 # Result Set
 
+A result set is a set of results returned after the relational database (RDB) query APIs are called. You can use the **resultset** APIs to obtain required data.
+
 > **NOTE**<br/>
+> 
 > The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.
