How can I transform Entity-Based diagram to a JPA java code

阅读更多关于 How can I transform Entity-Based diagram to a JPA java code

问题 I have class diagram created with "Sparx Enterprise Architect v8.0" and i need to generate JPA-based classes with annotations that reflect relations to use it in the code. The problem is that i can convert it to EJB but not JPA which is required for my task. 回答1: I don't know this product, however they claim that it: supports modeling of database schema and automatic generation of DDL scripts for eleven DBMS targets out-of-the-box Once you have the database schema I believe there are various

问题 Model Driven Architecture is the idea that you create models which express the problem you need to solve in a way that is free of any (or at least most) implementation technologies, and then you generate implementation for one or more specific platforms. The claim is that working at a higher level of abstraction is far more powerful and productive. In addition, your models outlive technologies (so you still have something when your first language / platform becomes obsolete that you can use

Is model driven architecture worth it and what is the state of the art in the tooling?

问题 We have a recurring problem in our shop where we end up with 3 or 4 different representations of the same class/entity. A java version, an xml version, a hibernate version, a json version... you get the point. Obviously this creates maintenance problems. Model driven architecture is probably more than this, but what I'd really like is a system that lets me define a class or an entity once, in one way, and then generate various representations. (maybe I am not using the correct terminology for

Rational, EA, or something else?

阅读更多关于 Rational, EA, or something else?

问题 Does anyone have any thoughts on Rational Software Architect vs Sparx EA? Are there other tools I should be looking at? Specifically, I'm interested in the following; Adherance to some methodology (RUP, SOMF, etc.) -- we're not settled on one now, but need to pick one that suits a SoA architecture. Multi-modeling -- I need to model all the way from hardware (ideally with cost/spec tracking across physical and cloud) to deployment, classes/services, etc. Roundtrip -- reverse our code/data and

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 2 years ago . The Mythical Man-Month is now classic, but the "Surgical Team" methodology is still interesting. What methodology most closely resembles it or has the same essence? To summarize the Surgical Team analogy: A surgeon understands the problem/business domain and is the expert.

What is the differences between Traditional code-based engineering and model-driven engineering approaches?

阅读更多关于 What is the differences between Traditional code-based engineering and model-driven engineering approaches?

问题 I've found this paragraph in the literature but I didn't understand the meaning of it Design practice is moving from traditional code-based engineering, with a strong division of work along the development life cycle, to model-driven engineering approaches where all people in the design flow can have their saying on the models. Any help would be very appreciated 回答1: I am not sure that I agree with the way the sentence was written, but then I may be missing some context and, in any case, it

DisconnectedContext MDA when calling WMI functions in single-threaded application

阅读更多关于 DisconnectedContext MDA when calling WMI functions in single-threaded application

问题 I write an app in C#, .NET 3.0 in VS2005 with a feature of monitoring insertion/ejection of various removable drives (USB flash disks, CD-ROMs etc.). I did not want to use WMI, since it can be sometimes ambiguous (e.g. it can spawn multiple insertion events for a single USB drive), so I simply override the WndProc of my mainform to catch the WM_DEVICECHANGE message, as proposed here. Yesterday I run into a problem when it turned out that I will have to use WMI anyway to retrieve some obscure

问题 Microsoft, of Cairo fame, is working on Oslo, a new modeling platform. Bob Muglia, Senior Vice President of Microsoft Server & Tools Business, states that the benefits of modeling have always been clear. In simple, practical terms, what are the clear benefits that Oslo bestows upon its users? 回答1: In theory, there are a few benefits: The people with the business knowledge can create the software models so you're less likely to lose anything in translation.
