Database access is the heart of iSeries web applications. There are
two main techniques available: JDBC and Record Level Access (RLA). RLA
is similar to using file I/O operations in RPG, while JDBC uses SQL.
Which should you use for any given job? Whether you're creating web
applications, client programs, or server-side code, you need to know
how to effectively use JDBC or RLA to access your iSeries data.
In this new, fast-paced 20-hour training course, Joe Pluta takes you
step-by-step through many labs which allow you to compare and contrast
both JDBC and RLA. Using short, easy to understand labs, you'll create
Java classes to read files sequentially and by key. You'll learn how
to create complete CRUD classes (Create, Read, Update, Delete) using
both RLA and JDBC.
Topics covered in this hands-on course include:
Sequential access with RLA and JDBC
Creating and closing connections
Working with records and fields from database files
Using RLA and JDBC for keyed access
Updating records using RLA and JDBC
Error handling using the database access techniques
Inserting new records with RLA and JDBC
Creating a 3-tier client application to display, insert,
update and delete data
Using an Abstract Class to simplify Java development
The JBUI classes to provide powerful user interfaces, far
simpler than AWT or Swing
Note: This course uses VisualAge for Java version
3.5 or 4.0, provided with the IBM WebSphere Development Tools for iSeries.
The course is an ideal follow-on to Practical
Java Programming for WebSphere. Some experience with Java
is assumed. When should you use JDBC? When should you use RLA? With
this training youll always make the right choice to maximize Java
Database performance and make your job easier.
