A customer has two separate lines of business and each has its own unique resources that
are controlled independently. The customer wants to provide a single user interface at the
enterprise level that, at least from the user’s perspective, unifies the separate lines of business
and presents a single consistent view. What is the most suitable architectural arrangement for
such a federated deployment?
A.
The enterprise implements full client stack and part of the service stack while each LoB deploys
the remaining part of the service tierin order to expose uniform interface elements.
B.
The client tier assimilates the data from the resource stack of each line of business.
C.
The enterprise implements full client and service stacks while each LoB deploys a partial
service. sufficient to expose uniform interface elements.
D.
The client tier assimilates the data from the service stack of each line of business.
Explanation:
Each line of business has its own resources that are unique to the line of business
and are controlled by that line of business. The enterprise wants to provide a single user interface
that, at least from the user’s perspective, unifies the separate lines of business.
In this example, the enterprise wide user interface deployment is a full featured user
interaction architecture (i.e. it contains all of the capabilities defined in the Logical
View). Each line of business deploys limited functionality since the only functionality
required is the functionality to create interface elements exposing the resources of that
line of business. The enterprise wide user interface then uses the interface elements
provided by the lines of business to create a unified user experience.The interface elements provided by the lines of business are Remote Providers
to the enterprise user interface. This deployment allows the lines of
business to maintain control of their respective resources since the only access to the
resources is via the interface elements that they create.
