As we established in Chapter 4, a service-oriented architecture represents a technical view of a business automation solution based on service-orientation principles. Because much of the discussion in this chapter is focused on business analysis in preparation for the service modeling process, we frequently use the broader term service-oriented environment to refer to the logical enterprise domain in which service-oriented principles are being applied. For the purposes of this chapter, therefore, a service-oriented environment can encompass business processes as well as the technology that automates them.
Another term commonly used instead of service-oriented environment is the SOA ecosystem.
How case studies are used: Most of the examples in this chapter center around the RailCo environment as it prepares to proceed with a service-oriented analysis. (It is recommended that you read through these examples prior to commencing with the service modeling process in Chapter 12.)
The TLS SOA also is reviewed to highlight examples of existing entity-centric services. The last example states TLS's intention also to undergo a service-oriented analysis as the first step of a project required to deliver a new Timesheet Submission solution. This analysis phase is explored in detail at the end of Chapter 12.
