Which statement best describes how the Oracle Reference Architecture (ORA) combines different
Technology Perspectives?
A.
A Technology Perspective is a specialized view of ORA focused on a particular set of products
and technology; therefore, the core ORA material represents the combination of all of the
Technology Perspectives.
B.
Each Technology Perspective belongs to an Enterprise Technology Strategy. Each Enterprise
Technology Strategy includes practical guidance on how to combine the strategy with other
Enterprise Technology Strategies.
C.
The composition of different Technology Perspectives is accomplished via Industry
Perspectives. The Industry Perspective illustrates and describes how the different Technology
Perspectives apply to a particular industry vertical.
D.
The composition of different Technology Perspectives is accomplished via SOA Services. The
SOA conceptual model is used to illustrate and describe how each Technology Perspective
consumes and provides SOA Services.
Explanation:
The intent of SOA is to provide common reusable SOA Services that can be
leveraged
by a variety of consumers. SOA Services are made available to various types of service
consumers in order to rationalize the way business functions are performed and
enterprise data is managed. Its modular architecture approach promotes reuse and
business agility, and the use of widely adopted technology standards improves
interoperability between business solutions.
Service consumers consist of various types of business solutions, such as BPM, EDA, MDM, BI.
SOA Services can also act as service consumers.
ORA provides a framework to describe how various technology perspectives are
related.
Note:The reference architecture is designed to support an expanding list of technology strategies.
It is also important that the various technology perspectives can be easily combined since they are
very much complementary.
ORA embraces service orientation at the core so that services provide a consistent
mechanism to expose and combine various technologies and the capabilities.
A high-level conceptual model for SOA is used to illustrate how technology
perspectives consume and provide SOA Services.
