Installation Guide
protocol
A set of rules that govern the transmission and reception of data.
put
A request to store a message in a queue. Compare to get.
regular expression
Strings which express rules for string pattern matching.
rule
A rule is uniquely defined by its application group, message type, and rule name. It contains
evaluation criteria (a rules expression) and is associated with subscriptions to perform if the rule
evaluates to true. Rules also have permissions that determine user access.
scalable, scalability
Changeable in size and configuration. The ability to expand, implying minimal procedural change
to accommodate growth.
server
A computer that, through its network connections, carries out parts of computing tasks for other
networked computers.
shared subscription
A subscription that is associated with more than one rule. This subscription will only be retrieved
once by the Rules APIs even if multiple associated rules evaluate true.
subscription
A subscription is uniquely identified by its application group, message type, and subscription name.
It contains actions with options and can be associated with one or more rules. Subscriptions also
have permissions that determine user access to change the subscription definition.
synchronous
In electronic messaging, a method of operation in which sender and receiver applications are tightly
coupled and dependent. The receiver must answer the sender’s message immediately with a well-
defined response; the sender must wait for the receiver’s response before proceeding to the next
operation. Compare to asynchronous.
table
A database remembers relationships between pieces of information by storing the information in
tables. The columns and rows in each table define the relationships in a highly structured way. We
can classify tables by function into two types: support tables and data tables. Most tables fit into
only one category, but some can serve as both support and data tables.
A support table stores information that changes infrequently and functions as a list from which you
make selections.
tag
A set of bits or characters that identify various conditions about data in a file. In New Era of
Networks Formatter, a standard value indicating the field’s name.
