Oracle Application Express (Apex) is a great tool for DBAs to quicky bang up a web application based around an Oracle database and using PL/SQL. One of the limitations  in a multi-vendor database environment is it doesn't play well with other databases.

There are workarounds - such as taking feeds or exporting feeds , and then using Apex to report.

I've been looking at a few alternatives to Oracle Apex. I know that some people will come back with Ruby on Rails - but thinking  other options.

A few I've looked at recently. If you have been working with alternatives to Oracle Apex and would recommend using - either Contact me or leave a comment below
