Standards-based service contracts can map the relevant XML schema constructs to and from Java. For both SOAP and REST services, the JAXB 2.0 standard offers support for the entire set of XML schema features. Industry standards are widely used in service contracts and do not introduce particular challenges when using Java.

The SOA architectural style is fundamentally about separation; establishing smaller, separate units of capability that create a more agile application and infrastructure environment. Most of the core SOA principles such as loose coupling, abstraction, virtualization etc depend upon the existence of a contract. The concept of service contract appears in various guises at different points… Guiding Principles of SOA: Standardized service contract: Specified through one or more service description documents. Loose coupling: Services are designed as self-contained components, maintain relationships that minimize dependencies on other services. Abstraction: A service is completely defined by service contracts and description documents. They hide their logic, which is encapsulated within their implementation. The SOA Principles state that the Standardized Service Contract design principle is perhaps the most fundamental of the eight service-oriented design principles. It is by means of service contracts that services express their purpose and capabilities (Ref1. SOA Principles Website).

Rather, a service contract outlines a set of technical data, and often business information as well. The contract is between whoever is providing the Web service, and whoever is consuming the Web service. It provides details about the service being created by the provider.

The Service Contract: The Most Important Metadata for SOA The most basic interaction in SOA is between Service providers and Service consumers. For each interaction between these two parties, one provides some combination of data and functionality and the other consumes it. Service-oriented Architecture (SOA) is as simple as can be. There are 9 design principles to keep in mind when designing a SOA service: 1. Standardized Service Contract. Services adhere to a service-description. 2. Loose Coupling. Services minimize dependencies on each other.

The standardized service contract is a software design principle applied within the service-orientation design paradigm to guarantee that service contracts within a service inventory adhere to the same set of design standards. This facilitates standardized service contracts across the service inventory.

SOA Principles of Service Design by Thomas Erl – Chapter 6: Service Contracts ( Standardization and Design) is dedicated to exploring this design principle in 29 Jul 2014 Some SOA projects will employ both a bottom-up and a top-down approach to identify and design services and service contracts, which often 15 May 2015 Most of the core SOA principles such as loose coupling, abstraction, virtualization etc depend upon the existence of a contract. The concept of 20 Oct 2007 Standardized service contracts are one of the key Service Oriented web services have evolved as the most common SOA implementation. Service-Oriented Architecture (SOA) has finally turned a corner: companies are to define a contract that stipulates IT “rules of engagement” in a standardized
