Introduction to BPEL Process Modeling

Overview

This course will provide each participant with a thorough understanding of the role of Business Process Execution Language and its role for modeling corporate workflows and SOA processing. This course will focus on the usage of business process models, the role of BPEL and BPEL4WS, WBI product support, integration of WSDL and other XML standards, BPELWS partner concepts, stateful interactions, BPEL IBM extensions, use of the WBI Modeler, mapping elements in BPEL4WS, migration of MQ Workflows to BPEL4WS, use of FDL2BPEL migration tool and mapping FDL constructs to BPEL4WS.

All aspects of this class will incorporate the specific architecture of BNSF to illustrate the implementation of these techniques.

Prerequisites

Each student should have a basic understanding of application development and design methodologies.

Class Format

Lecture and Lab

Audience

Designed for programmers, managers, project leaders, enterprise architects and other technical individuals that need to understand the modeling of business workflows.

Learning Objectives

After completing this course, the student should be able to:

Understand the role of business process modeling

Learn the syntax and semantics of BPEL and BPEL4WS

Understand the relationship between BPEL and other Web services standards such as WSDL (Web services Description Language)

Gain experience using BPEL by building a progressively complex, process-centric application

Understand which BPEL constructs are most appropriate for different application scenarios

Using modeling tools to develop BPEL and BPEL4WS processes

Depict the key concepts of BPEL4WS: partners, endpoints, activities, correlation, data handling and scope

Illustrate element BPEL4WS mapping for files, I/O, control nodes, processes, decisions and while loops

Understand the generated files and the role of the different files generated from our BPEL models

Depict the migration of MQ Workflow to BPEL4WS and the use of migration tools
