  RQAPI can be used to access and manipulate data stored in relational databases. It provides a unified interface for accessing data from multiple sources, including SAP HANA, Oracle, Microsoft SQL Server, and IBM DB2. To use RQAPI, users must first create an RQAPI connection object that contains the necessary information about the database they want to access. Once the connection object is created, users can then execute SQL queries using the RQAPI APIs. 
  
  Tips & Tricks: 
  When using RQAPI, it is important to ensure that the connection object is properly configured before executing any queries. Additionally, it is important to ensure that the SQL query is properly formatted before executing it. This will help ensure that the query runs efficiently and returns accurate results.
