This article is about the difference between EA and Rose in UML modeling tools. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Comparison of UML Modeling tools

Since the official release of UML in 1997, a large number of commercial UML modeling CASE tools have appeared. This not only provides us with a lot of choices, but also requires us to do a lot of research on choosing the right UML modeling tools to better meet the needs of our business and software application development and achieve a return on investment (ROI). In this article, we will compare the UML modeling capabilities, bi-directional engineering features, and project lifecycle support of two CASE tools: EnterpriseArchitect (EA) Professional Edition V.3.51 of SparxSystems and RationalRose Enterprise Edition V.2002 of IBMRational.

Why do we need UML modeling CASE tools?

Today, the construction of the system is becoming more and more complex, and UML modeling CASE tools provide many benefits to project stakeholders (such as project managers, analysts, designers, architects, developers, etc.). UML modeling CASE tool allows us to apply standard methods and theories of object-oriented analysis and design, away from the entangled source code, to achieve the level that construction and design become more intuitive, easier to understand and modify. In large projects, it is more important to use CASE tools. By using the CASE tool:

◆ uses the use case model to capture business / system requirements for business / system analysis.

The design model made by ◆ designers / architects can clearly express the interaction between objects or subsystems in the same layer at different levels (typical UML diagrams such as class diagrams and interaction diagrams).

◆ developers can quickly turn a model into a runnable application, find a subset of classes and methods, and understand how they interact.

The model is seen as the final manual for blueprints and building systems. Similarly, modeling is the ability to consider the presentation of a design and understand how it works at a high level and in an appropriate form.

For these reasons, UMLCASE tools and corresponding methodologies provide us with a way to describe systems that are too complex to understand the underlying source code, while allowing us to develop the right software solutions faster and cheaply.

Of course, CASE tools should be considered in terms of UML modeling capabilities, project lifecycle support, two-way engineering, data modeling, performance, price, supportability, ease of use, and so on. This article will explore the similarities and differences between Rose and EA in the areas of UML modeling, project life cycle support, and two-way engineering, hoping to help you choose the right tools in your project.

The UML standard consists of three parts, namely: building blocks (such as objects, classes, messages), relationships between building blocks (such as associations, generalization), and diagrams (such as activity diagrams). UMLprofile uses the UML extensibility mechanism to extend standard UML symbols, that is, stereotypes, dimension values, and constraints. EA Professional Edition V.3.51 and RationalRoseV.2002.05 both support eight standard UML diagrams of UML1.4 nine diagrams-use case diagram, class diagram, sequence diagram, collaboration diagram, activity diagram, state diagram, implementation diagram (component) diagram, deployment diagram, and several UMLProfiles. If necessary, object diagrams can be created using collaboration diagrams. The differences only exist in the features supported when creating UML diagrams (Table 1) and extending UMLprofiles.

EnterpriseArchitect has a general UMLprofile mechanism for loading and running different Profiles. EnterpriseArchitect specifies a XML file in a specific format for UMLprofiles. In RationalRose, however, you need to generate an additional item. Table 2 shows the availability of UMLprofiles in EA and Rose.
