valuable it is
 Principle of 90/90 data use: 90% of data is
seldom accessed after 90 days.
 Principle of data in context. Investment in DM
infrastructure may be huge.

19. Limitations of the File Environment
 When organizations began using computers, they started with
one application at a time, usually accounting, billing, and payroll.
Each app was designed to be a stand-alone system, which led to
data problems.
 Data problems with a file environment:
• data redundancy
• data inconsistency
• data isolation
• data security

20. • Stand-alone systems result in data
redundancy, inconsistency, and isolation.
•Database management systems helped solve the
data problems of file-based systems.

22. 3.3 Database Management Systems (DMBS)
 Numerous data sources
• clickstream data from Web and e-commerce applications
• detailed data from POS terminals
• filtered data from CRM, supply chain, and enterprise
resource planning applications
 DBMS permits an organization to centralize data, manage
them efficiently, and give application programs access to the
stored data.

23. 2 types of databases:
a) Centralized database
b) Distributed database with
complete or partial copies
of the central database in
more than one location

24. Functions of a Database Management System (DBMS)
 Data filtering and profiling: Inspecting the data for
errors, inconsistencies, redundancies, and incomplete
information.
 Data quality: Correcting, standardizing, and verifying the
integrity of the data.
 Data synchronization: Integrating, matching, or linking data
from disparate sources.
 Data enrichment: Enhancing data using information from
internal and external data sources.
 Data maintenance: Checking and controlling data integrity
over time.

25. 3.4 Data Warehouses, Data Marts, and
Data Centers
 Data warehouse: a repository in which data are organized so that
they can be readily analyzed using methods such as data
mining, decision support, querying, and other applications.
• enable managers and knowledge workers to leverage enterprise data to
make the smartest decisions
• enable OLAP (online analytic processing)
 Data marts: designed for a strategic business unit (SBU) or a single
department.
 Data centers: facilities containing mission-critical ISs
and components that deliver data and IT services to the enterprise.

27. Characteristics of a data warehouse
 Organization. Data are organized by subject (e.g., by
customer, vendor, product, price level, and region), and contain
information relevant for decision support only.
 Consistency. Data in different operational databases may be encoded
differently. For example, gender data may be encoded 0 and 1 in one
operational system and “m” and “f” in another. In the warehouse they will
be coded in a consistent manner.
 Time variant. The data are kept for many years so they can be used for
trends, forecasting, and comparisons over time.
 Nonvolatile. Once entered into the warehouse, data are not updated.
 Relational. Typically the data warehouse uses a relational structure.
 Client/server. The data warehouse uses the client/server architecture
mainly to provide the end user an easy access to its data.
 Web-based. Today’s data warehouses are designed to provide an efficient
computing environment for Web-based applications (Rundensteiner et.
al., 2000).

29. Building an Enterprise Data Warehouse (EDW)
A company that is considering building a DW first needs to
address a series of basic questions to avoid a failure:
• Does top management support the DW?
• Do users want access to a broad range of data
• Do users want data access and analysis tools?
• Do users understand how to use the DW to solve business
problems?
• Does the unit have one or more power users who can
understand DW technologies?

31. Suitability
Data warehousing is most appropriate for organizations
that have some of the following characteristics:
 End users need to access large amounts of data
 Operational data are stored in different systems
 The organization serves a large, diverse customer base
 The same data are represented differently in different systems
 Extensive end-user computing is performed

34. Unstructured business records
 Businesses generate volumes of documents, messages, and
memos that, by their nature, contain unstructured content
that cannot be put into a database.
 Many of these materials are business records that must be
retained and made available when requested by
auditors, investigators, the SEC, the IRS, or other authorities.
 To be retrievable, business records must be organized and
indexed.
 Records are not needed for current operations or
decisions, are archived—moved into longer-term storage.

3-34

35. Business Value of E-Records Management
 Companies need to be prepared to respond to an
audit, federal investigation, lawsuit, or other legal action
against it.
• Examples of lawsuits: patent violations, fraud, product safety
negligence, theft of intellectual property, breach of contract, wrongful
termination, harassment, and discrimination
 E-discovery is the process of gathering electronically stored
information in preparation for trial, legal or regulatory
investigation, or administrative action as required by law.
• When a company receives an e-discovery request, the company must
produce what is requested—or face charges of obstructing justice or
being in contempt of court.

3-35

36. Companies have incurred huge costs for not
responding to e-discovery
 Failure to save e-mails resulted in a $2.75 million fine for
Phillip Morris.
 Failure to respond to e-discovery requests cost Bank of
America $10 million in fines.
 Failure to produce backup tapes and deleted e-mails resulted
in a $29.3 million jury verdict against UBS Warburg in the
landmark case, Zubulake v. UBS Warburg.
