问题 Could I please get some feedback on this UML diagram? It's a simplified diagram only showing the layout and interconnectivity of the classes with instance variables, constructors and methods intentionally left out at this point in time. Inventory Project Simplified UML Diagram The main thing I need guidance with is the object-oriented design.

阅读更多关于 Project and software analysis - where to begin?

问题 Recently i took project and software analysis lessons. At first i found the subject kinda boring but then i began to see the importance of them. Modeling is pretty important. My teacher showed us some basic diagrams: classes, use cases, sequence and statemachine. It was only 7 lessons and now i want to pursue further education on the subject. As a developer, i think it would improve my work. Where do i begin? Any books or web sites? I'm still pretty much a newbie at it so please, not too much

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post.

Convert UML To Java

问题 i searched several forums and google in turn but couldn't find a proper way to do this. any help would be welcome. 回答1: The UML conversion to java is really very poor. Except Omondo using either diagram<>model<>code live synchronization or diagram<>model live synchronization and then merge of UML and Java Ids in order to deliver quality code all the other tools are just crap !! I mean that: Why to generate code using just one package ? why to mix class and interfaces in the same package. This

Converting UML to OWL Ontology

阅读更多关于 Converting UML to OWL Ontology

问题 I am trying to develop an OWL ontology based on different UML file resources presented in xmi format. Reading through the internet for a while now, it seems that almost all the available tools or approaches are outdated and even when trying some of them they don't provide the expected outcome. Since this ontology plays a really important role in our project, i wanted to know what is the best approach/tools to be used in order to convert UML to OWL ? 回答1: I have looked into this myself as well

How do I draw an ESB on a SoaML diagram?

阅读更多关于 How do I draw an ESB on a SoaML diagram?

问题 I've recently had to draw some architectural diagrams that feature the use of an Enterprise Service Bus. The ESB is critical, so everyone wants it to show up on the diagram. But since it's the center of what everything is connected to, it really of gets in the way. I settled on trying to use SoaML. I color-coded the request points blue and service points green, to help then stand out. The text names on the ports give you a sense of what talks to what, and it's incredibly obvious that

设想和目标 1. 我们的软件要解决什么问题？是否定义得很清楚？是否对典型用户和典型场景有清晰的描述？我们的软件需要解决小微型个体户的进销存管理软件的使用问题。对于需要解决的问题有较为清楚的定义。但对用户和典型场景的描述不够清晰。 2. 我们达到目标了么（原计划的功能做到了几个？按照原计划交付时间交付了么？原计划达到的用户数量达到了么?) 达到了原计划的功能。交付时间稍晚于原计划。用户数量未达到原计划。 3. 有什么经验教训? 如果历史重来一遍, 我们会做什么改进? 在经验教训方面首先是时间安排，如果再来一次，会指定更加合理更易执行的时间安排。在设计方面，如果再来一次，会希望把更多时间放在设计上面，并且将设计文档做的更完善。计划 1. 是否有充足的时间来做计划? 有，虽然经过了团队成员的讨论，但是计划还是不够科学，低估了一些环节的困难，致使分配给这些环节的时间不够，从而导致后续环节也无法按计划进行。 2. 团队在计划阶段是如何解决同事们对于计划的不同意见的？通过商量解决，在平时的会议上提出异议并尽量在会上解决。 3. 你原计划的工作是否最后都做完了? 如果有没做完的，为什么?、还没，由于目前所涉及的静态资源较少，原计划要做的动静分离就并没有进行配置。 4. 有没有发现你做了一些事后看来没必要或没多大价值的事? 有，使用了第三方包来生成JSON。 5.
