What is online shopping activity?
Online shopping is the activity or action of buying products or services over the Internet. It means going online, landing on a seller’s website, selecting something, and arranging for its delivery. The buyer either pays for the good or service online with a credit or debit card or upon delivery.
What is activity diagram explain with example?
An activity diagram visually presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram. Activity diagrams are often used in business process modeling. They can also describe the steps in a use case diagram. Activities modeled can be sequential and concurrent.
What is user activity diagram?
Activity diagram is another important diagram in UML to describe the dynamic aspects of the system. Activity diagram is basically a flowchart to represent the flow from one activity to another activity. The activity can be described as an operation of the system.
What is activity sequence diagram?
The Activity diagram represents the UML, which is used to model the workflow of a system. The Sequence diagram shows the message flow from one object to another object. Sequence diagram is mainly used to represent the time order of a process. Activity diagram is used to represent the execution of the process.
What is purpose of activity diagram?
An activity diagram shows business and software processes as a progression of actions. These actions can be carried out by people, software components or computers. Activity diagrams are used to describe business processes and use cases as well as to document the implementation of system processes.
Why do we use activity diagram?
An activity diagram is used by developers to understand the flow of programs on a high level. It also enables them to figure out constraints and conditions that cause particular events. A flow chart converges into being an activity diagram if complex decisions are being made.
What is the difference between state diagram and activity diagram?
Fig. Both activity and state chart diagrams model the dynamic behavior of the system. Activity diagram is essentially a flowchart showing flow of control from activity to activity. A state chart diagram shows a state machine emphasizing the flow of control from state to state.
What is the difference between activity and state diagram?
Both activity and state chart diagrams model the dynamic behavior of the system. Activity diagram is essentially a flowchart showing flow of control from activity to activity. A state chart diagram shows a state machine emphasizing the flow of control from state to state.
What is the difference between activity diagram and class diagram?
Using class diagram you can draw the sequence diagrams to show the interaction between classes. Activity diagram is focused on Actions within the behaviour.
What is the difference between flowchart and activity diagram?
The main difference between activity diagram and flowchart is that activity diagram is a UML behavior diagram that represents the workflow of stepwise activities of the system while flowchart is a graphical diagram that represents the sequence of steps to solve a problem.
How do you describe an activity diagram?
In Unified Modeling Language (UML), an activity diagram is a graphical representation of an executed set of procedural system activities and considered a state chart diagram variation. Activity diagrams describe parallel and conditional activities, use cases and system functions at a detailed level.
Is related with state diagram?
A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems. State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction.
What is the difference between an activity and state?
The difference is that activity diagrams support description of parallel activities and synchronization aspects involved in different activities. A state chart diagram is normally used to model how the state of an object changes in its lifetime.
