Enterprise architecture (EA) is a mechanism for understanding all aspects of the organization, and planning for change. Those aspects include business transformation, business process rationalization, business or capability-driven solution development, application rationalization, transformation of IT to the cloud, server consolidation, service management and deployment, building systems of ...
Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
Context diagrams (level 1): show the system in scope and its relationship with users and other systems; Container diagrams (level 2): decompose a system into interrelated containers. A container represents an application or a data store; Component diagrams (level 3): decompose containers into interrelated components, and relate the components ...
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
Data integration, for example, should be dependent upon data architecture standards since data integration requires data interactions between two or more data systems. A data architecture, in part, describes the data structures used by a business and its computer applications software.
The ARIS concept (Architecture of Integrated Information Systems) by August-Wilhelm Scheer aims to ensure that an enterprise information system can completely meet its requirements. This framework is based on a division of the model into description views and levels, which allows a description of the individual elements through specially ...
Internal Level: The internal level involves how the database is physically represented on the computer system. It describes how the data is actually stored in the database and on the computer hardware. The Three Level Architecture has the aim of enabling users to access the same data but with a personalised view of it.
A data architect is a practitioner of data architecture, a data management discipline concerned with designing, creating, deploying and managing an organization's data architecture. Data architects define how the data will be stored, consumed, integrated and managed by different data entities and IT systems, as well as any applications using or ...
