Dear all;

I would like to order the 180 single user pl/sql product, however, how long is the license valid for becuase I didnt see any expiration date for that in the product session.

Furthermore, is the installation going to be easy and smooth for a home edition windows 7 OS.

A PL/SQL Developer license is a perpetual license, so it will never be invalidated. Only the Annual Service Contract would require yearly renewal if you need its services (upgrades, technical support).

Installation is very easy. Just run setup and accept all defaults.
