How to dump multiple db tables into EL?

How to dump multiple db tables into EL? Can you shed a me light?

It's not possible to provide a good answer without additional details. Are the tables related, i.e. would you join them in the relational database? If so, is a one-to-one, one-to-many, or many-to-many relationship?

yes, trying to load all tables from one RDBMS database to EL, just like we use sqoop in hadoop.

Please answer all my questions.
