Data flow refers to how data moves through a computing application. Data flow diagrams (DFDs) map how data is transmitted and are essential in architecture design. Data flow analysis examines a company’s data, while network engineers manage the flow of data packets on a computer network. Data flow programming is used in accounting and finance applications. A data flow diagram should also define error handling processes.
In computing, data flow refers to the way data moves through a computing application. This process maps how data flows from one module to another within a program. This typically starts with data entered on a computer screen and ends with a data storage device.
Data flow design is based on special software diagrams called data flow diagrams (DFDs). These diagrams graphically map how data is transmitted through a computer program. DFD is essential in architecture design because it defines what data is needed to complete specific business functions.
The data flow diagram approach has been used for several decades and provides insight into how data is manipulated within a program. Most DFDs are required as standard practice in design documentation for software programs.
Data flow analysis is a computer engineering job in which a company’s data is examined. This analysis helps a company determine what data is available for reporting and dissemination purposes. The analyst typically prepares graphs and workflows that define how data is used by computer programs.
A network engineer manages the flow of data packets on a computer network. This person ensures that information moves smoothly through the company’s computer network. Most network engineers rely on data flow diagrams to determine potential data bottlenecks in software applications.
Network traffic patterns and data packet sizes are also important for network data flow analysis. Understanding them helps a business determine the volume and bandwidth requirements of a computer network. The size and frequency of the data determine the amount of bandwidth required.
Data flow programming is often used in accounting and finance applications. These programs link mathematical equations to specific fields on a computer screen. When the user changes the value of the field, the equation automatically calculates the appropriate value for another data item. This is often seen in tax preparation software.
A data flow diagram should also define how data is changed during an error situation. This helps designers determine where error handling processes are needed. This negative logic design helps ensure that the system works as intended in both positive and negative situations.
