This article will explain in detail the example analysis of the UML model in RSA. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Overview of RSA UML Model

1 model file

Each model file under the project has a corresponding file name in the file system, with the extension emx.RSA

Support the import of older versions of RationalRose and XDE model files.

Create UML project: file-- > New-- > Project-- > Modeling-- > UML Project-- > Project name (Standard Model)-- > General-- > simplified blank UML package-- > package (free format diagram)-- > next-- > finish.

2 package-based organizational structure

In RSA, the UML model is woven based on package. A package can contain multiple related model elements, as well as the package itself.

The package also contains namespaces, which means that the model element names under the same package must be *.

Packages can be used in a variety of diagrams, such as class diagrams, component diagrams, and use case diagrams.

There is a default diagram under each package, which will be opened automatically when you double-click the package in Project Explorer.

In RSA, if the user creates a new package, it will generate a default image, which will be displayed when you double-click the package, but if the user wants to change the default diagram below the package, right-click the UML diagram that needs to be set as the default diagram, select "generate default Diagram" in the menu that appears, and click.

3 blank model

The blank model in RSA UML model is a blank modeling file, which is not based on any model template. The blank model does not apply a special profile, and there is no default content except a single main diagram (free format). The blank modeling file can be used as the starting point of any type of model.

Create a blank model: right-click Model in the project-- > create Model-- > Standard template-- > next-- > General-- > simplified Blank UML package-- > package (Free format Diagram)-- > next-- > finish

4 use case model

In the RSA UML model, the use case model describes the functional requirements of a system (such as the functions that the system must provide, etc.).

The implemented function (use case), the environment (actor) and the relationship between the use case and the actor. The relationship between use cases and actors can be represented by a use case diagram, which can contain a textual description of the event flow. At the same time, for some complex systems, the activity diagram can be used to represent the event flow in the use case.

Create a use case model: right-click Model in the project-- > create Model-- > Standard template-- > next-- > requirements-- > Blank use case package (use case package)-- > next-- > finish

The two main UML diagrams in the use case model are use case diagrams and activity diagrams.

Use case diagrams include two aspects: actors and use cases.

When establishing the use case model, the activity diagram can be used to model the business process, and in the analysis and design stage, the behavior of a classifier can also be modeled.

5 Analytical model

System analysis is the step of implementing the system, and its purpose is to help sort out the requirements and design at a higher and abstract level, and to have a deep understanding of the system before entering into detailed design.

The analysis model includes class diagram and sequence diagram.

The steps for creating an analytical model are very similar to those for creating a use case model, except that when you select a model template, select

"Analytical model" is fine.

6 Design model

In the RSA UML model, the design model takes the abstract model created in the analysis phase, and adds the details to the real implementation of the system.

Use a variety of diagrams, including sequence diagrams, state diagrams, component diagrams, and deployment diagrams. You can build a design model that describes in detail how the application is constructed.

7 data modeling

RSA not only supports UML modeling, but also supports database modeling. RSA focuses on specific database design and development.
