Denodo Express connects and integrates structured, unstructured, and important data sources on-premises and in the cloud. Users can access these resources, together with enterprise apps, dashboards, portals, Intranets, search, and other tools.

What is Denodo Data Virtualization?

Denodo Data Virtualization is the fastest way to access all your enterprise data without having to be concerned about the underlying complexity.

Data virtualization is a logical data layer that integrates all enterprise data from multiple systems, controls the unified data for centralized security and governance, and makes it available in real-time to business users.

How Does Data Virtualization Work?

Data virtualization is a logical data layer that unifies company data from several systems, regulates it for centralized security and governance, and distributes it in real-time to business users. Data virtualization uses a three-step process connect, combine, and consume to get a holistic view of the enterprise data across all of the underlying systems.

How Data Virtualization Work

1. Connect to Any Data Source

The Connect layer allows the upper layers to access data from multiple repositories while insulating them out from the complexities of the core communication protocols and formats.

Data virtualization connects to a variety of structured and unstructured data sources, including databases, big data systems, streaming sources, cloud repositories, the Web, NoSQL sources, and flat files. It employs customized connectors to connect particular data repositories or applications, and it converts and normalizes data source types such that all base views seem as relational views to the higher layers.

2. Combine Any Type of Data

The Combine layer uses a library of pre-built templates and components to dynamically automate Web integration processes by modeling workflow, navigation, and extraction, as well as the structuring of Web, semi-structured, and unstructured data.

It allows for the building of composite data views on top of the connecting layer's base perspectives using logical operators for data transformations. In this layer, users can do complex data transformations, metadata modeling, data quality, and semantic matching operations using SQL and relational tools they're already familiar with.

3. Consume the Data in Any Mode

The Consume layer provides a single point of access to the underlying data sources, as well as abstracted data views in a uniform delivery style.

JDBC, ODBC, ADO.NET, SOAP web services, RESTful web services (output as XML, JSON, HTML, or RSS), OData, portlets, and data widgets (JSR-168, JSR-286, or Microsoft Web Parts to be implemented in SharePoint), exports to Microsoft Excel/SQL, and JMS message queues are all available at the Consume layer.

Why Denodo tool?

The Denodo Platform achieves breakthrough performance in big data, logical data warehouses, and operational situations; it accelerates adoption with cloud data virtualization, and it streamlines data used by business users with self-service data discovery and search. The Denodo Platform employs the most advanced big data optimization algorithms. Some benefits of using the Denedo tool are as follows:

1. Breakthrough Performance in Big Data, Logical Data Warehouse, and Operational Scenarios:

  • The Denodo Platform utilizes the most cutting-edge big data optimization approaches. The Dynamic Query Optimizer applies the "move processing to the data" approach automatically to reduce network traffic.
  • The optimizer chooses the best query execution plan based on data source statistics and indexes, as well as the unique characteristics of huge data sources, to give the greatest performance.
  • When deployed as a logical data warehouse, The Denodo Platform 6.0 produced benchmark results comparable to a physical data warehouse, but at a lower cost and faster time-to-value. 
  • The Denodo Platform includes a powerful caching mechanism that permits full-view materialization as well as query-by-query caching, in addition to the Dynamic Query Optimizer.

2. Expeditious use of Data by Business Users with Self-Service Discovery and Search:

  • For searching actual data, the Denodo Platform provides a user-friendly interface. Users can also browse defined associations between data items to search for specific data.
  • Users can "walk" the canonical data model to learn what data is accessible, its structure, relationships to other data entities, and any other information supplied by the data architects, such as documentation and usage notes, allowing them to search, browse, and query in a fairly easy manner. 
  • Users may now create ad-hoc queries and save them as views using the new Advanced Query Wizard.

3. Broad Connectivity to the Widest Range of Data Sources:

  • Any data source, in any format, in any place, including Web, semi-structured, and unstructured data, can be connected to the Denodo Platform. 
  • The Denodo Platform can handle relational databases, multidimensional databases, Hadoop, NoSQL (document, graph, key-value, triple, columnar), streaming data, flat files (Excel, XML, Delimited, Log), REST and SOAP/WSDL web services, web, documents (Word, PDF), email, and more.
  • For data sources that the Denodo Platform does not support, a connector SDK and an Eclipse plugin are provided.
  • The Denodo Platform now supports and connects to the widest range of big data sources, including Redshift, HP Vertica, Impala, and Apache Spark, in addition to its previous support for Teradata, Netezza, Hive, Impala, and Greenplum.

4. Support for a Wide Range of Operational, Analytical, and Big Data Use Cases:

  • The Denodo Platform offers a wide range of use cases in addition to the traditional analytical use cases offered by most other data virtualization platforms. 
  • Big data, operational, Web integration, and traditional data management use cases are all supported by the Denodo Platform. Learn more about each scenario by clicking on the links below.
  • You may also develop a data services layer with the Denodo Platform, which exposes the underlying data sources as services.
  • For integration with enterprise portals and Microsoft SharePoint, the data services can be published as SOAP/XML or REST web services, as well as portlets and web components.
  • Data services allow the virtual view developed within the Denodo Platform to be reused and give a single, consistent representation of the underlying data assets.

5. Controlled Access to Information, with Advanced Security:

  • Controlled access to role-based security access, schema-wide and data-specific permissions, and significant support for major security protocols, including Kerberos single sign-on, are among the policy-driven, row-based, and column-based security management capabilities.

6. Accelerated Adoption with Data Virtualization in the Cloud:

  • Denodo Platform 6.0 will be the first and only data virtualization solution available on Amazon AWS Marketplace. 
  • It lowers the cost of data virtualization, simplifies its use, and accelerates its adoption. Nothing has to be set up or installed. 
  • The Denodo Platform for AWS has a scalable architecture that allows customers to quickly deploy instances.

Denodo Testing Tool

The Denodo Testing Tool enables users to simply automate the testing of their data virtualization scenarios, both during the development and maintenance of their virtualized solutions, acting as a safety net before making any significant modifications to these environments. 

The Denodo Testing Tool is a small standalone application with a straightforward user interface that can be run from the command line. Look at the following information of the Denodo testing tool:

  • Text files and folders are used to specify and organize tests. There's no need to learn Java.
  • The execution of test sets is totally automated. Executions of test sets can be incorporated into current continuous integration (CI) workflows.
  • Test inheritance is provided for the more accessible design of huge collections of closely-related tests.
  • System for reporting test results that is pluggable.

Limitations of Denodo

There are a few disadvantages to using the Denedo tool, which are listed below.

  • Because Denodo still has a limited community of super users, there isn't much documentation available in case you get lost.
  • Because data virtualization isn't cheap, smaller businesses may be hesitant to use it because of the expensive licensing fees.
  • Because not all API queries provided all information, schema creation of endpoints from API responses was occasionally lacking. The possibility to load the schema (XSD/JSON/Soap XML, etc.) would be beneficial.
  • When we used Denodo exposed web services, they were in a beta state
  • While the export/import deployment was beneficial, there were some unanticipated challenges that occurred without any errors. Only during testing were problems discovered. Some views were improperly built and did not function. It should work in the environment where it is imported if it worked in the environment where it was exported from.
