A CDE Definition
A Java EE benchmark from Sun for measuring the performance of EJB containers. It is designed to measure internal functions such as memory management, connection pooling and caching, rather than the graphical interface or database I/O. The ECperf workload focuses on manufacturing, supply chain management and order/inventory processing. Results are measured in Benchmark Business Operations Per Minute (BBops/min), which is the combination of the total number of customer transactions and manufacturing workorders processed in one minute. See Java EE.
(Java Platform, Enterprise Edition) An application software platform from Oracle based on the Java programming language. Originally developed by Sun, which Oracle acquired in 2010, Java EE services are performed in the middle tier between the user's machine and the enterprise's databases and legacy information systems. Java EE comprises a specification, reference implementation and set of testing suites. Its core component is Enterprise JavaBeans (EJBs), followed by JavaServer Pages (JSPs) and Java servlets and a variety of interfaces for linking to the information resources in the enterprise.
The Java EE interfaces include JDBC for databases, JNDI for directories, JTA for transactions, JMS for messaging, JavaMail for email systems and JavaIDL for CORBA connectivity. Java Connectors are interfaces to a variety of legacy applications.
In December 1999, J2EE Version 1.2 was introduced as the first formal release of the Enterprise specification. In 2005, Sun renamed the Java Platform by dropping the 2 (J2EE 5.0 became Java EE 5.0). See EJB, JSP, servlet, Java Connector, Java SE and Java ME.
