Using standard library routines, you open a connection to the database.

You then use JDBC to send your SQL code to the database, and process the results that are returned. Such an approach has to be contrasted with the precompilation route taken with Embedded SQL.

This document illustrates the basics of the JDBC (Java Database Connectivity) API (Application Program Interface).

Here, you will learn to use the basic JDBC API to create tables, insert values, query tables, retrieve results, update tables, create prepared statements, perform transactions and catch exceptions and errors.

Here is what you can find in this article: The sole purpose of this article is to serve as an introductory reading for those who have never used the two together.

Therefore, some knowledge of both Oracle and Perl is assumed, and although I will not try to show off my obfuscation abilities, this article still assumes that the reader has read "Learning Perl" and has some experience with Oracle RDBMS.

One of us (Seltzer) has spent her career between the worlds of filesystems and database management systems.

If questioned, she'll argue the two are fundamentally the same thing, and furthermore, operating systems and database management systems are essentially both resource managers and providers of convenient abstractions.

The differences are "merely" implementation details. The other (Bostic) believes in the tool-based approach to software engineering and in the construction of components based on simpler building blocks, because such systems are invariably superior to monolithic architectures in the important "-bilities": understandability, extensibility, maintainability, testability, and flexibility.

When you combine those two perspectives, it's not surprising to learn that together we spent much of the last two decades working on Berkeley DB—a software library that provides fast, flexible, reliable and scalable data management.

Here is an easy way of visualizing what happens in a call level interface: You are writing a normal Java program.

Somewhere in the program, you need to interact with a database.

However, it provides those features in a library that links directly with the application that needs those services, rather than being made available by a standalone server application.
