Chapter 1. Overview of the data virtualization tutorial
This tutorial demonstrates how to use Red Hat Integration data virtualization to create a customer portfolio virtual database. The virtual database that you create integrates data from the following two sources:
- A postgreSQL accounts database
- Stores customer account information, and data about the stock holdings for each customer.
- A web-based REST service
- Provides live stock market price data.
By integrating data from these two sources, the Portfolio database calculates the value of individual customer portfolios based on current stock prices. After we deploy the virtual database, we’ll submit queries to it to demonstrate how data from both of sources is combined.
