In a set associative cache, there are a fixed number of locations (at least two) where each block can be placed. A set associative cache with n locations for a block is called an n-way set associative cache. An n-way set associative cache consists of more than one set, each of which consists of n blocks. A block can be placed in any location (element) of that set. Increasing the associativity level (number of blocks in a set) increases the cache hit rate. See also cache, cache locality, false sharing, write-invalidate, write-update.

A DTD specification that defines an element as containing a mixture of text and one more other elements. The specification must start with #PCDATA, followed by diverse elements, and must end with the "zero-or-more" asterisk symbol (*).

In a JMS publish/subscribe messaging system, a subscription that continues to exist whether or not there is a current active subscriber object. If there is no active subscriber, the JMS provider retains the subscription's messages until they are received by the subscription or until they expire.

A distinct, individual item that can be included in an XML document by referencing it. Such an entity reference can name an entity as small as a character (for example, <, which references the less-than symbol or left angle bracket, <). An entity reference can also reference an entire document, an external entity, or a collection of DTD definitions.

In a concurrent environment, the first process to access data for writing has exclusive access to it, making concurrent write access or simultaneous read and write access impossible. However, the data can be read by multiple readers.
