information locally. Additionally, a host of other vendors (including IBM) brought us SQL. Because it was done by committee, SQL became the de facto standard for working with data and databases. In the 90s, Microsoft popularized the client/server platform. This seemed like a good idea, and it certainly provided an example for so-called user-friendly ways of combining business transactions and computers. The problem was distribution. If an organization had 1000 workstations, it would be difficult if not impossible to maintain each of these workstations at the same level of software. In the 2000s, Sun Microsystems and other vendors brought us JEE. Once again, a committee has created a standard way to architect business processes that run on almost any platform. This is powerful, because these computer classes are portable and interoperable. From a development perspective, these major revolutions involved only SQL and JEE, because these are standards to which almost everyone has adhered. Just as SQL defines the standard for querying multiuser relational databases, JEE defines the standard for developing multi-tier enterprise applications. JEE, much like the SQL paradigm, simplifies enterprise applications by basing them on standardized, modular components; by providing a complete set of services to those components; and by handling many details of application behavior automatically, without the need for complex programming. JEE takes advantage of many features of standard Java, such as write once, run anywhere portability, the JDBC API for database access, RMI, CORBA technology for interaction with existing enterprise resources, and a security model. Building on this base, JEE adds support for EJB components, the Java Servlets API, JSP, and Extensible Markup Language (XML) technology. The JEE standard includes complete specifications and compliance tests to ensure portability of applications across the wide range of existing enterprise systems capable of supporting JEE. This portability was also a key factor in the success of SQL. Standards such as SQL and JEE help enterprises gain competitive advantage by facilitating quick development and deployment of custom applications. Whether they are internal applications for staff use or Internet applications for customer or vendor services, this timely development and deployment of an application is key to success. Portability and scalability are also essential for long-term viability. For example, our company has ported a single SQL application database using five different vendors: Oracle, Sybase, Informix, Microsoft SQL Server, and IBM DB/2. Enterprise applications must scale from small working prototypes and test cases to complete 24 7, enterprise-wide services that are accessible by tens, hundreds, or even thousands of clients simultaneously. In the global finance market, 24 7 is especially important.

Multi-tier applications are difficult to architect. They require merging a variety of skill sets and resources, perhaps also including legacy data and legacy code. In today s heterogeneous environment, enterprise applications must integrate services from a variety of vendors with a diverse set of application models and other standards. Existing daily cycle applications at Merrill Lynch, for example, use all of the database vendors in addition to legacy databases such as IDMS, ADABAS, IMS, and a host of others. Industry experience shows that integrating these resources can take up to 50 percent of application development time. JEE will hopefully break the barriers inherent to current enterprise systems. The unified JEE standard permits an API set that in full maturity will wrap and embrace existing resources required by multi-tier applications with a unified, componentbased application model. This will initiate the next generation of components, tools, systems, and applications for solving the strategic requirements of the enterprise. Figure 2-6 provides a glimpse of how a JEE server fits into the frame of a Netenabled enterprise application. The good news is that it can salvage and extend life to legacy systems that have been in production and are sensitive to change. Although Sun Microsystems invented the Java programming language, the JEE standard represents collaboration between leaders from throughout the enterprise software arena. Partners include OS and database management system providers IBM and Microsoft, middleware and tool vendors BEA WebLogic and IBM WebSphere, and vertical market applications and component developers. Sun has defined a robust, flexible platform that can be implemented on the wide variety of
