I just use SQL Server using the diagrams folder. The designer is pretty simple to use, and can be used to generate tables fairly quickly. Considering it's free with the software, I don't see the issue.

blocks|key|2977510|text|Power*Architect是最好的选择。它是免费的，开源的，非常好的帮助你构建你的ERD。此外，它还可以在Windows、Linux和OSX上运行。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2977511|entityMap|0|LINK|mutability|MUTABLE|url|http://www.sqlpower.ca/page/architect^0|0|F|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

<a href="http://www.sqlpower.ca/page/architect" rel="noreferrer">Power*Architect</a> is the way to go. It's free, open source, and does a really great job helping you build your ERDs. Plus, it works on Windows, Linux, and OSX.

blocks|key|2977862|text|那MagicDraw呢？这是一个非常强大的工具，但我认为它和PowerDesigner一样昂贵，我不确定。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2977863|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

How about MagicDraw? It is a very powerfull tool, but I think it as expensive as PowerDesigner, not sure.

blocks|key|5231778|text|你可能想看看https://www.xcase.com/demo.php。它不是免费的，但据我所知，它比PowerDesigner便宜得多。我使用过早期的版本，但最近我可以很容易地使用Visio，所以我继续使用它，而不是投资于xCase。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5231779|entityMap|0|LINK|mutability|MUTABLE|url|https://www.xcase.com/demo.php^0|6|U|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

You might want to look at <a href="https://www.xcase.com/demo.php" rel="nofollow noreferrer">https://www.xcase.com/demo.php</a>. It's not free, but it's quite a bit cheaper than PowerDesigner, as far as I can tell. I've used earlier versions, but lately I've had easy access to Visio, so have continued with that instead of investing in xCase.

blocks|key|5231849|text|VS+Enterprise+Architect附带的Visio版本具有可生成SQL的前向工程功能。还有一个用于建模引擎的类型库，但(至少在旧版本中)它不会提取某些项，如注释。但是，生成的SQL具有相当简单的结构中的注释，这确实有助于解析生成的SQL。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5231850|你可以在E-bay上获得VS+enterprise+architect的旧版本，花费不是很多(我想我的成本大约是250£)。|5231851|逆向工程师需要注意的一点是，所有VS2005之前版本的visio+DB建模引擎都不能很好地与SQL+Server+2005本机客户端配合使用。您需要编写数据库脚本并将其重新加载到SQL2000服务器上(模式等特定于SQL2005的特性的处理留给读者作为练习)，或者获取更新的版本。|5231852|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

The version of Visio that comes with VS Enterprise Architect has a forward-engineer feature that will generate SQL. There is also a type library for the modelling engine, but (on older versions at least) it won't extract certain items such as comments. However, the generated SQL has the comments in a fairly simple structure that does facilitate parsing the generated SQL.

You can get older versions of VS enterprise architect on E-bay for not very much money (I think mine cost about £250).

One caveat for reverse-engineers is that all pre-VS2005 visio DB modelling engines will not play nicely with the SQL Server 2005 native client. You need to either script out the database and re-load it on a SQL2000 server (dealing with SQL2005 specific features such as schemas is left as an exercise for the reader) or get a more recent version.

blocks|key|3821583|text|好吧，还有另一种选择。使用它不仅仅是制作表格！利用它，让你的钱物有所值。你已经付钱了，你可以放弃维护，按原样使用它。无论如何，一些值得深思的事情。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3821584|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Well there's another alternative. Use it for more than just making tables! Exploit it, get your money's worth. You've already paid for it, you could drop the maintenance and just use it as-is. Anyways, something to ponder.

We are using PowerDesigner at work for database modelling. But there is a hell of a price tag on that piece of software. And frankly, all I use is physical diagrams for MS SQL, which is about 1% of what PD knows.

Are there any good alternatives? I know about Visio and MS SQL Diagrams, but looking for other options.

Free/cheap PowerDesigner alternative?

我们在工作中使用PowerDesigner进行数据库建模。但这款软件的价格实在是高得离谱。坦率地说，我使用的都是MS SQL的物理图，大约是PD所知道的1%。有什么好的选择吗？我知道Visio和MS SQL图表，但正在寻找其他选项。
