Computer Science: TOGAF (The Open Group Architecture Framework)

Overview

The open group architecture framework ( TOGAF ) may be a framework and technique for enterprise architecture that provides a methodology to investigate the overall business architecture 4. there may be four domain architecture that would be typically accepted as the main overall enterprise architecture 4. the fourth domain has actually been supported by TOGAF, namely :

1. Business Architecture : this architecture defines the business strategy, rules, organization, and key business processes.

2. Data Architecture : this architecture describes the structure as to firmly the organizations data assets.

3. Application Architecture : the architecture provides a blueprint for application systems deployed, their interactions and also their relation towards the core business processes as to firmly the organization.

4. Technology Architecture : architecture describes the hardware elements as to firmly the software were required to support the business architecture, data and application.

TOGAF ADM ( Architecture Development Method )

the core a part of TOGAF may be a methodology for developing architectural design popularly known as architecture development technique ( ADM). TOGAF ADM has 9 phases 4, namely :

1. Preliminary Phase : Framework and Principles

this phase contains descriptions of preparation and initiation activities needed to customize the enterprise architecture with business referrals. this includes the definition as to firmly the specific architecture framework organization, and therefore the definition as to firmly the principles. principle may be a principle contained within the whole architecture that will certainly be under the architectural direction for our organization.

2. Phase A : Architecture Vision

this phase serves to define the scope, eye-sight, and map out ample strategy within the whole execution architecture. activity that would be in it, as well as the identification of stakeholders, creating architecture eye-sight, and obtain the approval as to firmly the parties concerned. architecture eye-sight contains an explanation of how the capabilities as to firmly the target architecture can help in achieving business goals.

3. Phase B : Business Architecture

this phase contains a description as to firmly the current business architecture ( baseline ) too as the event as to firmly the target business architecture. business architecture describes the strategy of merchandise or services, aspects as to firmly the organization, functions, processes, information, and geographically due to business environment. all aspects are based mostly on business principles, business goals, and strategic tactics.

4. Phase C : Information Systems Architectures

this phase describes information system architecture, as well as the event of data and application architecture. this phase can specialize in the identification and definition as to firmly the architecture of applications and data, that supports business as to firmly the enterprise architecture.

5. Phase D : Technology Architectures

this phase contains a description of the event of technology architecture for our project. phase mapping technology architecture elements are defined within the whole application phase as to firmly the application architecture into elements technology, that may be a element of software and hardware.

6. Phase E : Opportunities and Solutions

this phase can arrive at a final strategy, that sets out what will certainly be purchased, constructed, or re-used, in addition to how the target architecture that has actually been made ; ;will be implemented. at this phase can commence implementation plan and therefore the identification of how the realization as to firmly the architecture has actually been defined within the whole previous phase. this phase has centered upon the structure which can implement the target architecture.

7. Phase F : Migration Planning

phase containing migration plans and comes, that realize a few or most of the architectural transition phase that has actually been identified in e. in detail, this phase offers the formula associated with a detailed set of sequential actions, to take architectural changes to back up implementation and migration plans. this phase can finalize implementation and migration intend to do within the whole organization.

8. Phase G : Implementation Governance

this phase includes activities to take a recommendation towards the entire project implementation, contract architecture to manage the implementation and deployment method, and ensure the answer has actually been deployed successfully. this phase establishes the connection connecting architecture and implementation as to firmly the organization against a contract architecture.

9. Phase H : Architecture Change Management

this last phase system in spot to monitor the changes that ought to actually be done and set a time to start out a fresh cycle, repeat towards the preliminary stage. this phase contains the determination procedures to manage changes towards the new architecture.

10. Requirements Management

requirements management can specialize in the procedure of managing architecture requirements across the togaf adm phases. this method isn't the main base and into center stage upon the overall structure as to firmly the togaf adm. this can be due towards the togaf adm is continuously driven by requirements management method. in it's a dynamic method whereby requirements for enterprise architecture and changes are identified, stored, and used for the appropriate phase as to firmly the togaf adm.

TOGAF ADM with 9 phase essentially offers the following structure :
