7. JAVA
Based on C++
Sun introduced in May 1995
World Wide Web caused immediate interest
Object Oriented Language
Achieves modularity through the use of Classes and
Methods

8. JAVA
Classes and Methods may be programmer defined
The Java Class Library or Java API provides
predefined Classes and Methods
Example:
The Math Class provides several mathematical
methods such as:
 Abs (x)
 Min (x,y)

9. JAVA
 //a simple Java program which defines class Welcome,
and has only one method
 Import java.applet.Applet; //imports the Applet class
 Import java.awt.Graphics //imports the Graphics
class
 Public class Welcome extends Applet {
 Public void paint( Graphics g )
 {g.drawstring( “Welcome to Java Programming”, 25,
25 );}
 }

10. JAVA
Five phases to execute program:
 Edit => save as Welcome.java
 Compile => javac Welcome.Java creates Welcome.class
 Create HTML file which includes applet called
Welcome.class
 Load => user’s browser will load Welcome.html file
 Verify => verifies that Welcome.class applet does not
violate Java security
 Execute => java interpreter within user browser
executes Welcome.class applet

11. JAVA
Network Delivered Functionality
Java Applet is stored on Server, not on client
Client needs only a Java supported browser to
execute applet within Server html file
Client does not need Java installed locally
Demonstrates power of Java:
 Ability to provide network delivered functionality

12. JAVA BEANS
Reusable software components written using Java.
Allows code to be shared beyond one platform, one
architecture (distributed systems).
“Write Once, Run Anywhere”

13. JAVA BEANS
Allows applications to be assembled, rather than
coded in the classical monolithic style.
Embraces internet and addresses Client/Server
deployment/ maintenance issues via “thin-client”.
Device independent. Supported on Mainframes, PCs,
Network Computers, cellular phones, PDAs.

14. BEAN FEATURES
Introspection - builder tool can automatically
analyze how a bean works
Customization - ability to customize appearance and
behavior of a bean
Events - enables connection and communication
between Beans.
Properties - enables customization of Beans.
Persistence - Storing of data across sessions.

15. ENTERPRISE JAVA BEANS
Model for the development and deployment of
reusable Java Server components.
API specification for building scalable, distributed,
component based, multi-tier applications.
First released to public March of 1998.

16. ENTERPRISE JAVA BEANS
Concerned with “Server-Side” portion of business
applications.
Maps communication among components to
underlying protocols such as CORBA (Component
Object Request Broker Architecture) and IIOP
(Internet InterORB Protocol).
Transactional perspective.

17. ENTERPRISE JAVA BEANS
Provides typically application server functions:
 start, commit/rollback, security, database access
Designed to be layered on top of existing IT systems.
EJB Servers available in 1998
 BEA WebLogic Tengah
 IBM WebSphere Advanced Edition
 Oracle Application Server

18. ENTERPRISE JAVA BEANS
Additional EJB Servers expected from:
 Fujitsu
 Informix
 Netscape
 Sun
 Sybase

20. DATA WAREHOUSING
PROOF OF PERFORMANCE AND SCALABILITY (POPS)
TEST
 Standard test performed by Informix
 Supermarket
 19,000 products
 3.6 million transactions per day
 35 ongoing sales promotions
 Two fact tables/five dimension tables
 Sun 10000 Starfire and Informix Red Brick Warehouse
performance
 300 GB of raw data was query-ready in five days
 Included all of ETT process

21. WEB-ENABLED DATA WAREHOUSING
NEED FOR WEB-ENABLED DATA
WAREHOUSING
 Increased demands on IT Departments for reports and
information
 Outside access for customers
 Outside access for mobile users

22. WEB-ENABLED DATA WAREHOUSING
ADVANTAGES (WHAT WAS ACCOMPLISHED)
 Better customer support / lower cost
 More use of the data warehouse
 Better understanding of data by end users
 More sophisticated queries
 Diminished need to extend corporate networks
 Simplified system administration
 Increased opportunity to outsource

23. WEB-ENABLED DATA WAREHOUSING
HOW COSTS ARE CUT
 Less expensive desktop computers
 Use of free web browsers
 Less training costs
 Lowered communication cost
 Lowered application software licensing cost
