Activity Diagram for Use Case is an activity diagram that can take the place of the flow of activities section of a use case description per use case. On the other hand, the purpose of a Use Case is to just depict the functionality i.e. It mainly models processes and workflows. This diagram tells the interaction between the actor and system. Activity diagrams can show how the events in a use case relate to one another, or how a collection of use cases coordinate to represent a business workflow. A UML activity diagram helps to visualize a certain use case at a more detailed level. Typically, an event needs to be achieved by some operations, particularly where the operation is intended to achieve a number of different things that require coordination, or how the events in a single use case relate .

Two players will be associated but sequentially as the steps taken by each player is not in parallel but in sequence in an instance of a chess game. This diagram tells the interaction between the actor and system. More detailed activity diagrams for specific functions or use cases supported by the system would likely fit into the operations section. Activity diagrams are often used in business process modeling. It encapsulates the system's functionality by incorporating use cases, actors, and their relationships. Activity diagrams can show how the events in a use case relate to one another, or how a collection of use cases coordinate to represent a business workflow. Activity diagrams include swimlanes, branching, parallel flow, control nodes, expansion nodes, and object nodes. Use case diagram and activity diagram. Organized according to Actions, the Activity diagrams mainly depict the internal behavior of a method, i.e. An event is created as an activity diagram encompassing a group of nodes associated with edges. use case merupakan sebuah teknik yang digunakan dalam pengembangan sebuah software atau sistem informasi untuk menangkap kebutuhan fungsional dari sistem yang bersangkutan, use case menjelaskan. Use case diagram and activity diagram are behavioral UML diagrams that describe the dynamic nature of a system. Typically, an event needs to be achieved by some operations, particularly where the operation is intended to achieve a number of different things that require coordination, or how the events in a single use case relate . Each use-case correspond to a set of behaviors that may be performed in interaction with the actors for helping them achieving their goals. Activity diagrams are considered behavior diagrams because they describe what must happen in the system that is being modeled. Why use Activity Diagram?

But I am new to the activity diagrams, and am not sure that it represents the intended flow correctly (i.e. On the File tab, point to New. An activity diagram is used to model the workflow depicting conditions, constraints, sequential and concurrent activities. The flow of events of a use case describes what needs to be done by the system to provide value to an actor. On the other hand, the purpose of a Use Case is to just depict the functionality i.e. In projects in which use cases are present, activity diagrams can model a specific use case at a more detailed level. USE CASE AND ACTIVITY DIAGRAMS 2 Use Case and Activity Diagrams A use case diagram is a simplified representation of how users interact with a given system that uses simple graphics to illustrate the events that takes place.
