#Activity diagrams software#
There are many software available online which are helpful in drawing the UML Activity Diagrams like SmartDraw, etc. The most important part of using these diagrams is anyone can draw them according to the flow and at almost every step of the software system development life cycle. The person who knows the notations correctly can easily draw the UML activity diagrams. All the complex stages can be displayed very easily. It is very useful in documenting and depicting visualizing the exact process and steps involved in the developmental process. So, in all, we can say that UML Activity Diagrams are necessary during and before the development of any software system.
Import the new packages which are needed for the project. Create New Project & Save the project under a unique name. #Activity diagrams android#
We’ll consider an example of developing software in Android Studio:

How to make a UML Activity Diagram with Example The symbols used in the UML activity diagram is given in the below table:
The only drawback is the UML Activity Diagram is the messages or the communications between two components, or the user cannot be shown. The workflow of the user and the system and user with the system is explained in detail. The understanding of system requirements is explained in a lucid and simple manner. Simplified view, though the complex system. Business processes and flows can be depicted easily. Methods, functions, and operations can be explained in detail. Each and every activity flow in the system can be explained as it is. Complex stage or steps in a software system can be explained easily diagrammatically. This is where the activity ends in a software system ends.Īdvantages and Disadvantages of UML Activity Diagramįollowing are some advantages and disadvantages of the UML activity diagram: Advantages: This is the last stage of the UML activity diagram. But first, we need to have tomatoes and spinach for it. Two results are obtained from two activities, and one result is obtained.Įxample: There is a requirement for the sandwich. In joining, there is more than one input, but only one output is obtained. So, this is a perfect example of a fork.Ī join is one where two results of concurrent activities add and form a single result. So, here the input is the same, that is of vanilla ice cream, but the output results are different. Now, both of them buy the same vanilla flavor, but one of them wants choco-dip, and others want to have fruities to be put upon it. A person tends to buy ice cream for himself and his friend. It generally includes a single input but may or may not get one output.Įxample: There’s one ice cream shop. It is drawn as a diamond shape with multiple inputs and outputs.Ī point from where two concurrent or parallel processes are executed or run, or processed. So this is the condition in the activity diagram. Now, if he chooses, Vanilla flavor, server 1 has to give it to him, else he chooses other flavors, then others have to serve it to him. A person enters into that shop and wants to buy one of the many options available. Or there are two or more conditions that can be considered at the point of the software system.Įxample: There’s an ice cream shop. A single-headed arrow is used to depict the control flow.Ī conditional node or a decisional node is one where there are multiple options available. 
One action state can have multiple control flows input and also output to another action state. Generally depicted with the rounded-edged rectangle.Ĭonnectors between two states or two actions to depict the flow. It represents an action that is going to take place at this stage of the software system. Start Node is the starting point of any activity.Ī step in which the users or software performs a certain task. The initial state is yet to be used or modified in the activity. Symbols and Components of UML Activity Diagramīeforehand, one must have knowledge of how to draw the UML activity diagrams, and for it, the following components and symbols are needed. At the time of execution, the software system must function according to the required flow, so according to it, activity diagrams depict it as forward and reverse engineering process/actions. It is a pictorial representation of how the software system is going to function. Now, how are they different from UML diagrams? So activity depicts what action is going to take place in the process.
Web development, programming languages, Software testing & othersĪ UML Activity Diagram is a behavioral diagram out of the above-mentioned three types of UML diagrams.
