Figure 23: Sequence diagram: Database request. In the user authentication process we describe, the messages show how a user enters information into the browser to gain access to the webpage and how the web browser will then cross-check credential to the designated application. In PlantUML sequence diagrams, the -> sequence denotes a message sent between two participants, which are automatically recognized and do not need to be declared beforehand. DataHighway sends a sample to the diagram, which is contained in the Viewer. What information is passed from one object to another? In the case of searching for a product, a Sequence Diagram illustrates, in a visual format, the order of messages exchanged between objects such as the user, UI. The other set of components you must identify are the messages the objects will send. The objects, sometimes called actors, are the principal players that perform tasks and send messages.įor example, in a login sequence, two of the objects would be the potential visitor or user and the login page a visitor uses to interact with the platform they’re attempting to log into. You can easily edit this template using Creately. Visualize sequence of messages between objects in an interaction with Createlys sequence diagram template. ![]() The first necessary set of components are the objects. An interaction between a customer, ticket seller, database and printer. Use Creately’s easy online diagram editor to edit this diagram, collaborate with others and export results to multiple image formats. To accomplish these goals, you must first identify the components of your system that should be diagrammed. These are used to help you visualize the various structures that make up a. Map out a real or hypothetical scenario that has many different components. Let’s take a closer look: Structural diagrams Structural diagrams represent the static structure of software or a system, and they also show different levels of abstraction and implementation. See how objects and components interact with each other in sequence to complete a process. ![]() In this example, the actor User sends a synchronous request to the System, which then responds with a synchronous response. Model how a complex procedure or system operates. Heres an example of a simple sequence diagram created using PlantUML: startuml left to right direction actor User User -> System : Request () System -> User : Response () enduml. You can export it in multiple formats like JPEG, PNG and SVG and easily add it to Word documents, Powerpoint (PPT) presentations, Excel or any other documents. You can accomplish several critical tasks with a sequence diagram. Use Creately’s easy online diagram editor to edit this diagram, collaborate with others and export results to multiple image formats. ![]()
