ABOUT SUN • Founded in 1982 • “The network is the computer” has been the guiding philosophy

PRODUCT OFFERINGS • JAVA • Cross-platform performance • Embedded in portable electronic products • Java is a key to Sun’s success

PRODUCT OFFERINGS • SOFTWARE • Internet services • Network connectivity • Security • Network management • Application servers

PRODUCT OFFERINGS • HARDWARE • Desktop systems • Servers • Network connectivity • Data Warehousing • Peripherals

BUSINESS PRINCIPLE • MULTI-VENDOR SOLUTIONS • Teams with software vendors • Brings Java and computing platform to the partnership • Business partners • Sun and Informix • Sun and Netscape

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

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)

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 );} • }

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

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

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

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.

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.

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.

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.

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

ENTERPRISE JAVA BEANS • Additional EJB Servers expected from: • Fujitsu • Informix • Netscape • Sun • Sybase

DATA WAREHOUSING • COMPONENTS • SunEnterprise 10000 “Starfire” server • IBM DB2 Universal Database • Sun StorEdge Arrays • Sun StorEdge Volume Manager • RAID Manager • Solaris Operating System

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

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

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

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
