Pract-Eze Source License

What is Pract-Eze Source software?
It means that the source code, the original text of the program, is available for anyone to download. Any programmer with a moderate level of skill can turn this source code into a fully functional version of the program. Pract-Eze Dental is licensed under the GNU General Public License (GPL), the standard open source license. This license ensures that the software will always remain free and nobody can take away your freedom to use it. Pract-Eze Dental is Copyrighted by Dr Jordan Sparks to prevent anyone from turning it into a proprietary system. Anyone is free to copy, distribute, and change the software, or to do whatever they want with it and they don't have to tell anyone as long as the copyright notice and license remains attached.

How much does it cost ?
The GPL license does permit and encourage charging for distribution and support. See the support and fees section for prices. But, as with all truly free software, users don't actually have to pay the distribution fee or support fee in order to use the software. You could just make a free copy from a friend and be completely within your rights. You can also have an unlimited number of copies running on computers at your office without any licensing restrictions or dongles (hardware-enforced limits on the number of copies of a program).

Why is it so inexpensive ?
Fundamentally, it is because it doesn't cost us anything when other people use it. The distribution fee covers our costs and any support we provide is paid for separately. The question you really need to ask is, "Why is other dental software so expensive?" Two factors that have driven our costs down are the powerful open source MySQL database, and the very efficient C# programming language which lets us produce more features in less time.

Why is it open source?
Because we want this software to become the world standard dental software. We want to make it easy to access and share data. We are tired of the restrictive policies of the current dental software companies. We want the user to always have total control, not the software company. And most of all, we want software that just works well.

What if you go out of business?
If we go out of business, the situation would be very different than with any other dental software. Since anyone has the freedom to develop and support Pract-Eze Dental, and since there is already a large existing customer base, there will always be plenty of incentive for various companies to build on what we started. But, of course, we don't plan on going anywhere. We see it as a resource for the dental community that can never be taken away from us. Since it cannot be bought out, it will always continue to grow and benefit everyone.

What is the advantage of having an open database?
The structure of the data is available for all to see and use (the data is still very secure). It is totally different than the proprietary format that all other dental software uses. Other programs can only export certain fields. In Pract-Eze Dental, you have access to and control over every single bit of data. Your data will never need to be converted again.

What restrictions does the free license impose?
If you don't modify the program, there are no restrictions whatsoever. If you are a programmer, you can look in the Developer's section for details on exactly what is allowed. Basically, any modified versions of Pract-Eze Dental must also be made available as free software under the GPL.

Who is doing all this work?
Dr. Jordan Sparks has done most of the programming. He has done the many thousands of hours of programming in his spare time over the last few years. But since the software is now becoming so popular, he is beginning to cut back on dentistry to devote more of his time to programming. You can expect the pace of new features to only increase as time goes by.
