Analysis Sequence Diagram

Posted on by

In this step-by-step tutorial, we'll show you how to make a UML sequence diagram using Lucidchart. Sequence diagrams are a type of Unified Modeling Language. Domain analysis-You can edit this template and create your own diagram.Creately diagrams can be exported and added to Word, PPT (powerpoint), Excel, Visio or any other document. Use PDF export for high quality prints and SVG export for large sharp images or embed your diagrams.

The analysis object model instantiates theEntity-Control-Boundary Pattern (ECB)

ECB is a simplification of the Model-View-ControllerPattern.

ECB partitions the system into three types of classes:entities, controls, and boundaries.

entity, control, and boundary are official UML classstereotypes. UML has some special icons to represent them:

Here's the same diagram without the special icons:


Entities are objects representing system data: Customer,Product, Transaction, Cart, etc.

Boundaries are objects that interface with system actors:UserInterface, DataBaseGateway, ServerProxy, etc.


Controls are objects that mediate between boundaries andentities. Quidco vpn. They orchestrate the execution of commands coming from the boundaryby interacting with entity and boundary objects. Controls often correspond touse cases and map to use casecontrollers in the design model.

Associated with every control in the analysis model is astatechart diagram representing the control's internal logic.
