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.

The control flow is drawn from one operation to another. This flow can be sequential, branched, or concurrent. Activity diagrams deal with all type of flow control by using different elements such as fork, join, etc.

The basic purposes of activity diagrams is similar to other four diagrams. It captures the dynamic behavior of the system. Other four diagrams are used to show the message flow from one object to another but activity diagram is used to show message flow from one activity to another. Activity is a particular operation of the system. Activity diagrams are not only used for visualizing the dynamic nature of a system, but they are also used to construct the executable system by using forward and reverse engineering techniques.

The only missing thing in the activity diagram is the message part. It does not show any message flow from one activity to another. Activity diagram is sometimes considered as the flowchart. Although the diagrams look like a flowchart, they are not. It shows different flows such as parallel, branched, concurrent, and single.

Activity diagrams are mainly used as a flowchart that consists of activities performed by the system. Activity diagrams are not exactly flowcharts as they have some additional capabilities. These additional capabilities include branching, parallel flow, swimlane, etc. Before drawing an activity diagram, we must have a clear understanding about the elements used in activity diagram.

The main element of an activity diagram is the activity itself. An activity is a function performed by the system. After identifying the activities, we need to understand how they are associated with constraints and conditions. Once the above-mentioned parameters are identified, we need to make a mental layout of the entire flow. This mental layout is then transformed into an activity diagram. Following is an example of an activity diagram for order management system.

In the diagram, four activities are identified which are associated with conditions. One important point should be clearly understood that an activity diagram cannot be exactly matched with the code. The activity diagram is made to understand the flow of activities and is mainly used by the business users. After receiving the order request, condition checks are performed to check if it is normal or special order. After the type of order is identified, dispatch activity is performed and that is marked as the termination of the process.

The basic usage of activity diagram is similar to other four UML diagrams. The specific usage is to model the control flow from one activity to another. This control flow does not include messages. Activity diagram is suitable for modeling the activity flow of the system. An application can have multiple systems. Activity diagram also captures these systems and describes the flow from one system to another.UML is a way of visualizing a software program using a collection of diagrams.

The notation has evolved from the work of Grady Booch, James Rumbaugh, Ivar Jacobson, and the Rational Software Corporation to be used for object-oriented design, but it has since been extended to cover a wider variety of software engineering projects. UML 2. The key to making a UML diagram is connecting shapes that represent an object or class with other shapes to illustrate relationships and the flow of information and data.

To learn more about creating UML diagrams:. The current UML standards call for 13 different types of diagrams: class, activity, object, use case, sequence, package, state, component, communication, composite structure, interaction overview, timing, and deployment. These diagrams are organized into two distinct groups: structural diagrams and behavioral or interaction diagrams. They describe the static structure of a system. Learn more.

Watch this short video about UML Class Diagrams Package Diagram Package diagrams are a subset of class diagrams, but developers sometimes treat them as a separate technique.

Diaphragm Overview

Package diagrams organize elements of a system into related groups to minimize dependencies between packages. Object Diagram Object diagrams describe the static structure of a system at a particular time. They can be used to test class diagrams for accuracy. Composite Structure Diagram Composite structure diagrams show the internal part of a class. Use Case Diagram Use case diagrams model the functionality of a system using actors and use cases. Activity Diagram Activity diagrams illustrate the dynamic nature of a system by modeling the flow of control from activity to activity.

An activity represents an operation on some class in the system that results in a change in the state of the system. Typically, activity diagrams are used to model workflow or business processes and internal operation.

Sequence Diagram Sequence diagrams describe interactions among classes in terms of an exchange of messages over time. Interaction Overview Diagram Interaction overview diagrams are a combination of activity and sequence diagrams.For more than a century, Westinghouse has consistently provided innovative, reliable, high-quality products and customer service.

This dome-shaped muscle is located just below the lungs and heart.

It contracts continually as you breathe in and out. The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs. It also has some nonrespiratory functions as well.

The diaphragm increases abdominal pressure to help the body get rid of vomit, urine, and feces. It also places pressure on the esophagus to prevent acid reflux. The phrenic nerve, which runs from the neck to the diaphragm, controls the movement of the diaphragm. There are three large openings in the diaphragm that allow certain structures to pass between the chest and the abdomen.

A hiatal hernia happens when the upper part of the stomach bulges through the esophageal opening of the diaphragm. But a larger hiatal hernia may cause some symptoms, including:.

Larger hiatal hernias sometimes require surgical repair, but other cases are usually manageable with over-the-counter antacid medication. Proton pump inhibitors can also help to reduce acid production and heal any damage to the esophagus.

A diaphragmatic hernia happens when at least one abdominal organ bulges into the chest through an opening in the diaphragm. Injuries from an accident or surgery can also cause a diaphragmatic hernia. Symptoms can vary depending on the size of the hernia, the cause, and the organs involved. They may include:.Breaking News. Government is doing about it. Skip to main content Press Enter.
