abstract process

. A business protocol description document that tells your business partners what a process will look like when it runs. It outlines the steps of process without actually filling in all the actions and data required for a running process. See Executable Process.

connection pool

. As a requestor application opens a connection to a data source and then releases it, the connection remains open for reuse by another requestor. In this way, a pool of open connections is built, with complete authentication information and connection properties. If available, the connection requests to the same data source are satisfied from the pool rather than by making a hard connection on demand, which enhances performance of the requests.

container

. A structured activity that sets rules and conditions for executing child activities; for example, a sequence organizes activities to execute in an ordered list.

deadline or duration

. The settings for OnAlarm events in a pick activity, event handler, or task.

join condition

. A Boolean expression indicating the status of a link targeting an activity.

my role

. A child element of a partner link. A partner link defines "my role" as the role played by the business process. The service called for receive, pick and event input messages is the service fulfilling my role.

partner

. A unique collection of partner links.

partner link

. Describes the roles that a process and service play as well as what data they can manipulate in that role. A partner link is defined by its partner link type.

partner link type

partner role

. A child element of a partner link. A partner link defines partner role as the role played by an invoked service.

TII

. Text information item. A sequence of zero or more Character Information Items, according to document order; as such, a TII is not manifested in and of itself directly in XML serialization. When mapped to the XPath 1.0 model, it generalizes a string object (which has zero or more characters) and text node.

URL

. A web site address, such as http://www.informatica.com.
