Web Services: The Tools, Technologies and Standards

1 Day Seminar

Endorsed by

UK Chapter

Speaker:

Rick van der Lans

Currently, the magical word is web service. It is a new set of standards and technologies for integration internal applications and for enterprise integration.

Everyone is talking about the three standards: SOAP, UDDI and WSDL. Standards are important, but how mature is the technology and what can we do with it today? This seminar presents an overview of the state of the art. What is the status of each standard, and more important, how is the level of support by the tools and the technology? Is it already possible to develop mission critical application with web service technology? Should we start adopting this technology now, or should we wait?

The topics covered in this seminar are grouped in three areas. First of all, an overview is given of the following web service related standards and how they interrelate:

SOAP, UDDI and WSDL
The IBM/Microsoft stack: WS-Inspection, WS-Reliability, WS-Security, and WS-Transaction
BTP (Business Transaction Protocol)
WSCM (Web Service Component Model)
BPEL4WS (Business Process Execution Language for Web Services), and BPML (Business Process Modelling Language)

Secondly, an overview of the tool market is given. Many different types of tools support web services today. There are tools to create web services, middleware tools to send SOAP messages, such as Bea Systems, CapeClear, Grand Central and Iona. And vendors of EAI tools (Enterprise Application Integration) are now implementing web services. A new promising category is appearing on the market aimed at managing web services. Vendors such as AmberPoint, Grand Central, and TalkingBlocks focus on this area. For the link with business process management we are getting tools from Avinon and Savvion.

Thirdly, the seminar will discuss designing and using web services. Design rules are given for defining the ideal interface for a web service. For example, the differences are given between using the inside-out or outside-in approach. Classic terminology, such as coupling and cohesion, is brought back to life.

In a nutshell, this seminar presents a complete and realistic picture of where we stand today with respect to web service standards, tools, technology and practices. It focuses on using web services for application integration and enterprise integration.

This seminar is aimed at participants who are interested in using web services for integration.. The seminar is designed for IT-managers, technology planners, architects, consultants, system analysts and designers, database designers and database administrators.

All participants will receive a copy of the slides used by the presenter, plus a 300-page booklet that contains many articles concerning web services and related topics.

1. Introduction web services

From components to web services
XML as a format for data exchange
The added value of XML frameworks, such as BizTalk, ebXML and RossettaNet

2. Calling web services

Data exchange with SOAP
Why are existing standards for transaction control, such as XA and DTP, not good enough?
The new standard for web service transactions: BTP
What are compensating transactions, atoms and coheions?

3. Discovering web services

The directory for web services: UDDI
The ebXML directory service
Documenting web services using WSDL
WSIL as an alternative to UDDI
