1. WTX Overview

2. Agenda Goal today is to provide the very basics
The fundamentals course for WTX is a 5 day class
Overview
WTX Tools, Components, Development Environment.
Demo building a WTX interface start to finish.

3. IBM WebSphere Transformation Extender
What is WTX?
IBM WebSphere Transformation Extender

4. WTX is… A fully mature tool An any-to-any mapper
It’s been around since 1992.
IBM bought in 2006 and version 8.2 was the first in Eclipse.
An any-to-any mapper
Multiple inputs and outputs in any format
Flat files, XML, Database, X12, SWIFT
Adapters:
File, Database, MQ, HTTP, FTP, SOAP, Shell/Batch
Very good at:
Parsing and validating flat files
Complex transformations

5. What Sets WTX Apart? It’s Fast.
Very Fast Development
Full library available on your desktop for fast and easy testing
No deployment to a server necessary to unit test code
Very Fast Runtime Execution
Compiled C
Parse and validate 500 meg flat files in seconds

6. WTX Components Type Tree Designer Map Designer Other Tools
Trees are similar to XML schemas
They represent the structure of the input and output data
Just like XML you have simple and complex objects to build representations of your data
Simple Objects are called Items
Complex Objects are called Groups
Map Designer
Defines Transformations and Business Rules
Other Tools
Database Interface Designer
Importers
Resource Registry

7. WTX Development Methodology

8. WTX in Four Steps Develop Trees Develop Maps Deploy to Runtime
Create or import Input Trees to parse and validate data
Create or import Output Trees to build your output structure
Develop Maps
Functional Maps (Looping), Drag and Drop Groups and Items
Unit test locally on your desktop
Deploy to Runtime
Deploy compiled maps to be executed by WESB
Troubleshooting
Trace, Audit logs, Debugger, Profiler
DEMO

9. WTX Importers Importing Trees
Provides automated creation of Type Trees saving you hours of development work
Formats Include:
XSD (XML)
Fixed length Flat Files (copybook)
WSDL
Type Tree Maker (advanced)

12. WebSphere Integration Developer
WTX Perspective
Design Studio
Has it’s own version of Eclipse
WebSphere Integration Developer
We can use this version of Eclipse to develop WESB flows and open maps/trees using the WTX perspective

13. WTX at Runtime Execution
WTX Runtime Mapping Steps
Read all input cards sequentially into memory
Read Input card 1, 2, 3, etc.
All Inputs are available for use in any output
Executes output cards sequentially
Output card 1 completes, 2 completes, etc.
Output card 3 card may use data from output card 1 & 2
