Hibernate Bulk Amount Data Processing

We are about starting a financial project which required heavily on data processing (like everyday run program to sorting, routing, filtering bulk amount of data).
My question is, Using Hibernate as JPA provider, Where it should be best to handle processing data ? Business Object or in Database batch.
More details:
1. Business Object handle most of processing logic then only trigger CRUD to Database
2. Database handle most of processing logic and CRUD to database table, Business Object handle
Which one is better approach in term of maintainability and scalability ?
