The latest version is presently available at http: Software design is a cognitively challenging task. Designers must manually enter designs, but the primary difficulty is decision-making rather than data-entry. If designers improved their decision-making capabilities, it would result in better designs.
Current CASE tools provide automation and graphical user interfaces that reduce the manual work of entering a design and transforming a design into code. They aid designers in decision-making mainly by providing visualization of design diagrams and simple syntactic checks.
Also many CASE tools provide substantial benefits in the area of version control and concurrent design mechanisms. One area of design support that has been not been well supported is analysis of design decisions.
And they support the design process in that they allow the designer to enter diagrams in the style of popular design methodologies. But they typically do not provide process support to guide the designer through the design task. Instead, designers typically start with a blank page and must remember to cover every aspect of the design.
ArgoUML is a domain-oriented design environment that provides cognitive support of object-oriented design. ArgoUML provides some of the same automation features of a commercial CASE tool, but it focuses on features that support the cognitive needs of designers. These cognitive needs are described by three cognitive theories:. ArgoUML was originally developed by a small group of people as a research project.
It is written in Java and runs on every computer which provides a Java 2 platform of Java 1. This manual is the cumulative work of several people and has been evolving over several years. Connected to the release 0.
UML – Tools & Utilities
These changes were mostly to adopt the manual to the new functions and appearance of ArgoUML version 0. The users and developers that have contributed by providing valuable input, such as review comments or observations while reading and using this manual are too many to name.
Your comments will help us improve things. With it has come a major shift in the thought processes of all involved in the software development life cycle.
These languages provided support for both OO and procedural programming. Object Oriented programming became mainstream. An OO system is designed and implemented as a simulation of the real world using software artifacts.
This premise is as powerful as it is simple. By using an OO approach to design a system can be designed and tested or more correctly simulated without having to actually build the system first. It is the development during the ‘s of tools to support Object Oriented analysis and design that moved this approach into the mainstream.
The popularity of object based and object oriented graphical languages such as Visual Basic and Java reflect the effectiveness of this approach. ArgoUML was conceived as a tool and environment for use in the analysis and design of object-oriented software systems. In this sense it is similar to many of the commercial CASE tools that are sold as tools for modeling software systems. ArgoUML has a number of very important distinctions from many of these tools.
ArgoUML draws on research in cognitive psychology to provide novel features that increase productivity by supporting the cognitive needs of object-oriented software designers and architects.
In this respect, ArgoUML is still ahead of many commercial tools. This allows ArgoUML to run on all platforms for which a reliable port of the Java2 platform is available. ArgoUML is an open source project.

The availability of the source ensures that a new generation of hutorial designers and researchers now have a proven framework from which they can drive the development and evolution of CASE tool technologies.
The result is a solid development tool and environment for OO systems design. Further, it provides a test bed for the evolution of object oriented CASE tools development and research. A first release of ArgoUML was available in and more thandownloads by mid show the impact that this project has made, being popular in educational and commercial fields.
Jason Elliot Robbins founded the Argo Project and provided early project leadership. While Jason remains active in the project, he has handed off project leadership. The project continues to move forward strongly. There are more than members on the developer mailing list see http: This is the place where all the discussion on the latest tasks takes place, and developers discuss the directions the project should take.
Although controversial at times, these discussions are always kept nice and friendly no flame-wars and suchso newbies should not hesitate and participate in them. You’ll always get a warm welcome there. If you want to learn some details about how the project is run and how you should go about to contribute go the the ArgoUML Web Site Developer Zone and read argoulm the documentation there.
The Cookbook is an important document.
Besides the developer mailing list, there’s also a mailing for users see The ArgoUML Mailing List Listwhere we can discuss problems from a user perspective. Developers also read this list, so there’s a good chance to get qualified argiuml. The intention is that this document will provide a comprehensive guide, enabling designers to use ArgoUML to its full extent.
It is in two parts. In this guide there are some things you will not find, because they are covered elsewhere. As each UML concept is encountered, its use is explained. Its use within ArgoUML is then described. Finally the a study is used to give examples of the concepts in use. Eventually ArgoUML will link directly to this argoumo when giving advice tutoriql critics.
– A tutorial about ArgoUML, an uml tool. Installing ArgoUML Includes examples.
A complete Glossary is provided. Please tell us what you think about this User Manual. Your comments will help us make improvements. In case you would like to add to the missing chapters you should contact the ArgoUML Developer Mailing List to check whether noone else is working on this part. You can subscribe to agrouml of the mailinglists via the ArgoUML web site. This release of the manual assumes the reader is very familiar with UML already. This is reflected in the sparseness of the description of UML concepts in the tutorial.
The case study is described, but not yet fully realized throughout the tutorial. This will be achieved in future releases of the manual. Object orientation as a concept has been around since the ‘s, and as a design concept since However it was in the ‘s that it started to develop as a credible alternative to a functional approach in analysis and design. We can identify a number of drivers.
The development of powerful workstations, and with them the emergence into the mainstream of windowing operating user environments. A number of very public major project failures, suggesting that current approaches were not satisfactory. During the early ‘s it became clear that these approaches had many good ideas, often very similar.
UML was conceived as a common notation, that would be in the interests of all involved. The original standard was driven by Rational Software www. Arfouml produced documents describing UML v0. A first proposal, 1. The current titorial version is UML v1. It does not prescribe any particular process. Whatever process is adopted, it must take the system being constructed through a number of phases.
UML – Tools & Utilities
This is where we identify the requirements for the system, using the language of the problem domain. We take the requirements and start to recast them in the language of a putative solution—the solution domain. At this stage, although thinking in terms of a solution, we ensure we keep things at a high level, away from concrete details of a specific solution—what is known as abstraction. We take the specification from the Analysis phase and construct the solution in full detail.
We are moving from abstraction of the problem to its realization in concrete terms. We take the actual design and write it in a real programming language. This includes not just the programming, but the testing that the program meets the requirements verificationtesting that the program actually solves the customer’s problem validation and writing all user documentation.
In this section we look at the two main types of process in use for software engineering. There are others, but they are less widely used. In recent years there has also been a move to reduce the effort required in developing software.
