GLOSSARY OF TERMS

Cascading style Sheet ( CSS ): is a web page derived from multiple sources with a defined order of precedence where the definitions of any style element conflict.

JAVA 2 Platform Enterprise Edition (J2EE): is Java-based software infrastructure. This is a standardized set of infrastructure software components written in the 'run-anywhere' Java programming language.

JavaBeans: is an object-oriented programming interface from Sun Microsystems that lets you build re-useable applications or program building blocks called components that can be deployed in a network on any major operating system platform.

XML (Extensible Markup Language): is a flexible way to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere.

XSL (Extensible stylesheet Language): formerly called Extensible style Language, is a language for creating a style sheet that describes how data sent over the Web using the Extensible Markup Language (XML) is to be presented to the user.

Weblogic: is a server software application that runs on a middle tier, between back-end databases and related applications and browser-based thin clients.

EMPLOYMENT  AND   OUTLOOK

Nationally, the number of Java Developers employed in 2009 is unknown. Employment is expected to increase as the demand for highly qualified computer professionals' increases.

Employment in data processing firms is not expected to rise as fast as in recent years. Technology has reduced both the size and cost of computer hardware, bringing computer systems within reach of small businesses. As more businesses install their own computers, reliance on data processing firms will decline. Opportunities will be best for individuals with 2- or 4-year college degrees.

The number of Java Developers employed in Michigan is unknown. The development of new and emerging technologies such as developing technology for mobile devices will spur growth in this occupation.

The best opportunities will be for those with a bachelor's degree in computer science or computer engineering, and those who are familiar with a variety of programming languages, particularly those that apply to object-oriented programming, CASE, fourth-generation languages, UNIX, open systems relational databases, and client/server architecture.

Those with "soft skills" in addition to technical skills are in demand as well as those with the ability to analyze business problems and develop comprehensive web-based applications to improve overall efficiency.  Java Developers who are proficient in Sequel Query Languages (SQL) on an Oracle database platform, Cascading style Sheets ( CSS), JavaBeans, Perl, Weblogic Applications Server, XML (Extensible Markup Language) and XSL (Extensible stylesheet Language) will find employment opportunities more favorable in a highly competitive market.
