LeanXcale enhances the standard DBA API functionality by seamlessly integrating array support, providing advanced data manipulation capabilities. This powerful feature simplifies data modeling and is particularly useful when dealing with structured data where you have to aggregate in relationship 1:n. By incorporating array columns into your database schema, you can manage all the array complexity by accessing any of the fields of the array individually, retrieving all the array values, or aggregating in relationships 1:n while maintaining compatibility with standard DBA API practices.
