emergency procedures, data imports, data backups, external transfers of data). It is also important to design interfaces to the data by other systems, as well as a design for the infrastructure that is to support common data operations (i.e. In addition, a description of the database technology to be employed must be generated, as well as a description of the processes that are to manipulate the data. Also, the methodologies that are to be employed to store the data must be defined. For example, an administrative structure that is to be established in order to manage the data resources must be described. Database architecture is a schema of the actual database technology that would support the designed data architecture.Ĭertain elements must be defined during the design phase of the data architecture schema. Physical data architecture encompasses database architecture. The technology plan is focused on the actual tangible elements to be used in the implementation of the data architecture design. Physical data architecture of an information system is part of a technology plan. A data entity is any real or abstract thing about which an organization or individual wishes to store data. The primary requirement at this stage is to define all of the relevant data entities, not to specify computer hardware items. The major types and sources of data necessary to support an enterprise should be identified in a manner that is complete, consistent, and understandable. In this second, broader sense, data architecture includes a complete analysis of the relationships among an organization's functions, available technologies, and data types.ĭata architecture should be defined in the planning phase of the design of a new data processing and storage system. Semantic model or Conceptual/ Enterprise data model List of things and architectural standards important to the business The "data" column of the Zachman Framework for enterprise architecture – Physical - the realization of the data mechanisms for a specific type of functionality.Logical - represents the logic of how entities are related.Conceptual - represents all business entities.The data architect breaks the subject down by going through three traditional architectural stages: The data architect is typically responsible for defining the target state, aligning during development and then following up to ensure enhancements are done in the spirit of the original blueprint.ĭuring the definition of the target state, the data architecture breaks a subject down to the atomic level and then builds it back up to the desired form. It provides criteria for data processing operations to make it possible to design data flows and also control the flow of data in the system. Data architectures address data in storage, data in use, and data in motion descriptions of data stores, data groups, and data items and mappings of those data artifacts to data qualities, applications, locations, etc.Įssential to realizing the target state, data architecture describes how data is processed, stored, and used in an information system. A data architecture, in part, describes the data structures used by a business and its computer applications software. Data integration, for example, should be dependent upon data architecture standards since data integration requires data interactions between two or more data systems. Overview Ī data architecture aims to set data standards for all its data systems as a vision or a model of the eventual interactions between those data systems. Data is usually one of several architecture domains that form the pillars of an enterprise architecture or solution architecture. JSTOR ( November 2008) ( Learn how and when to remove this template message)ĭata architecture consist of models, policies, rules, and standards that govern which data is collected and how it is stored, arranged, integrated, and put to use in data systems and in organizations.Unsourced material may be challenged and removed.įind sources: "Data architecture" – news Please help improve this article by adding citations to reliable sources.
