The goal is to be able to extract the necessary information, preferably with one query, from the data sources. Click here for the MySQL DDL for this example. The primary key fields are underlined, and there is a foreign key from orderitem.orderId to order.orderId. Orderitem( orderId, productId, quantity, itemCost) The other database, called orders, contains order information: orderinfo( orderId, orderDate, custId, totalAmount) One database, called customers, consists of customer information and has one table: customer( custId, custName, address) We will use a simple example that consists of two databases. UnityJDBC provides quick and easy multi-source SQL querying including MongoDB, Splunk, MySQL, and all relational databases. This article covers the various options for querying and reporting data from multiple sources and different techniques and software that is available. The challenge is how to manage and use this data with minimal investment in time and cost. These data sources may be physically distributed, in virtualization and cloud environments, and be hosted on software of various operating systems and database vendors. This often happens as companies add new systems to their organization via growth in new business, mergers and acquisitions, or replacing and upgrading existing systems. It is very common that the data needed for a report, business decision, or application is spread across several data sources which may be relational databases, spreadsheets, documents, NoSQL sources, or "Big Data" sources.
