You can browse the contents on the left or use the search box at the top to search specific topics and also, to search on the entire Denodo Community.
Getting Started¶
If you are new to Denodo, here are some resources that are useful:
Watch the video Data Virtualization: An Overview: a high level of explanation of what Data Virtualization is and what Denodo does.
Denodo Express: a free version that includes most of the features of the Denodo Platform. You can install it on your machine, an AWS EC2 instance…
You can request a 30-day free trial of Denodo Professional (find below the differences between Denodo Professional and the different Denodo Platform bundles).
Test Drives: with the Test Drives you can quickly and easily explore the benefits of using data virtualization with Denodo Platform on the cloud. It is free of charge for demonstration, education and evaluation purposes. You do not need to install anything; everything is provisioned automatically for you on the cloud.

What is Denodo?¶
Data virtualization is a logical data layer that integrates all enterprise data siloed across the disparate systems, manages the unified data for centralized security and governance, and delivers it to business users in real time. Data virtualization is the modern approach to data integration. Unlike ETL solutions, which replicate data, data virtualization leaves the data in source systems, simply exposing an integrated view of all the data to data consumers. Find more information about this at https://www.denodo.com/data-virtualization/benefits.
The Denodo Platform is the leader in Data Virtualization.
These guides explain how to install and use:
The Denodo Platform and its FeaturePacks
Denodo Professional
Denodo Standard
Denodo Express
They are all built on the same engine but Denodo Professional and Denodo Express have some restrictions (see Denodo Platform - Subscription Bundles and Restrictions of Denodo Express).
Modules of the Denodo Platform¶
The Denodo Platform has these modules:
Virtual DataPort |
The main module of the Denodo Platform. This is the module where developers create “virtual views” that integrate data from multiple sources: databases, SAP servers, XML files, JSON files, CSV files, etc. Virtual DataPort provides several ways to query these virtual views:
|
Data Catalog |
Aimed at business users, to query and search data and metadata of your organization. |
Scheduler |
Enables you to schedule jobs to interact with the other modules of the Denodo Platform. For example, send queries to Virtual DataPort at a particular moment and process its result. |
Diagnostic and Monitoring Tool |
Provides two main features:
|
Solution Manager |
The Solution Manager helps you manage your deployment of Denodo servers. It consists of two components:
|
These modules are provided in two installers (i.e. two different packages you have to download from the Denodo Support Site):
The installer of the Solution Manager.
The installer of the Denodo Platform, Denodo Professional or Denodo Express. These include Virtual DataPort, Data Catalog, Scheduler, and the Diagnostic and Monitoring Tool.
That is, you will have to perform at least two installations: one installation of the Solution Manager and one or more installations of the Denodo Platform. Unless you are doing an evaluation, you will install the Solution Manager in one computer and the installation of each Denodo Platform in other computers.
Installation¶
The Solution Manager Installation Guide explains how to install the Solution Manager.
The Denodo Platform Installation Guide explains how to install the Denodo Platform.
Structure of the Documentation¶
Virtual DataPort¶
The documentation of Virtual DataPort is divided in three documents:
Virtual DataPort Administration Guide

It explains how to configure and manage the Virtual DataPort server.
Virtual DataPort Developer Guide
How to access a Virtual DataPort server using the Denodo JDBC and ODBC drivers to query Denodo from your applications.
How to use the API provided Virtual DataPort to develop custom extensions: stored procedures, wrappers to new sources, functions, security policies and filters.
-
It is a reference manual for the VQL language (Virtual Query Language).
VQL and is the language provided by Virtual DataPort to query views, manage elements in Virtual DataPort (data sources, views, web services, etc.) and perform programmatically almost any of the tasks that you can perform from the administration tool.
VQL is highly compatible with SQL.
Data Catalog¶
The Data Catalog Guide explains how to set-up Data Catalog and use it.
Diagnostic & Monitoring Tool¶
The Diagnostic & Monitoring Tool Guide explains how to use the Diagnostic & Monitoring Tool to:
Display the real time status of one or more Virtual DataPort servers
Diagnose past issues by processing the log files generated by Virtual DataPort.
Scheduler¶
The Scheduler Administration Guide explains how to use the Denodo Scheduler.
Solution Manager¶
The documentation of the Solution Manager is divided in two documents:
Solution Manager Administration Guide
Explains how to manage clusters of Denodo servers using this tool.
