Each edition (DK.NET, and DK-ActiveX, DK-CF, and DK-VCL) is tailored for a different development platform, and licensed as a separate product. The DK.NET, DK-ActiveX, and DK-VCL editions are available as a standard or Enterprise version. Enterprise versions include support for advanced spatial databases
For customers interested in GIS development using more than one DK edition, or desiring access to the DK-VCL source code just for "insurance" purposes, the DK-Combo 5 (or 10) developer license gives each developer rights to use the DK.NET, DK-ActiveX, and DK-VCL editon for a special price not much higher than the price of five licenses of a single DK edition. The DK-Combo licensing requires a minimum of five developer licenses.
