Introduction The rules as followed by the SOA are the most appropriate ways to imply in the functioning of Service-Oriented Development of Badger Brick. These rules are reusable, has got granularity, modularity and the capacitance of composability. These are also the spaces for componentization, and interoperability. In addition to all these, there has to be the compliance to standards in both the cases of common and industry-specific categories. Thus to choose this process by Badger Bricks comes closer to the appropriateness of services as delivered. The identification of services and categorization, provisioning and delivery, and monitoring and tracking are the added beneficiary factors.

This paper concentrates on the following of the specific architectural principles for design and service definition focus on specific themes that influence the intrinsic behaviour of a system and the style of its design; Service encapsulation, Service loose coupling, Service contract, Service abstraction, Service abstraction, Service reusability, Service composability, Service autonomy, Service optimization and Service discoverability. The route cause of discussion of this paper is the modelling as adopted by BPMN. The modeling in BPMN is of a small set of graphical elements.

The purpose of it is to make the flow and the process of understanding for business users and developers much easier and comprehensible. There are four basic categories of elements, applicable in the process of understanding. These are flow objects that comprises of events, activities and gateways. The next is of connecting objects, by means of sequence flow, message flow and association. Swimlanes are the next in preference which works through pool and lane. Lastly there is the need of artifacts that has got data objects, group and annotation.

Requirements Specification Badger Bricks is planning to have SOA in its functionalities. As such there are certain basic things that it has to meet to have proper assessments. There is the need of interoperability between different systems and programming languages. OASIS defines SOA as, A paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains. It provides a uniform means to offer, discover, interact with and use capabilities to produce desired effects consistent with measurable preconditions and expectations. SOA Meta Model, The Linthicum Group, 2007 Sources - http: //en. wikipedia. org/wiki/Service-oriented_architectureThis provides the basis for integration between applications on different platforms through the communication protocol.

The concept of messages is one such for instance. The use of messages across defined message channels decreases the complexity of the end application. It is here that it allows the developer of the application that is Badger Bricks will have the focus on the true application of functionality instead of the intricate needs a communication protocol. The second most important requirement is the desire to create a federation of resources.

It needs the establishment and maintenance of data flow to a federated data warehouse. This is the way that allows new functionality developed to reference a common business format for each data element. Badger Bricks must have prolific command over both the requirements to access through SOA that is the Service –Oriented Architecture.
