Service-Oriented Modeling and Architecture (SOMA)

Service-oriented modeling and architecture (SOMA) is a methodology for modeling service-oriented architecture (SOA) applications. SOMA is an end-to-end analysis and design method that extends traditional object-oriented and component-based analysis and design methods.

SOMA is based on three major phases:

• Identification
• Specification
• Realization

The phases are used to model the three main elements of SOA, which are:

• Services
• Components that realize the services, which are also known as service components
• Flows that can be used to compose services needed in an SOA application

SOMA validates every step of the design phase, ensuring a fully integrated, flexible and responsive SOA business infrastructure.

SOMA is based on several years of hands-on experience that IBM developed in working with enterprises that were early adopters of SOA. SOMA is a flexible approach to solving enterprise issues that provides maximum return on investment. SOMA helps companies implement SOA to have better visibility into their business processes, giving them the tools they need to improve and grow.
