Activity Diagram for Login and Registration
The UML activity diagram for login and registration is a diagram that presents the flow of system activities. It is one of the methods used to document the system behavior in terms of activities and development.
Additionally, the activity diagram uses symbols to define the overall workflow of the login and registration. It is composed of activities, decisions, and paths (flows).

What are Login and Registration?
A system’s login page requires a user to create a username and password. The system’s registration, on the other hand, provides a form that asks for other security questions. This security information varies as the system owner requires.
The purpose of the system’s registration and login is to validate a user who wants to access the system. During the registration, users will have to submit some personal information to grant access to the system. Then system saves that information which becomes the basis when the users log in to the system.
Define Login and Registration Activity Diagram
UML defines a login and registration activity diagram as a very effective behavior diagram. This diagram shows the flow of interaction between the system and clients. This is done by helping them visualize the system’s functionality in various degrees of detail.
The activity diagram in UML visually depicts a set of actions or control flows of the system’s login and registration. It describes the processes in a use case diagram. Its’ illustration can also be sequential or concurrent.
Additionally, the activity diagram can clarify difficult use cases (use case diagram) to simplify and improve any process. It models the system’s actions, functions, and processes.
Importance of UML Activity Diagram
The use of an activity diagram involves major activities that define the workflow of the project. These activities flow with user decisions that result in more effective interaction. It also visualizes a set of actions or control flows of the login and registration page.
An activity diagram in UML represents the Login and Registration’s major activities and constraints. Then these activities generate a flow that the project should include. Each activity was labeled properly to determine the system’s behavior.
The activity diagram is one of the Login and Registration UML diagrams. It also shows the system’s dynamic behavior. It shows the flow of messages from one activity to another.
Activity Diagram: Benefits
The Activity Diagram Benefits are as follows:
- An Activity Diagram helps in understanding how an algorithm works.
- It also describes the steps that a UML use case takes.
- Shows how users and the system interact in a process or workflow.
- Clarify difficult use cases to simplify and improve any process.
Login and Registration System Activity Diagram
The Login and Registration System Activity Diagram example expounds on the system’s ideas. This activity diagram example using swimlanes is shown in the detailed illustration to enlighten the programmers.
It figures out the activities that happen when a user logs in to a system. This example illustration shows the activities and scenarios done in online booking. Thus, the actions and decisions included were all emphasized here.
As seen in the illustration, we used the swimlane with two partitions. The left portion shows the user lane. It covers all the possible activities of a user when using the system. Its lane also symbolizes the scope of the user’s actions.
Now, the system’s scope and activities were placed on the right lane. This shows that the system acts as the responder to the user’s activities and processes. Therefore, the system is designed to be accessible by the users.
To access the system, the users must have their accounts logged into the software. The functions were then emphasized as the activities flow and the system and users communicate.
You can add more to this and it is up to you how will you create your activity diagram. But, make sure that you have precise information and include the important decisions (actions).

What are the Symbols used in Activity Diagram?
Activity Diagram Symbols – are used not just to draw an activity diagram, but also to emphasize the role of all that was included in the system’s process. Each of the symbols was used to present a certain part of the system.
- Start – is the beginning of the action. It uses a filled circle symbol to show its function.
- Action – is a stage of an activity in which users or software accomplish a certain task. Action is shown in Round-edged rectangles.
- Decision – symbolizes a conditional branch in the flow. It has two or more outputs and a single input. A diamond symbol presents this notation.
- Swim Lanes – are the lanes showing the actor’s boundaries. The activities drew in the same lane considered as the organization’s activities. Swim lanes must be in a logical arrangement.
- Activity Flow – is another name for the connectors in the diagram that illustrate the flow between processes (activity).
- End (Terminator) – is the last phase of the activity. An indicated black circle represents the final node.
Each of these activity diagram symbols shows the overall system behavior. Emphasizing the system’s behavior would also be much easier by using these Activity Diagram symbols.
How to Draw an Activity Diagram?
Time needed: 5 minutes.
Here are the steps in developing (designing) the activity diagram for login and registration.
- Step 1: Familiarize Activity Diagram Symbols
To draw an activity diagram, you need to familiarize yourself first with the symbols used. The symbols let you discuss the system’s flow of activities and interaction. Programmers can also quickly deliver the system’s concept to the users.
- Step 2: Identify the flow of actions.
After familiarizing the symbols used, you will need to identify the flow of actions. The flow of actions would be based on your use case diagram.
Actions describe the sequence or series of activities when a user invokes the system’s login and registration. Moreover, the action represents a discrete unit of functionality in an activity diagram. It also describes the steps in a UML use case diagram.
The incoming and outgoing activity edges of actions specify the control flow of data. Its actions begin when all of the input requirements are met.
- Step 3: Add the Actors (users) involved.
Actors carry out their actions on things, transforming them into other objects or changing their state. This actor is someone or something that interacts with the system from outside the system.
We use “actors” as labels on the swimlanes to indicate that the action or step performed was from them or the system. This way will help readers and developers how will the system behave or interact with actors or vice versa.
- Step 4: Trace the flow of activities.
To trace the flow of activities, make sure that you know that flows can be sequential, branching, or run.
Developers use action or control flows to know the transition from one state of activity to another. There might be several entering and outgoing action flows in this notation.
Furthermore, control flow determines the activity’s flow, and the inbound arrow initiates a single activity step. Upon accomplishing this phase, the flow continues along the outgoing arrow. Object flow also describes the flow of objects (data) within activities.
In conclusion, we have discussed What is an Activity Diagram for Login and Registration and the steps on how to develop it. This activity diagram acts as one of the methodologies for creating the system’s login and registration.
Additionally, an activity diagram stresses the system’s flow of activities and the interactions between the users and the system.
Therefore, using an activity diagram in UML will not only let you understand the project but also tell you the possibilities while designing it. This diagram works best with the other UML Diagrams which are provided in the Recommended Articles. See also other Activity Diagrams in the Related Articles below.
