open software sluit zich
In MySQL's case, the Swedish company uses the General Public License (GPL) to cover its database software and the supporting libraries that other programs use to interface with the database. Previously, though, the libraries were covered by the Lesser General Public License (LGPL).
An essential difference between the two licenses is that proprietary or other non-GPL software may be tightly linked to LGPL software.
Dus op 1 ogenblik heb je het recht om je software te integeren met mysql en dan in de update, mag het niet meer in open gratis licence maar moet je betalen......
