25 Mar 2008 Native XML databases have grown in popularity along with XML, because
data is stored as native XML, rather than through tables in a traditional database.
Using a native XML database means that a change to the schema requires minimal changes
to your code and no change to the database. PHP and Java™ developers can benefit greatly from using native XML databases. In this tutorial, you will get quickly up to speed using a native XML database and see how to use it to benefit XML development.
In this tutorial
This tutorial shows you how to reduce development time with a native XML database. As
an illustration, you will change an existing XML schema, and see these changes in the
code also. Developers will learn the common necessities for working with a native XML
database in both PHP and Java technologies. To learn and implement the tutorial objectives, you'll create several Web applications where
users can enter and view patient data in PHP code, and then enter and view doctor data
in Java code.
Objectives - Connect to the database (DB2 Express-C 9.5).
- Store and retrieve XML data.
- Create a form that writes new data to the database.
- Create a form that reads existing data from the database.
- Query the database using SQL/XML.
- Enhance the data viewers to support a quick search function.
- Modify the database schema.
Prerequisites
This tutorial is recommended for Java and PHP developers who use XML and want to
explore the benefits of native XML databases (IBM® DB2® Express-C 9.5 in
this tutorial). Although it is helpful to have some knowledge of PHP and Java
programming, it isn't necessary to follow along and learn from this tutorial. Knowledge
of the XML DOM is also helpful.
System requirements
You will need JavaScript enabled in your browser. Beyond a text editor and a browser, you'll need the tools necessary to support Java and PHP servers:
-
Java JDK, the latest JDK
from Sun to run and compile Java code. This tutorial uses version Java 6 update 5.
-
Apache Tomcat, the Web server that will host your Java applications. This tutorial uses version 6.0.16.
-
PHP, the latest version of PHP, 5.2.5 at the time of this writing.
-
Apache2, the Apache2 HTTP server that is the recommended HTTP server for PHP.
- Operating System, any will do. This tutorial was written on a machine running
Windows Vista® Ultimate.
-
DB2 Express-C 9.5, the
database used for this tutorial. You can use any native XML database such as Apache Xindice instead.
You can get all the source code from Downloads in the tutorial.
