POUG Partnership

POUG is not only the official Oracle community – first of all it is the base of very active members, who are engaged in the group development both during the meetings and the preparations to them. Our message gets to the 400 people connected with databases – from the developers to the administrators and from the begginers to the experts with years of experience.

We would like to invite you to be a part of our event – it is a chance to show your brand during and before the meeting.
