The posts PostgreSQL: Partitioning big tables Part 1 and Part 2 describe the implementation of this performance measure from the database view. In an enterprise Java environment often a database is integrated by a JPA framework and closely coupled with the application. This 3rd part about partitioned tables in PostgreSQL shows additions necessary when using Hibernate.
This is the first post in a new series about our open source framework Hibersap. You can use Hibersap in your Java applications to implement interfaces to SAP systems. Under the hood, Hibersap uses the SAP Java Connector version 3 or a JCA compatible resource adapter to connect to SAP. It makes use of Java annotations to map Java classes and fields to ABAP function modules and their parameters and offers a Hibernate-like API to remotely execute those function modules.
In this post we will develop a small sample application that shows Hibersap’s basic concepts. The following posts in this series will successively demonstrate other concepts like transactions, data type conversion, using resource adapters or testing Hibersap applications.
