The distinctive qualities and clear advantages
of open technology architecture are illustrated in the comparison
to traditional technology architecture. Click to open and close
each differentiator for more information.
The abstraction
and separation of systems into components that are
unified horizontally across independent presentation,
middleware, business logic and data tiers.
•
Composite applications
that combine the capabilities of multiple systems
into a unified system.*
•
Business-focused system
with vertically-linked presentation, business logic
and data functionality.
•
No access to lift out
or reuse shareable components or to build new functionality
into existing components.
* Gartner, "Composite
Applications Head Toward the Mainstream," M. Pezzini,
(16 October 2003).
A foundation
of industry-standard technologies – including
Web services, WSDL/SOAP, XML and J2EE – that
foster interoperability and integration, both across
the enterprise and with partners.**
•
Exclusive, provider-owned
technology with unique, unleverageable and limited
integration parameters.
** UK Office of Government
Commerce, "Success Delivery Toolkit, Version 3.91,"
(May 2003).
Best-in-class
functionality encapsulated to allow service sharing
across the enterprise and to allow PFPC products
to be easily combined with each other, with your
own legacy systems and with third-party products.
An overarching
approach focused holistically on the complex interactions
between systems, enabling integration both within
the enterprise and across boundaries.††
•
Only an enterprise-wide
open architecture can integrate disparate systems
and subsystems into a coherent “composite system”
that optimizes total functionality and performance.
•
The tactical focus
on the features, functionality and benefits of a
specific system – independent of any other
system – supporting siloed business.
