nd it is
growing in functionality. As we take DB2 into new business areas, we
need to allow for a change in application processing. More and more, we are seeing requirements to allow
for processing of nonstandard data (such as image and video), to allow ve
ry complex operations to be
performed against the data (such as data mining operations), to be able to process very large amounts of
data (greater than 1 terabyte), and to support e
business solutions (24x7 data availability).

A little more about relational database technology

Chances are, if you’re hired by IBM, you’ll work on one of our relational database pr
oducts, such as DB2,
DB2 Warehouse Manager, or another DB2
related product. This article sheds a little light on some of the
basic concepts of relational databases.


By Michael Morrison

management system

) consists of a collection of interrelated data and a set of

programs to access those data.” [1] The collection of data is referred to as a
. If you have a couple
dozen to a few hundred pieces of data, you can fairly easily keep track of them and m
anage them using any
number of technologies that predate databases: indexed data files, flat data files, or even index cards and a
pencil! But when you have thousands or millions of pieces of data, those technologies are no longer as
efficient or convenien
t as a database.

By using a database management system, you gain the following benefits:

Elimination of redundant data
: By keeping your data in one place, instead of in files that are specific to
each application program, you can eliminate redundant data
, which saves space and access time, and
increases the overall accuracy of your data.

Increased data integrity
: A DBMS can enforce rules for the data, such as ensuring that an account
balance never falls below some amount. It’s more efficient to have the D
BMS enforce such rules
centrally rather than to have each application program enforce them separately.

Guaranteed all
nothing updates
: A DBMS guarantees that each update request either succeeds
completely or fails

it cannot partially succeed. For exampl
e, when you transfer $100 from your savings
account to your checking account, you wouldn’t want the money to be removed from one account
without also being added to the other.

Concurrent access to data
: A DBMS allows multiple programs to access the data at

one time, while
guaranteeing all
nothing updates.

Secure data
: A DBMS can manage the users and programs that are allowed to access the data,
whereas flat files are extremely difficult to manage for security.

A database is composed of three levels of d
ata abstraction:

The physical level describes

the data is stored in the file system.

The logical level describes

is stored in the database, including relationships between the data.

The view level describes parts of the database that are of in
terest to particular application programs.


There are four major models for designing a database:


model uses tables to represent the data and the relationships among the data. Each table
has one or more columns and zero or

more rows.


model uses instance variables within object instances, which are accessible through
methods defined for the object.


model uses a tree structure to represent the relationships among the data.


odel uses an arbitrary graph structure to represent relationships.

The most popular model is the relational model. In this model, all of your data is stored in a database, which
is comprised of tables. Each table contains data about a specific part of you
r business. For example, a
bank would have a customer table that contains columns for name, address, account number, and so on.
Each row in the table defines one customer. The bank would also have other tables, such as savings
account, loan, and so on, tha
t, when taken together, define the bank's business.


To access and update a database, you use a special programming language. For relational databases, this
language is Structured Query Language (SQL). SQL is a standard language used by a
ll DBMSs, but each
database vendor can add extensions to the language for their database.

There are two kinds of statements in SQL: statements for defining the database and statements for
manipulating data in the database. Examples of definition stateme
nts include
create table
drop table
alter table
. Examples of manipulation statements include
, and
. Each of
these statements has a specific syntax that defines how it affects the database. For example, the

t has the form:

column1, ..., columnN

table1, ..., tableN


This statement retrieves data from the database, but does not modify the data. It retrieves one or more
columns of data from one or more tables when the defined expres
sion is true.

Here is a more concrete example: To retrieve loan numbers from a loan table for all bank branches named
“Perryridge” where the amount of the loan is greater than $1000, you would use the following


select loan



where branch
name = "Perryridge"

and amount > 1000



is a

of program execution that accesses and possibly updates various data items.” [1]

A transaction has the following properties:

: Either a
ll of the operations of a transaction are reflected in the database, or none of them are.

: A transaction cannot corrupt the consistency of the database.

: Executing transactions in parallel must be equivalent to running them one after

: After a transaction completes successfully, the changes it made to the database must
persist, even if there are system failures.

In order to provide these properties for transactions, a transaction that updates the database must

its changes when it completes or

its changes if there is some problem. Changes for committed
transactions appear in the database, but changes from aborted transactions are
rolled back

and do not
appear in the database.


Databases are

traditionally used in online transaction processing (OLTP) environments, that is,
environments that are primarily oriented toward transactions. A classic example of an OLTP environment is
a bank, where every transaction is an update to (or query of) a ban
k account.

Because databases contain the critical data that runs a business, companies want to maximize the use of
that data. Some of the uses for databases include:

Data mining
: The process of extracting previously unknown, valid, and actionable informa
tion from large
databases and then using that information to make crucial business decisions. [2]

Data warehousing
: The storage of subject
oriented, integrated, time
variant, and nonvolatile data in support
of management. [2][3] A data warehouse often inc
ludes subsets of data from multiple databases, based on
the subject or time frame required.

support systems and analytical processing
: The process of analyzing data to spot trends,
pinpoint problems, and make more intelligent business decisions.
[4] Decision
support systems often
include data
mining applications and data warehouses.

Distributed data
: Storing data in multiple physical locations to enable distributed (rather than centralized)
queries and local access to data rather than remote acce
ss. [4] Companies also distribute their data for
recovery purposes.

Mobile data access
: Allowing occasionally connected computers (such as laptop computers and personal
digital assistants) to access enterprise data. [1] The mobile computer can ei
ther connect to a central
database or it can copy portions of the database to local storage.

Multimedia data
: Relational databases can store more than letters and numbers. Many DBMSs can store
binary data, such as multimedia files, geographic maps, and ot
her binary objects.

Web data access
: By combining all of the above uses of databases with the distributed access provided by
the World Wide Web, businesses are making much of their data directly available to their customers.
DBMS vendors are also “Web en
abling” their databases, so that they can more easily use Web files and

: DBMS vendors are beginning to add support for this relatively new text
up language, based on
HTML, so that application programs can store shared data in a common format.
