Virtual DataPort is a global solution for heterogeneous and dispersed data source integration in real time.

Virtual DataPort uses VQL (Virtual Query Language) as Data Definition and Data Manipulation Language. VQL allows creating and updating the elements that constitute the system catalog, as well as querying and updating the unified information views. VQL is highly compatible with SQL but it also includes specific constructions to deal with the particularities of a virtual information integration system.

This document describes VQL and how to use it to perform Virtual DataPort administration tasks. It is important to remark that it is not usually needed to write VQL scripts manually. The Virtual DataPort Administration Guide describes how to perform the most usual administration tasks using the Administration Tool.


We strongly recommend using the Administration Tool for all the administration tasks.
