Welcome to these Basic Tutorials about the Denodo Platform. Here you will find a complete set of lessons that describe briefly the main topics you need to know when you start your Data Virtualization project.
All new technologies require some kind of coaching before starting to use them at your own. To demonstrate the features of the Denodo Data Virtualization software we are going to play with several sample data sources included in the Tutorial files (you can adapt them to your specific needs if you want).
Before starting your project, first, you have to stop and understand the problem. Let's suppose we are facing the following scenario:
We said in the previous paragraph: "End users do not want to use different applications to get all the information of customers", so the problem here is to connect disparate data to create a single view of the customer. And that single view has to be reusable (it is an IT requisite).
If you follow a bad design, not reusing components, creating ad-hod code/applications... surely your systems will grow as in the image below:
The main idea is to have a single virtual layer to connect disparate data and to provide unified access to consuming applications. These applications will use the semantic components defined in the virtual layer reusing them when needed. This way your applications will be independent from the physical sources where the data is stored.
At the end of the Tutorial you will notice that:
Before starting the Tutorial, be sure you have all the necessary materials. Check the Installation & Bootstrapping section.
If you already have installed all the components, please, go ahead to the First Steps section.
