What is DataLicense?

DataLicense is a collection of 4th Dimension® methods and forms that provide piracy protection for your work. DataLicense uses no plug-ins. All code is native 4th Dimension so the developer may customize any aspect of it, and it will run without conflict on any platform that 4th Dimension will.

DataLicense does not license a datafile for distribution!
It protects your structure from piracy and it uses your clients' datafile to do it.. Even a newly created datafile.

DataLicense has several advantages over plug-ins that require your customers to enter a serial number to use your 4D programs.

• Instead of serializing the structure, DataLicense serializes the datafile. If the structure is serialized, there is nothing to prevent software pirates from distributing the serial number with the application. Since DataLicense builds it's serial numbers from an encryption of the user's business name, when a pirate enters his own business name the serial number is not valid and the program will ask for a number the next time it is restarted. To be most effective, the user's business name should appear on important print layouts such as invoices, purchase orders, schedules, etc., and can also be used as the window title of the home or splash screen.
• Every new datafile is a time-limited TRIAL datafile. The developer may set a number of days that a new datafile will work before a serial number is requested. This is handy if you are offering limited-time tryouts, or if you're working for a client without having been paid in full.
• If a prospect needs more evaluation time, or the custom project is still unpaid at the end of the trial period you may issue a temporary extension to a specific future date.
• If a pirate uses your software free for a period of time, by the time a serial number is required they will (hopefully) be dependent on your software and its datafile. DataLicense makes sure they have your phone number!
• You may tag a datafile as a "Demo" datafile and it will run forever (with whatever limitations you program in). DataLicense provides a mechanism to allow the user to convert the datafile to a real one (with or without a subsequent trial period.)
• DataLicense allows the developer to limit the number of users who may have concurrent access. You can eliminate the possibility that a customer will buy Server expansion packs from someone else and not pay you for larger installations.
• DataLicense will register up to 32 optional modules.
• Each of your applications will recognize different serial numbers. Serial numbers from one of your apps will not register any other.
• The included Generator standalone application will read registration files sent from your DataLicense-enabled applications, generate serial numbers and send files which automatically serialize your application, and maintain records on your clients' and customers' registrations.

With DataLicense installed, any of your 4D programs may be freely distributed without fear of piracy.

With DataLicense installed, you can work on custom solutions knowing that if the client does not pay they will not be able to use your software.

In the event you are not paid and the trial period expires, DataLicense will offer to export the client's data to disk. This prevents a cantankerous deadbeat from making the legal claim that you prevented them from accessing their data.

What's Included?

DataLicense includes all methods and forms to make the system work in any 4D structure, plus a User Guide PDF. Everything may be installed with one drag from a 4D Insider file, and customization is easy.

A separate compiled 4D application (itself protected with DataLicense) that generates serial numbers is included.

Now that you've given away your ideas, can't I write this myself?

Sure, if you know 4D well, but how much is your time worth?

Also, as you'll see when you read the code, we've thought of a few things that probably haven't occurred to you.
