Soa and Framework

service-oriented architecture (SOA): Focuses on communication between

services, such as dissimilar applications. Simple Object Access Protocol

(SOAP), Extensible Markup Language (XML), and Web services are examples

of SOA technologies.

The emergence of service-oriented architecture (SOA) marks an enterpriselevel

approach to application design. SOA utilizes a common set of guiding

principles including modularity, granularity, interoperability, and reusability.

Additional qualities, such as abstraction (where application function is

hidden from the consuming component) and discoverability, enhance efficient

use of service resources across the expanding enterprise.

Zachman Framework

The Zachman Framework is a high-level model developed by the Zachman

Institute. It contains no methodology or processes; instead, it focuses on

views, definitions, relationships, and objects, both physical (such as equipment

or facilities) and conceptual (such as a business unit or an enterprise).

It asks the simple questions of who, what, how, when, where, and why as

they apply to concepts such as scope, business processes, requirements,

solutions development, and deployment. The Zachman Framework is an

excellent starting point for mapping out architecture processes and for identifying

gaps. More information on the Zachman Framework is at www.

TOGAF

The Open Group Architecture Framework (TOGAF) was developed by the

Open Group, a platform-neutral, vendor-neutral consortium whose members

include vendors, colleges and universities, and technology companies.

TOGAF consists of a methodology as well as a modeling system and is

compatible with other enterprise architecture frameworks. Its architecture

development method begins with analysis and ends with an implemented

enterprise architecture.
