Visualizing design patterns with a UML profile
نویسندگان
چکیده
A design pattern describes a general solution to a design problem that recurs repeatedly in many projects. Software designers adapt the pattern solution to their specific project. Design patterns are usually modeled using UML. However, UML does not keep track of pattern-related information when a design pattern is applied or composed with other patterns. Thus, it is hard for a designer to identify design patterns in software system designs. The benefits of design patterns are compromised because the designers cannot communicate with each other in terms of the design patterns they use and their design decisions and tradeoffs. In this paper, we present the essential features of a new member of the UML language family that supports working with object-oriented design patterns. This UML extension allows the explicit representation of design patterns in software designs. We also discuss some of the relevant aspects of the UML profile which is based on standard UML extension mechanisms. A case study shows how it can be used to assist pattern-based software development.

متن کاملModeling Real-Time applications with Reusable Design Patterns
Real-Time (RT) applications, which manipulate important volumes of data, need to be managed with RT databases that deal with time-constrained data and time-constrained transactions. In spite of their numerous advantages, RT databases development remains a complex task, since developers must study many design issues related to the RT domain. In this paper, we tackle this problem by proposing RT ...
متن کاملA UML-Profile for domain specific patterns: Application to real-time
The design of Real-Time (RT) applications is a difficult task since it must take into account the specification of time-constrained data and timeconstrained transactions. The design of these applications can be facilitated through the reuse of RT design patterns that improve software quality and capture RT domain knowledge and design expertise. However, the difficulty of RT design patterns comp...
متن کاملLeveraging Patterns on Domain Models to Improve UML Profile Definition
Building a reliable UML profile is a difficult activity that requires the use of complex mechanisms -stereotypes and their attributes, OCL enforcementto define a domain-specific modeling language (DSML). Despite the ever increasing number of profiles being built in many domains, there is a little published literature available to help DSML designers. Without a clear design process, most such pr...
متن کاملUML for Real-Time Overview
This paper explains how the Unified Modeling Language (UML), and powerful modeling constructs originally developed for the modeling of complex real-time systems in the Real-Time Object-Oriented Modeling language (ROOM), have been combined into UML for Real-Time. It is directed at developers of complex real-time software systems (e.g., telecommunications, aerospace, defense, and automatic contro...
