well no ias is NOT a database server, the concept of ias and oas are the same, they are both application servers with web server integrated, they are in same family, ias is oracle's new application server, it should be oas's next generation but ias has NOT inherited any oas architecture, it has been totally recoded. also oas's web server was not apache, I forgot the name but that one really sucked that's why they are using apache now

IAS is an Oracle database server and Apache web server integrated. It is a totally different product, with the similarity being they are both web servers.
