Data flow diagram with data storage, data flows, function and interface. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself.
Data reconciliation is a technique that targets at correcting measurement errors that are due to measurement noise, i.e. random errors.From a statistical point of view the main assumption is that no systematic errors exist in the set of measurements, since they may bias the reconciliation results and reduce the robustness of the reconciliation.
In the event-driven process chain, the information, material, or resource objects portray objects in the real world, for example business objects, entities, etc., which can be input data serving as the basis for a function, or output data produced by a function. Examples are "material", "order", etc.
A canonical example of a data-flow analysis is reaching definitions. A simple way to perform data-flow analysis of programs is to set up data-flow equations for each node of the control-flow graph and solve them by repeatedly calculating the output from the input locally at each node until the whole system stabilizes, i.e., it reaches a fixpoint.
After establishing the 'as is' workflow and systems interfaces, work steps are simplified to automate processes whenever practical and transfer steps to subsequent work processes. A 'to be' model is then created for human processes and a related systems design document developed for those that are automated.
Tavaxy [11] is a cloud-based workflow system that implements a pattern-based approach for enabling interoperability between Galaxy and Taverna, two workflow engines popular in the bioinformatics domain, [12] YAWL, Yet Another Workflow Language, Cameleon (programming language), Workflow based graphical language for functional programming.
Anduril is an open source component-based workflow framework for scientific data analysis [2] developed at the Systems Biology Laboratory, University of Helsinki.. Anduril is designed to enable systematic, flexible and efficient data analysis, particularly in the field of high-throughput experiments in biomedical research.
The Common Workflow Language (CWL) is a standard for describing computational data-analysis workflows. [1] Development of CWL is focused particularly on serving the data-intensive sciences, such as bioinformatics , [ 2 ] medical imaging , astronomy , physics , and chemistry .
