Domino Query Language (DQL) is a facility running in Domino core allowing for a terse shorthand syntax for finding documents according to a wide variety of complexity of terms. It leverages existing design elements without the need to write detailed code to access them.
Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.
Domino® Designer includes two types of design elements to assist you in managing data contained in DB2® enabled Notes® databases:
