A longer term goal of Service-Oriented Integration (SOI) is to enable composite applications that
are assembled from SOA Services. Which statement best describes the relationship between
composite application assembly and SOA Service engineering?
A.
Composite application assembly and SOA Service engineering are separate, decoupled efforts
without any meaningful Interaction.
B.
All SOA Service engineering must be completed prior to any composite application assembly.
C.
Composite application assembly uses service contracts created by SOA Service engineering
and generates requirements that are Inputs to SOA Service engineering.
D.
SOA Service engineering creates SOA Services following sound engineering principles, while
composite application assembly uses SOA Services based on WSPL interfaces.
Explanation:
The Oracle Service Engineering Framework is an engineering approach for delivering
projects within an SOA environment
The Service Engineering Framework addresses activities at both the program and
project scope to consider the requirements of the business outside of the scope of a
single project.
Topics covered at the program scope include:* SOA Requirements Management – Provides a process for harvesting
requirements in a manner that naturally facilitates service identification and
discovery.
* Service Identification & Discovery – Establishes the procedures around
identifying Service candidates, as well as discovering reuse candidates from the
existing Service catalog. Takes the process from identification and discovery,
through the justification processes required to determine if an existing Service can
be viable for reuse in the proposed manner, or if the proposed Service Candidate
should be realized as a shared Service.
* Service Release Planning – Provides the groundwork necessary for planning for
project and Service deliveries within an SOA
Topics covered at the project scope include:
* Service Definition -* Service Design -* Service Implementation – Provides the guidelines for effectively and efficiently
developing shared Services.
* Service Testing -* Service Deployment – Defines the guidelines and practices that need to be
considered when deploying Services into a shared environment.
* Service OA&M -Note:
The primary goal of service-oriented integration is to better leverage existing systemwithin the IT
environment by applying service-oriented principles. Ultimately, the
goal is to enable the assembly of composite applications, with little or no custom
coding, that include capabilities sourced from existing systems. Composite
applications are applications that pull together data, functionality, and process from
multiple existing sources to solve a business problem or create new business value.
Service-oriented integration is the mechanism to expose existing sources of data,
functionality, and process so that those sources can be readily consumed by a
composite application
