Example:
(1) There is a DFD diagram below, where the interval between the vertical dotted line input, transformation, and output, Please convert it into a SC diagram:
Solution: we can see from the figure that the left side of the first vertical dotted line is the input part, the center is the transformation part, and the edge is the output part. As a result, we can know that the level-1 SC

In the previous article "UML System Analysis and Design 02-use case diagram and activity diagram (I)", we mainly explained the use case analysis and drawing methods and techniques in requirement analysis, however, the use case diagram only tells us what the system wants to do. As for how to do it, there is no intuitive description. To better illustrate how our sy

ObjectiveMost of the UML describes the logic and design of the information. The implementation diagram is used to describe the realization of the narrative information. The implementation diagram contains a deployment diagram and a component diagram.Component diagram1. ConceptComponent diagram describes the main functi
Use case diagram is used in the requirement Analysis stage, describes the functional requirements of a system to be developed, the use Case view emphasizes the function of the system, and is the first design view of the software development design process. It describes the user's snowball from the user's point of view, describing the function of the system, and pointing out the performer of each function and what functions the performer has completed.

Time series diagrams (Sequence Diagram), also known as sequence or sequential plots, are UML behavior diagrams.
It shows the dynamic collaboration between multiple objects by describing the chronological order in which messages are sent between objects. It can represent the sequence of behavior of a use case, and when a routine is performed, each message in a sequence diagram correspo
1. What is a sequence diagram
is an interaction diagram that emphasizes the time order of messages. A sequence diagram describes the interaction between classes and classes in a class system, and it models these interactions as message exchanges. A sequence diagram is a model that describes how objects collaborate over
The state diagram is one of the diagrams of modeling the dynamic aspects of the system in UML, which describes the dynamic behavior of object state over time by establishing the life cycle model of the object. The state of an object in the system is easiest to discover and understand, so the first thing to consider is the flow of control based on the state. Specifically, a state diagram is used to describe
