    • WA1571 Service Oriented Architecture for Architects (Oracle Edition) Training and Courseware Service Oriented Architecture (SOA) shows demonstrable signs of simplifying software integration. It can reduce the cost of integration significantly. Organizations are beginning to architect new integration solutions following the SOA approach. This course delves deep into various architectural aspects of SOA. It starts with the Service Oriented Analysis and Design. This will help the architects understand how requirements are captured, business processes are modeled and services are identified. It moves on to data, transaction and messaging architecture. Topics The course covers the following key areas of architecture: 1. Service and business process design. 2. Messaging architecture in SOA 3. Transaction management 4. Best practices What you will learn Students will get to actually apply various principles in hands on exercises. This will make the concepts come alive. After taking the course, an architect will gain enough knowledge to begin devising a comprehensive architecture for a new SOA based solution. Audience IT architects, senior developers. Prerequisites Previous experience with software architecture is recommended. Some knowledge of Object Oriented Analysis and Design is required. Duration Five days.
