A Warnier/Orr diagram (also known as a logical construction of a program/system) is a kind of hierarchical flowchart that allows the description of the organization of data and procedures. They were initially developed 1976, [ 1 ] in France by Jean-Dominique Warnier [ 2 ] and in the United States by Kenneth Orr [ 3 ] on the foundation of ...
A 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 integration , for example, should be dependent upon data architecture standards since data integration requires data interactions between two or more data systems.
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 ...
Data-Flow Diagram example [19] A data-flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the flowchart as it shows the data flow instead of the control flow of the program. A data-flow diagram can also be used for the visualization of data processing (structured design).
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
Core architecture data model (CADM) in enterprise architecture is a logical data model of information used to describe and build architectures. [2] The CADM is essentially a common database schema, defined within the US Department of Defense Architecture Framework DoDAF. It was initially published in 1997 as a logical data model for ...
A Bachman diagram is a certain type of data structure diagram, [2] and is used to design the data with a network or relational "logical" model, separating the data model from the way the data is stored in the system. The model is named after database pioneer Charles Bachman, and mostly used in computer software design.
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 ...
