Overview
This seminar will utilize an interactive lecture and case study scenarios to illustrate the concepts of SOA systems, development of Service-Oriented applications, how SOMA design techniques are implemented and the integration of enterprise components. Additionally, we illustrate the differences techniques used vs. OOAD processes, SOA requirements gathering, identifying services and processes, development of process modeling using BPM and BPEL, depict the four stages of SOAD, depict the SOA patterns, depict integration of BPM and Use Cases, identify services, define service implementation, service design, locate Classes and relationships from Use Cases, integrating UML class notation, usage of interface and data mapping, illustrate BPEL modeling concepts (Partners, variables, scope, etc), integrate advanced BPEL concepts, use of integration patterns. This course utilizes intricate sets of various case studies to demonstrate the capabilities of design diagrams and various testing strategies.
All aspects of this class will illustrate the architecture and design of an efficient and effective SOA environment.
Prerequisites
Each student should have a basic understanding of application development either as a developer, project manager or end client.
Class Format
