SOA Tutorial. SOA_fundamentals_for_developers. Service-oriented architecture (SOA) | Tridens. Globalization, increased competitive threats, new regulatory measures, rising costs, volatile market conditions – how can today’s enterprises meet these challenges? In order to efficiently cope with increasing business pressures, your company needs to transform itself into a more supple, agile, and responsive enterprise. However, with past fixes having been hastily applied to mission-critical systems, the result instead is all too often a fixed and inflexible information technology (IT) architecture. A service-oriented architecture (SOA) solution concentrates and modernizes your IT structures while, at the same time, addressing legacy system and application issues – with minimal or no disturbance to your business. The advantages of this approach are as follows: SOA is more than an IT solution; it is a paradigm shift, taking the focus off IT and putting it back where it belongs – on customers, service quality, and fundamental business objectives.

David Sprott and Lawrence Wilkes CBDI Forum January 2004 Summary: Gives a concise explanation of service-oriented architecture, what it is, and how it affects what architects, CIOs, project managers, business analysts, and lead developers do.

Over time, the level of abstraction at which functionality is specified, published and or consumed has gradually become higher and higher.
Like objects and components, services represent natural building blocks that allow us to organize capabilities in ways that are familiar to us. For many organizations, the logical starting place for investigating service-oriented architecture is the consideration of Web services. Principles and Definitions Service A Service Definition. Soa-technicalvision-nagappan. The power behind the SOA repository. The basic tenet of a service-oriented architecture (SOA) is to provide loose-coupling for different applications. It is thus imperative that data is produced by and for these applications, and that this data is stored and handled optimally. Given the pervasive nature of each application in an SOA, the way this data is stored is typically location-dependent and specific to the application. An SOA repository is a mechanism that handles the persistence of distributed SOA data. It is a complex and sophisticated enterprise-grade technology that not only handles persistence and caching, but also enables lifecycle management, security, discovery, and transformation of distributed data from diverse service-oriented applications such as silo applications, Web portals, business processes, and mobile applications.
SOA data is basically transient and streaming in nature. SOA data is typically stored in relational databases and filesystems, but these are not entirely capable of handling SOA data. Build03.
