Organized Data
and Information
Data
• Data
– A necessity for almost any enterprise to carry out
its business. Consists of raw facts, and when
organized may be transformed into information.
• Database
• A collection of data organized to meet users’
needs
Data Management
• In order to manage data it must be organized.
• It is organized in a hierarchy.

The Hierarchy of Data
Database
A collection of integrated and
related files.
File
A collection of related records.
Record
A collection of related fields.
Field
A group of characters.
Character
Basic building block of information,
represented by a byte.
How Characters are Stored
Codes for Storing Data
ASCII
• American Standard Code for Information
Interchange.
• 8 bit code. (256 characters can be represented).
• In the early years of computers, it was the most
popular code but it was limited to how many
characters it could represent. ASCII is still very
much used today but it has be extended from 8 bits
to 16 bits. With 16 bits, over 65,536characters can
be represented.

Codes for Storing Data
UNICODE
• UNICODE: Universal Code.
• Today, it is the most popular code.
• Used by most computer manufactures.
• 16 bit code. (65,536 characters can be represented)
• A 16 bit code will allow for other languages to
be represented in the code, not just English.

The Traditional Approach to Data Management
Data Files
Application
Program
Reports
• The Traditional Approach
– Separate files are created and stored for
each application program.
– Very common from the 50’s through the
80’s.

PROBLEMS
(1) DATA REDUNDANCY
•Same data stored on different files.
•Name is on checking, savings, and loan files.
•Address is on checking, savings, and loan files.
•Telephone number is on checking, savings, and loan files.

PROBLEMS
DATA REDUNDANCY CAUSES:
•Unnecessary data entry.
•Duplicated data on one file may not get changed on another file
during an update or deletion.
•Leads to a lack in DATA INTEGRITY.

•Data redundancy leads to a lack of data integrity.
•Lack of data integrity = errors in database

PROBLEMS
(3) LACK OF DATA INTEGRATION
•With separate file systems, it is difficult to produce reports
which require data from separate file systems.
•EXAMPLE: The bank manager might want a report showing the names
of customers who use all the bank's services: checking, savings and loans.
•In order to collect this information for a report, a separate computer
program would need to be written and this take time.

PROBLEMS
(4) PROGRAM-DATA DEPENDENCE
•If the size of a field in a record changes, all the programs which
access that record must be modified.
•EXAMPLE: When ZIP codes changed from 5 digits to 9
digits, all programs which accessed ZIP codes had to be
modified.
Note: When the ZIP code changed, millions of
programs needed to be changed in
corporations, governments, etc.

The Database Approach
• The Database Management System Approach
– A pool of related data is shared by multiple application
programs. Rather than having separate data files, each
application uses a collection of data that is either joined
or related in the database.
– A DBMS “knows” everything about the data on the
hard storage drive/s, and has complete control over it.

Advantages to the 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
• A framework for program development
• Better overall protection of the data
• Shared data and information resources
Disadvantages to the Database Approach
• Increased vulnerability. Unauthorized people hack into
databases on a regular bases.
• Foolishly, employees place databases on their laptops which
are stolen when left in cars or unattended at coffee shops.

Kensington Lock
• Great for coffee shops
• The cable is retractable. Just
wrap the cable around a table
post and into the Kensington port on your
computer; then lock the cable into the port.

DATA MODELING
• This is map or diagram of entities and their relationships.
• These maps or diagrams show the how the database is organized.
• A popular diagramming technique is called “entity-relationship
diagram.”
• A MODEL of the database is constructed before the actual
database is designed. One popular modeling method is called
an entity-relationship diagram.

A Relational Data Model
• Relational Data Model
– All data elements are placed in twodimensional tables, called relations, that
are the logical equivalent of files.

Relational Database Terms
Joining
– Data manipulation that combines two or more tables.
– These three tables can be joined using a common field such as Dept.
number.
– Example: Using Project number (155) we can find out
the description of the project and for what department the
project was conducted.
This can be done easily even though the data is within two
separate files.
– See the next slide to see how easy joining can be done using
a query language called SQL. (Pronounce S-Q-L or “sequel”)
SQL is in all database management systems, including Access.

SQL EXAMPLE:
•This example shows how to join two
tables using SQL in order to find
the Project name and the
Department in which the Project
was conducted.
• Note that the Description of the
project (Payroll) was in the Project
table and the Dept Name
(Accounting) was in the
Department table.
• The tables were joined using
the Dept Number field.

• AUTOMATED discovery of patterns and relationships
in a data warehouse.
• Uses advanced statistical techniques and machine

Data Modeling and Database
Models
• Data Model
– A map or diagram of entities and their
relationships.
• Enterprise Data Modeling
– Data modeling done at the level of the
entire organization.
• Entity-Relationship (ER) diagrams
– A data model that uses basic graphical
symbols to show the organization of and
relationships between data.

• PRIMARY KEYS: Each table has a UNIQUE identifier called a primary key.
•Customer ID
•Order ID
•Book ID
•Primary Keys are used to identify a record in a database, much like a SSN is

DATABASE TERMS
•FOREIGN KEYS: The Orders Table has two foreign keys.
•Foreign Keys are fields with the same (but could be different) names as the
PRIMARY KEY in other tables. For example, Customer ID in the Orders Table is
the name of the PRIMARY KEY in the Customers Table. And, Book ID in the
Orders Table is the name of the PRIMARY KEY in the Books Table.
Every order that a customer places will cause a new record to be placed in the
Orders Table. That record will contain the Customers ID number, the Book ID
Number and the Order Date. The function of the Orders Table is to track orders.
