I have a class diagram , I want that to draw it in some tool which can generate native C++ out of it , I wish to have design first approach to test the various data structures I am designing for my application
A lot of tools can make C++ code out of UML diagrams. Try Software Ideas Modeller for example, it's a great UML tool, and it's free for non-commercial use.
Also, wiki has a list of UML tools. You can sort them by "languages generated" column to check what they do support and chose the one that you will like.
You can also try UMLET for your work.
You can seach mofre on google by typing

A project I am working on makes extensive use of CFCHART. We have run into quite a few usage and performance issues with CFCHART, so I have been tasked to look at some third-party solutions to try out and recommend. Anybody have some reviews and recommendations they'd care to share?
Consider outputting the raw data and using JavaScript / Canvas to generate the charts on the fly. The load is the given to the client.
This makes it easier for screenreaders and people who like to save the data to access it as well.
Some JS charting libraries:

http://omnipotent.net/jquery.sparkline/
http://code.google.com/p/flot/

http://www.highcharts.com/
Not dependent on your server side technology (e.g. irrelevant to the fact that you're using CF), I have recently started playing around with HighCharts (http://www.highcharts.com/), and have been very impressed.
Bear in mind, it's not free for commercial use, but you didn't specify as to any such restrictions. Although their pricing seems pretty fair (see http://www.highcharts.com/license)
The Wijmo jQuery library has some nice charting widgets. http://wijmo.com/
We use FusionCharts. They have a comprehensive set of chart and widget types (eg sparklines) and have a very slick, professional finish.
ChartDirector is reasonable and is very advanced. It generates image-based graphs and we don't have to worry about whether or not different browsers support various advanced HTML features or Flash. You can download it, install and run it unlicensed and it will only add a little copyright in the bottom-right 20 pixels of the graph. (Licensing is inexpensive.) It comes with 239+ ColdFusion scripts so that you have plenty of sample code. Their support forums is very active and helpful.

Check out the gallery. It has some very impressive samples. You can create just about anything.

You can try jqChart as well.
Thank you to everyone for these suggestions! This gives me a good list of applications to work with. Since there is no one "right" answer for a question like this I made sure to note each answer as useful.
I was looking at MeVisLab and I wondered if anyone knows a good framework for making a user interface similar to the one they use. I like the designing flow with boxes and arrows thing.
What I would really like is to able to integrate with C++ using Qt, and perhaps export the graph to xml of something like that.
There is another example of the interface here:
I hope someone knows something
Qt's Graphics View is a "framework" which does a good bit of the handling for the kind of scenario you describe. It doesn't take much code to get off the ground and within striking range of what you're looking for:
http://doc.qt.nokia.com/latest/graphicsview-diagramscene.html
http://doc.qt.nokia.com/latest/graphicsview-elasticnodes.html
I'm not aware of any open-source Qt-based programs that offer exactly what you want already written. Just noticed IBM did open source "DataExplorer", which is interesting to me...I might go take a look at that myself:
http://www.research.ibm.com/dx/
Could some one point to articles / books on how to create good flow chart diagrams?
BoUML-it's free!
I've used this open source tool for the last 6 months at work to create UML diagrams:
bouml.free.fr/
I've used it on both a Macbook running OS X, as well as Ubuntu Linux on a desktop, both with success. It also does codegen (although I haven't used this feature myself). If you create a diagram from within BoUML, you can right click ->Tools->HTML etc,etc., and it and actually generate the diagram -- this will create a whole tree of html, css, etc., and include a .png file which you can later choose to import into a Word-like document.
If you're new to UML, and would like to explore that route, I suggest UML Distilled by Martin Fowler as a way to quickly ramp up. I still use this as a reference when I'm putting diagrams together and I forget some syntactical detail ;) The nice thing about UML is that most programmers will understand it. If you don't want to buy a book you can, of course, Google 'UML tutorial' and get a slew of free info.
Non-UML:
You can also use open office's draw application to do some simple flow charting. It has some nice non-uml shapes, so if you're not trying to be 'strict' in the sense of conforming to UML, and just want a simple flow chart, that may be a good choice.

One of the first things I do when I'm on a new project is design a database model. To visualize the model I use a 7 year old version of Smartdraw. Maybe it's time for something new. What is the ultimate program to make a drawing of a database model. Smartdraw is for Windows only. Is there something that can be used on unix as well?
The best tool is pencil and paper.
Perhaps not the answer you are looking for, but sometimes the most simple solution is the best. :-)
A whiteboard (and camera to take a picture afterwards)
Your brain is the best drawing tool.
I prefer to develop a database schema in a simple text file.
At first it contains just the table names, attributes and foreign keys:
company:
company_name
...
employee:
name
age
company_name -> company
...
...:
The syntax is not important.
It just needs to be clearly arranged and easy to change.
Later I add types and CHECK() constraints,
so the text file gradually transforms into valid SQL code.
Using a drawing tool in that early stage is just distracting,
because it encourages to waste your time with moving reactangles.
Instead, let your brain build a picture of the schema
in the same way it creates fantasy pictures while reading a book.
As the schema grows,
it becomes necessary to support the brain by creating an overview.
Here, however, pencil and paper are faster than any drawing software.
Also note that there is no need to clutter an overview with unimportant details.
Just sketch the table names and the most important relationships (foreign keys).
Any further details will decrease the value of this overview.
However, if you really feel more comfortable with extremely detailed graphics than with text files and overview graphics, you might want to try
DBDesigner4
or
WWW SQL Designer.
I'm happy using Sybase PowerDesigner for years now.
Did you take a look at Visio 2007 SQL Server Add-In?
You can find it here: http://dbalink.wordpress.com/2008/04/24/microsoft-office-visio-2007-professional-sql-server-add-in/
WWW SQL Designer is one of the best that I've seen, which is pretty amazing since it is all javascript. It can also import and export xml and sql code of everything you draw. And they've added nifty bezier curves since I last used it.
I don't know if it's the "ultimate" program for drawing database models, but I use Visio. Unfortunately, it only runs in Windows.
On the upside, I can create my own shapes, or modify existing ones, and save them in collections called stencils. I can also make my shapes "smart" by programming them to do various things when I double click on them.
I use a whiteboard and a camera as well. I second the pencil and paper. I keep a pen(cil) and pad of paper with me almost always because I am forever designing something in my head and need to jot it down. I like Visio as well but my favorite software program to use has always been ERWin. The price of that thing is just way out line, but it is great.
I like ERWin. Not Cheap, but it can reverse engineer or do initial design + generate CRUD and manipulate db structure. Viso is pretty good for this too, but its not as complete and of course as strong MS SQL leanings is capabilities.
I used to use Visio, but if your database server is MySQL, try MySQL Workbench. It has a linux version as well as a win32 version. Like their other GUI products it has its fair share of quirks, but it works quite well and has the ability to create a diagram of a schema and a schema from a diagram.
I also agree that a pencil and paper, or whiteboard and camera is a great way to sketch things out, but I do like the GUI tools for putting down an idea which is a bit more well formed or complicated.
I like to use the open-source mind-mapping program Freemind. It's similar to designing with pencil and paper in that there's not a lot of surface complexity to interrupt the design process.
But it has two huge advantages over paper/pencil:
node folding
easy drag-and-drop re-arranging
It is very easy to navigate the interface without using the mouse within about five minutes. You can add as many or as few details as you like and can always fold up the details to de-clutter your view. Here's a sample screenshot:
The circles at the ends of the Departments, Employees, and Hours tables indicate that there are more nodes that are folded up. You can go crazy with different fonts, background colors, and even HTML formatting. I just did a [Ctrl]-[B] to make my table names Bold.
FreeMind--and mind-mapping software in general--provides its biggest benefit by staying out of the way of the creative process. It's the first tool I turn to when starting a new project from scratch.
NOTE: I've only ever used the program on Windows, but it is available on Linux.
DIA is not bad, and there are tools to actually generate some code from some types of models. If you are using PostgreSQL, there is even a tool for going the other way, pg-autodoc.
DIA is available for Unix, and I believe Windows as well.
I used to use Viso but now, as I'm more Mac based I use Omnigraffle.
I do have to admit though, as andyUK does, I do a rough sketch on paper.
It also depends on what Database you're using. If it's MySQL then there are quite a few visual development tools available, just have a google
There may be more technical programs, but I use SmartDraw. I would also like to note that 'ultimate' is up to your circumstances. Find what works best for you or you and your company. What works for you is the 'ultimate'.
Brainstorm/sketch the database on paper/whiteboard first, and then go with a diagram tool.
Which tool depends on your target database. We use SQL Server and thus the designer in SQL Server Management Studio works great for us, since we create the database itself at the same time.
For linux I use umbrello
If you're looking for a cheap solution/tool without any reverse/forward engineering capabilities, MS Visio might be your best bet. However, if you're planning to invest some money toward ERD tool, spend it on ER/Studio.
I used to use and be champion of ERWIN. As soon as I started to use ER/Studio, I became fan of it. I'm an enterprise data architect at one of the Fortune 100 company and I don't know how to get my work done without it.
PS: I don't have no affiliations with any of those products and companies.
OpenOffice has a vector drawing tool, and Inkscape is a another good one.
Otherwise, you can use Graphviz (dot language) to generate such diagram out of a textual description.
There are also some tools to generate such diagram out of an existing database (I first thought it was what you were asking).
If you don't need much take Dia.
I used Power Designer. It's powerful but rather complex.
