Introducing the JDBC/ODBC eWay
Welcome to the Sun SeeBeyond eWay™ JDBC/ODBC Adapter User’s Guide. This document 
includes information about installing, configuring, and using the Sun Java Composite 
Application Platform Suite JDBC/ODBC eWay™ Adapter, referred to as the JDBC 
eWay throughout this guide. 
This chapter provides an overview of database connectivity (JDBC) and open database 
connectivity (ODBC) APIs. This chapter also introduces the JDBC/ODBC eWay.

About Java Database Connectivity (JDBC)
Java Database Connectivity (JDBC) is an implementation of the Java programming 
language that dictates how databases communicate with each other. Through a 
standardized application programming interface (API), connectivity from database 
management systems (DBMS) to a wide range of SQL databases is accomplished. By 
deploying database drivers laced with JDBC technology, it is possible to connect to any 
database -- even in a heterogeneous environment -- and access tables, tabular data, flat 
files and more. When using JDBC, Java programmers have the ability to request 
connections to a database, send queries to the database using SQL statements, and 
receive results for advanced processing.
1.1.1
JDBC Drivers
To connect with individual databases, JDBC requires drivers for each database. Those 
drivers come in four varieties. Driver types 1 and 2 are typically intended for 
programmers that write applications. Driver types 3 and 4 are typically used by
