Course Overview Modern Service-Oriented Architecture (SOA) is enabling software technology to move beyond discrete, disparate programs and combine these programs into interoperable applications that map directly to business processes. SOA creates agility while reducing cost and delivery time. In this course, you gain a foundation in the concepts, modelling, design and implementation of SOA. You gain the knowledge to strategically develop SOA methodologies, technologies, languages and tools. Audience This course is valuable for analysts, strategists, software architects and anyone seeking a technical understanding of SOA. Programming experience is helpful, but not required.
