NetBeans IDE是当前市场上最流行的、开源且免费的集成开发工具。使用NetBeans不仅可以开发Java程序.还提供了对UML的全面支持。利用NetBeans UML建模模块,可以创建八种类型的UML图,极大地方便了开发人员编写程序。本文首先介绍了NetBeans和UML的基本知识;其次着重介绍了如何在NetBeans IDE中实现UML建模;最后,通过创建一个酒店系统的用例图实例加深理解。 相似文献

Software developers would rather not have to learn multiple interfaces and programming environments to work with different vendors' tools. This has encouraged the use of the multivendor integrated development environment (IDE). The article discusses the case for the development of a Java IDE. It describes 2 candidate IDE, NetBeans and Eclipse. Oracle has submitted to Sun a compromise Java IDE proposal designed to work with both NetBeans and Eclipse. 相似文献

UML活动图在工作流过程建模中的应用研究 总被引:11,自引:4,他引:11
UML(Unified Modeling Language)是一种定义良好、易于表达、功能强大且普遍适用的建模语言,其引入活动图的目的之一就是用于企业建模或描述工作流。根据具体应用需要,对活动图的子过程活动、逻辑连接符、控制流边等进行了扩展,给出了扩展后UML活动图的数学模型。 相似文献

Pure embedding as an implementation strategy of domain-specific languages (DSLs) benefits from low implementation costs. On the other hand, it introduces undesired syntactic noise that impedes involvement of non-programming domain experts. Due to this, pure embedded DSLs are generally not intended for, nor used by, non-programmers. In this work, we try to challenge this state by experimenting with inexpensive customizations of the host IDE (Integrated Development Environment) to reduce the negative impact of syntactic noise. We present several techniques and recommendations based on standard IDE features (e.g., file templates, code folding, etc.) that aim to reduce syntactic noise and generally improve the user experience with pure embedded DSLs. The techniques are presented using a NetBeans IDE case study. The goal of the proposed techniques is to improve the user experience with pure embedded DSLs with a focus on the involvement of non-programming domain experts (or non-programmers in general). The proposed techniques were evaluated using a controlled experiment. The experiment compared a group using Ruby and non-modified RubyMine IDE versus a group using Java and NetBeans IDE customized to use the proposed techniques. Experiment results indicate that even inexpensive host IDE customizations can significantly alleviate issues caused by the syntactic noise: Java with its inflexible syntax performed better than Ruby with its concise syntax. 相似文献

Software modeling is a key activity in software development, especially when following any kind of Model Driven Software Engineering (MDSE) process. In this context, standard modeling languages, like the Unified Modeling Language (UML), and tools for supporting the modeling activities become essential.The aim of this study is to analyze how modelers build UML models and how good modeling tools are in supporting this task. Our goal is to draw some useful lessons that help to improve the (UML) modeling process both by recommending changes on the tools themselves and on how UML is taught so that theory and practice of UML modeling are better aligned.Our study employs two research approaches. The main one is an empirical experiment (which analyzes screen recordings registered by undergraduate students during the construction of a UML class diagram). An analytical analysis complements the previous experiment. The study focuses on the most frequent type of UML diagram, the class diagram, and on two tools widely used by the modeling community: MagicDraw and Papyrus. 相似文献

UML活动图的操作语义 总被引:1,自引:0,他引:1
越来越多的系统采用UML(unified model language,统一建模语言)作为建模语言来进行系统分析和设计.UML活动图是UML语言中描述系统动态行为的一种方法,它广泛地运用于业务建模.由于UML活动图缺乏精确的动态语义,所以不利于对其所描述的系统进行形式化的分析、验证和确认.为解决这一问题,根据UML1.5语义文档,给出UML活动图的形式化操作语义.首先给出UML活动图的形式化的语法,然后详细地定义了活动图的格局和变迁,最后基于LTS给出了活动图的演绎规则.主要工作是:引入状态包的概念,使得描述更加清楚、完善;通过LTS定义活动图的操作语义,并详细阐述演绎规则,从而获得活动图的全局状态转移图,使定义的操作语义很容易地应用到形式化验证中.该语义覆盖了UML活动图的绝大部分特征,为对UML活动图进行模型检验奠定了基础. 相似文献
