Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
An entity that provides enterprise information system-specific functionality to its clients. Examples are a record or set of records in a database system, a business object in an enterprise resource planning system, and a transaction program in a transaction processing system.
Industry:Computer
Write policy for maintaining coherency between cache and main memory. Write-back (also called copy back or store in) writes only to the block in local cache. Writes occur at the speed of cache memory. The modified cache block is written to main memory only when the corresponding memory address is referenced by another processor. The processor can write within a cache block multiple times and writes it to main memory only when referenced. Because every write does not go to memory, write-back reduces demands on bus bandwidth. See also cache, coherence, write-through.
Industry:Computer
An entity bean that can handle multiple simultaneous, interleaved, or nested invocations that will not interfere with each other.
Industry:Computer
An act whereby one entity assumes the identity and privileges of another entity without restrictions and without any indication visible to the recipients of the impersonator's calls that delegation has taken place. Impersonation is a case of simple delegation.
Industry:Computer
An enterprise bean that represents persistent data maintained in a database. An entity bean can manage its own persistence or can delegate this function to its container. An entity bean is identified by a primary key. If the container in which an entity bean is hosted crashes, the entity bean, its primary key, and any remote references survive the crash.

World Wide Web Consortium. The international body that governs Internet standards. Its Web site is http://www.w3.org/.
Industry:Computer
An enterprise bean that is an asynchronous message consumer. A message-driven bean has no state for a specific client, but its instance variables can contain state across the handling of client messages, including an open database connection and an object reference to an EJB object. A client accesses a message-driven bean by sending messages to the destination for which the bean is a message listener.
Industry:Computer
An acronym for application-specific integrated circuit. Any of the functionally complex chips in the OPL hardware design.
Industry:Computer
Wiring UI components to back-end data sources such as backing bean properties.
Industry:Computer
In a bus-connected multiprocessor system, processes or threads communicate through a global memory shared by all processors. This shared data segment is placed in the address space of the cooperating processes between their private data and stack segments. Subsequent tasks spawned by fork() copy all but the shared data segment in their address space. Shared memory requires program language extensions and library routines to support the model.
