An activity diagram focuses on condition of flow and the sequence in which it happens. So, we basically depict workflows visually using an activity diagram. We model sequential and concurrent activities using activity diagrams. Design Patterns | Set 2 (Factory Method)We use Activity Diagrams to illustrate the flow of control in a system and refer to the steps involved in the execution of a use case. Singleton Design Pattern | Implementation Difference between Inverted Index and Forward Index

Business processes where decision making is involved is expressed using a flow chart.So, programmers use activity diagrams (advanced version of a flowchart) to depict workflows. We can call a flowchart a primitive version of an activity diagram. For example: A manufacturer uses a flow chart to explain and illustrate how a particular product is manufactured.

Businessmen and Developers to interact and understand systems.Do we need to use both the diagram and the textual documentation?Different individuals have different preferences in which they understand something. So an activity diagram helps people on both sides i.e. We need to convey a lot of information with clarity and make sure it is short. A flow chart converges into being an activity diagram if complex decisions are being made.Brevity is the soul of wit. It also enables them to figure out constraints and conditions that cause particular events.

However, Use cases have a low level of abstraction. An activity diagram can be used to illustrate a business process (high level implementation) to a stand alone algorithm (ground level implementation). So in simple terms, an activity diagram shows ‘How’ while a Use case shows ‘What’ for a particular system.The levels of abstraction also vary for both of them. What the system does and not how it is done. On the other hand, the purpose of a Use Case is to just depict the functionality i.e. We also need to be sensitive to the needs of the audience that we are catering to at times.Difference between a Use case diagram and an Activity diagramAn activity diagram is used to model the workflow depicting conditions, constraints, sequential and concurrent activities.

For objects, this is the state when they are instantiated. We use a black filled circle to depict the initial state of a system. Initial State – The starting state before an activity takes place is depicted using the initial state.Figure – notation for initial state or start stateA process can have only one initial state unless we are depicting nested activities. Activity Diagram Notations –

They are used to show the transition from one activity state to another.An activity state can have multiple incoming and outgoing action flows. Action Flow or Control flows – Action flows or Control flows are also referred to as paths and edges. Basically any action or event that takes place is represented using an activity.For example – Consider the previous example of opening an application opening the application is an activity state in the activity diagram.Figure – activity state symbol being used We represent an activity using a rectangle with rounded corners. Action or Activity State – An activity represents execution of an action on objects or by objects.
