storage, you do not need to name the data flowing out. Each Data Stream must have a proper name to reflect the meaning of the data stream. Processing: Processing describes the transformation between the input data stream and the output data, that is, after which the input data stream is converted into the output data. Each processing task has a name and a number. The number indicates the layer and graph of the data flow graph in which the processing

information transformation and transmission in the problem. It regards the system as a combination of various concepts associated with data streams, uses decomposition and abstraction to control the complexity of demand analysis, and uses hierarchical data flowcharts to represent a complex system. Data Flow Diagram: DFD is a graphic representation of the system's logical functions, the logical

Vivid 3D effects: with linear and path gradients, it's easy to create, glow, shadow, Emboss, gel buttons, and even 3D effects. Better performance: Vg.net's animation algorithm ensures that each redraw will draw only the smallest, changing parts and supports hardware acceleration. objects in a vector graph use only very small memory, most of the properti

child elements "inherit" the appearance unless they have the same properties. Style object: Attach a Style object to a picture, modify the appearance, name of any style object defined on the picture, and, by referencing the appearance of a child element, each Style object contains a fill, stroke, text appearance, and appearance rendering properties. Transparency: Sets the fill, stroke, text appearance, and image object. Vivid 3D effects: with linear and path gradients, it's easy to create

is often a certain relationship between these data streams. The relationship is as follows: Third symbol: data storage file: it is usually represented by a dual horizontal line, but the representation of the data storage file is different in different teaching materials. For example, it is represented by a double horizontal line or a half-framed line. The arrow indicates the process of saving or removing the line, indicating the process of reading and writing. Generally, the file name is writt

The basis of software requirement analysis: the model analysis method. The structured analysis method is applicable to the demand analysis of data processing software. It provides the following modeling tools: data flow diagram, data dictionary, machine learning English language, decision table, and decision tree. Th

parameters can not increase or decrease. Although it is sometimes permissible to add new operations, the semantics (or behavior) of the operation should remain the same.Implementation--The implementation of the component can be arbitrarily changed according to the underlying database, algorithm (such as sort) used, as long as the behavior of the customer's concern is not affected, and can even be written in different programming languages.Use case diagrams are a brief description of the externa

data. Each processing has a name and a number. The number can reflect the level of the processing in the hierarchical flow chart and which diagram, can see it is by which processing decomposition of sub-processing. Data storage: Data storage represents data that is temporarily stored. Each data store has a name. External entity: An external entity is a person or organization that exists outside the

Data Flow Diagram (DFD) is one of the most common structural analysis tools, graphically depicts the data movement in the system. The data flow diagram has four basic components, as shown in Figure 1.3. Figure 1.3 Basic components and symbols of a data flow chart Data
