Microsoft Power BI is one of the leading tools for analyzing data and generating insights. Power BI is a unified, scalable platform for self-service and enterprise-level business intelligence (BI) tools which helps in connecting to and visualizing any type of data and generating insights from it which help in making better business decisions. With Power BI, amazing data experiences can be created; sharing and collaborating data across other Microsoft tools become easy. Power BI also has AI capabilities which help to get answers to business questions in a conversational manner. This powerful reporting tool has 150+ connectors. One of the popular data connectors is the Oracle database which is a Java-based object that implements the javax. SQL. The Oracle database is one of the world’s leading converged, multi-model database management system (DBMS) and has in-memory, NoSQL, and MySQL databases. Oracle database products reduce operational costs by up to 90%, protect against data breaches and provide high-performance versions of the Oracle database to its customers.
