The name is Express, but has nothing to do with the old desupported OLAP-Tool from Oracle. This database is for free up to 4G of Userdata and one processor. I think less than 10% of the databases will need more than this. The installation was fine and worked without any troubles. The installation-file has just 150MB. And there are all features for what i like Oracle so much like PL/SQL, possibility to integrate Java in the database, WebSupport etc. . I will test it and post my results here.
