Denodo is the product of Denodo Technologies; it is the data virtualization with Graphical User Interface based studio. Denodo is the ruler in data virtualization; it provides the benefits of managing the integrity, availability, usability, and security of the data, easy data access, and data delivery abilities across the enterprise, cloud, unstructured, and big data sources without transferring the data from its native storage. Data virtualization is used for enterprise-level semantic or general data layers, data warehousing projects, large-scale applications, and small initiatives requiring quick data access. The Denodo tool is used in banking, social media, marketing, entertainment, and big data industries.
Denodo platform is the data management platform that provides all the features to build a logical data warehouse. It provides a semantics layer to make data more simplified and available to businesses. The Denodo platform helps in data preparation for self-service analytics, faster insights, privacy, and data management automation. It combines the data into logical/virtual data to provide unified access delivery through a single virtual data layer. We need Denodo to make our work easier as it.
1) Delivers breakthrough performance in big data, logical data warehouse: the dynamic Query Optimizer automatically applies the 'move processing to the Data paradigm' to decrease network traffic. As a logical warehouse, the Denodo platform 6.0 is employed. It can display results comparable to a physical data warehouse and supports full-view materialization.
2) The Denodo platform enables users to search the data using an intuitive interface. It enables users to browse and search to discover the available data, its structure, its relationship to other data entities, and information about the documentation and usage notes.
3) The Denodo platform meets security/privacy requirements like restricting exposure to role-based security access, schema-wide and data-specific permissions, and full backing for major security protocols.
4) The Denodo Platform can connect to any data source, in any format or location, like Web, semi-structured, or unstructured data, and it includes optimized adapters for all major data sources, including relational databases, multidimensional databases, NoSQL, streaming data, flat files, internet services, Web, documents, email, and others.
5) Denodo platform 6.0 will be the first data virtualization technology available on Amazon AWS Marketplace. It provides easy management of data. Denodo platform for AWS offers a scalable infrastructure that users can smoothly add instances.

Data virtualization allows organizations to combine real-time data from multiple sources and make it available without exposing technical details. Denodo is based on the 3C principles.
1) Connect (to disparate data sources):
It connects any data source like APIs, files, and databases. Data remains in the sources and is accessed on demand without creating another copy.
2) Combine (related data into views):
As its motive is to gather data from sources to satisfy business requirements, this layer is used. In this step, a developer is expected to explain the data combination and transformation to suit the enterprise's requirements.
3) Consume (in business applications):
lastly, a method for making real-time data accessible to data consumers. Denodo offers various options for users to access data, containing JDBC drivers, ODBC interface, and web services (REST/SOAP).
Data virtualization builds a single layer to store disparate data with unified access to the applications. In this approach, data management allows applications to use semantic components specified in the virtual layer to retrieve and manipulate data without requiring technical details like (where it is located) and reuse them as required. Denodo platform offers the following features:
In this section, we will discuss the setup of Denodo and start our data Virtualization journey.
Step 1: Install Denodo platform 8.0 in a directory and name it <DENODO_HOME>. – First, download the installer and license from "https://community.denodo.com/express/.
Step 2: Import "MySQL-connector-java-.jar" into the "Virtual DataPort Administration Tool." Upload the jar files of the driver through Admin Tool Wizard "File/Extension Management" and choose "MySQL-5" as the version.
Step 3: Installing and Configuring the Database
Step 4: Install the web server
1) Initial steps
Following are the steps for using the Denodo platform
Combine the customer view you have created with the billing information in this section to create a report showing the total amount due for each client.
Denodo platform is built with a client-server model in which clients send requests. The following interfaces can be used to send requests.
Data through users' virtualization software pulls data from target sources, then combine it in real-time to provide the outcome needed when accessing the performance; it's important to see which element causes a delay in the process.

The data service layer is a layer that can supply data to various users on a wide scale. Data virtualization can quickly develop new data services by using the view in the virtual layer. Some of the problems that these services encounter is:
1) Defining Contracts/Interfaces
An interface is a view in Denodo that describes fields and their data types. You can create the fields and associate the interface data in the top-down design.
2) SOAP Web Services
Web services are those solutions that enable the machine to machine communication via the internet. To exchange messages, these services employ SOAP protocol.
3) REST Web Services
REST services are different Web services. This type of service communicates through HTTP and uses the REST architectural style as the messaging protocol.
4) Publish Web Services
This Web container status window in the Denodo Administration tool is used to manage REST and SOAP services. To get this tool on the screen, go to the Tools >Web services container in the menu bar, and a table will appear, listing the web services generated in a certain Denodo Database.
5) Invocation of Services
REST services work the same as the RESTFUL services; however, you only have access to the views built with the REST services.
6) Change Web Service Implementation
It's used to make a derived view and to implement the i_client_info interface to utilize client_info_impl as its implementation view in this section.
The marketing department compiles a list of new clients daily. An Apache Hadoop distribution is in place to process the input data and produce the needed output to create the list of prospects. This section will teach you how to integrate a Big Data system into the Denodo Platform.
Apache Hive is software for a data warehouse that enables analytics datasets distributed storage easier. HiveQL is a SQL -like language that allows you to project structure onto this data and query it.
Using Denodo Platform 8.0 to access Big Data Platforms is explained in this. Denodo Platform connects to different data sources; the list below is the options used to connect to these systems from Denodo Platform:
HCatalog is a Hadoop table and storage management layer that makes reading and writing easier. It gives a relational view of the data on HDFS with HCatalog, and they don't have to think about where and how the data is stored.

Denodo Agile BI will go through the basics of using Data Virtualisation tools and how Denodo Platform analyses Business data for Operational insights. Key advantages of adopting Data Virtualisation:
Traditional business methods sometimes result in the repetition of logic being built repeatedly on BI and reporting systems to generate similar results. Now the logic for the business required to build all the reports will be collected by the Data Virtualisation layer, making it simplified, modified, and easily shared with external BI tools without duplicating code across them.
Data is stored and organized into a unified manner of marketing promotion performance. The procedure for this is like this:
For real-time retrieval of data, connect Denodo to your Data Sources.
Now, it's time to combine all the data that we have data sources and base views in place. The first step is to make a standardized view of each data source to create a set of foundation business entities for more complex reports to build later.
This BI tool connects to Denodo through ODBC and shares regular SQL queries. Denodo delivers all the views automatically over JDBC and ODBC by default. We need to perform manual publishing procedures when establishing web services.
A client tool is used to access the views we developed in the Denodo Platform. We'll use Tableau. However, any standard tool may access Denodo using the JDBC, ODBC, or Web Services interfaces.
Follow the steps to create a SOAP web service in Denodo:
Step 1: Utilize the Virtual Data Port Administration Tool to create SOAP Data Services by going to the Administration tool to create a new folder in the two data service folders.
Step 2: Right-click on the folder and choose "New/Data Service/SOAP Web Service."
Step 3: This opens the "Create SOAP Web Services" Dialog. This dialog has the following tabs:
Step 4: Press “+ next” for the “i_client_info” and rename operation “getl_CLIENT_INFOByCLIENT_ID.” to: getClientById
Step 5: When you search the clients through ID, you must leave the input_parameter "client_id" and the rest. You can do it through choosing Drop by clicking on other fields.
We are deploying the web services by right-clicking them.
This will deploy the web service and deliver the URL to access the web service.
