My absolute favorite is Embarcadero ERSTudio. Fantastic set of functionality.

CA offers another that's extremely popular ERWin. There are a couple of others available, but those are the two big ones.

Embarcadero's ERStudio was a favourite of mine in the past.

I never really liked ERWin (even before CA bought it, and it's only gotten worse since then.) But some people swear by it.

I've been using Sybase PowerDesigner recently, and that seems to be okay.

For basic data modelling I use a white board and something like Visio. I already have Visio anyway, and I don't particularly need to do a lot of in-depth modelling. So you may want to consider just how much you need from your tool. If all you need to do is throw together some diagrams, then Visio may be enough.

I use NotepadWithPencil Version A4 and Brain Version 1.0 (I believe) to start. Sometimes MS Visio is quite handy, specially if you have an existing database and you want to get an overview about existing tables and relations (not always works). If it really needs to be professional I prefer PowerDesigner. Check this link: http://www.sybase.com/products/modelingdevelopment/powerdesigner

I have used both ERWin and Embarcadero ERStudio. I currently use ERStudio and I feel it offers a lot as compared to ERWin. One feature that i liked is it has a database capacity planning. I guess you can download a free trial of ERStudio and try for yourself a few days before you decide to buy.

I too have used ERStudio for years now. Good tool. It can get expensive, especially if you get cross-platform licenses. If you are sql server only they do (or used to) offer a much cheaper sql server only license.

Never having used a modelling tool, you may want to stick with visio though. ERStudio has a LOT of 'flexibility'. Smile

Heh. Nice to see someone who likes TOAD (I assume for SQL Server?) Personally I hate the product, but I know other people disagree. My issue with TOAD is that it tries to be a "jack of all trades" (and hence...) I have to admit I didn't even realise TOAD had a database design part, although it's been several years now since I had to use it, so it may have been a more recent addition.

I know a bunch of Oracle DBAs who are moving to SQL Server, and keep insisting that they need the SQL Server version of TOAD. I've been telling them to learn Management Studio instead. Perhaps I need to revisit that?

If I'm doing something small, paper or Visio work well. If I need to manage and handle changes to a larger database, I prefer ERStudio over Erwin. Haven't used TOAD.
