Corel Corporation developed and released a software program called CorelDRAW, a vector graphics editor. The software is more of a graphics suite than just a single, simple program, providing many features for users to edit graphics, including contrast adjustment, color balancing, adding special effects like borders to images, and it is capable of working with multiple layers and multiple pages.
CorelDraw was originally released in January of 1989, running on the Windows 2.x operating system. Today, the software is still used by many people, with the latest version, X6, being released on March 20, 2012. CorelDRAW is primarily designed for the Windows operating system, however, there were several releases for Mac OS and Mac OS X, but poor sales resulted in the discontinuation of those versions. There was also a port to Linux in 2000, requiring a modified version of Wine to run the software.
Corel Draw is a vector drawing tool. As such, it mainly used to create logos, signs and to vectorize images, or create new fonts (just in case you wondered how someone could build a brand new font from scratch, this is the type the program you would use, and in Corel Draw is very easy)yes, you can create your designs using Corel Draw (and slice and create the HTML, too, although I never suggest to use these tools in any program, and Corel Draw is not an exception).
It is a fantastic software but, as any other software, you need to know the interface. For some things, Corel Draw is better than Adobe Illustrator or Freehand (previously from Macromedia, now Adobe's since Macromedia has been bought by them). For other things, is harder to get the same result as in Illustrator.
Most of the people will tell you that Adobe's are better. Well, I use Adobe because I love Photoshop (I haven't seen any other software so powerful for photographs) and it's got a wider range of users. But, for certain tasks, I use Corel Draw, and I always say to myself "isn't this a great piece of software". It has nothing to envy to others. But it is a case of personal preference.
