The term IT Architecture summarizes all static and dynamic aspects of IT (information technology) in organizations. These aspects include the infrastructure like hardware, software an data as well as the management of IT (configuration and capacity planning, load balancing, data backup, availability, reliability, disaster-planning, etc.). Furthermore functional aspects such as the necessary interfaces that provide a frictionless IT support of the business processes of organizations are part of the IT architecture.
Similarly, as a model information system can be modeled and the company/organization both from a procedural perspective business processes modeling (BPM - Business Process Modeling). As well as the professional-term problem, using Object-oriented analysis and design (OOA&D and UML).
Achitecture of Information System (IT Architecture)
Defines IS as an unit from functional point of view.
is composed by Functional IS architecture model, which provides
conceptual point of view for IS, for an organization activities
towards outside environment which are supported by IS, for
specification of individual subsystems in IS, their connections and
interfaces up to architecture of implementation realization by
specific software applications and data warehouses.
Modeling Techniques for IT Architecture :
• OMG Business Motivation Model
• Business Process Model (BPMN or Catalyst)
• Requirements Management
• UseCase model
• Object Sequence Diagram (UML)
• Class Diagram (UML)
• State Transition Diagram (UML)
• Object Collaboration Diagram (UML)
• Activity Diagram (UML)
• Entity Relationship and ERA diagram
Sequence Diagram (UML) Class Diagram (UML) Physical Data Model
Defines physical environment in which specific information system is implemented and administered.
It describes technical, communication and system infrastructure and by this it creates physical frame for IS as a unit, as well as for individual components and subsystems.
Technical architecture of information system is realized by creation of technical architecture model, which presents mutual relationships, topology and number of technical IS infrastructure components.
IT Architecture, standards and tools
The area of analysis and modeling of functional architecture, as part a Enterprise Architecture are applied these design standards:
• Methods of processing
the functional architecture of the information system (EDEN CONSULTING/LBMS/Select
Business Solutions) based on the methodology Select Perspective and
software tool Select Process Director - for use and maintenance
The methodology is based on
ontological standard / perspectives in the field of modeling Enterprise
Architecture - Zachman Framework.
The area of analysis
and modeling are applied to the TA project standards:
