    APEX is bunch of tables and PL/SQL. You need install APEX to database. Then you need also install ORDS for web listener.

    I hope this helps.

    BTW, if you plan install APEX 21.1, why you read version 5.1 documentation?

    Just to add some more detail. The client-server architecture for APEX is as follows:

    APEX is the application layer. However, it resides in the database tier and not in the mid tier. APEX is a PL./SQL application. As it runs in the database, the APEX app layer is very fast - there are no process, network or h/w boundaries for it to cross to access the data in the database. It scales with the database tier.

    The mid tier is the web server plus gateway to call the APEX runtime flow engine in the database. It can be standalone ORDS. It can be Apache Tomcat with ORDS. It can be WebLogic with ORDS.

    Then there is the client tier, the browser.

    Note that client-server is a s/w architecture. Not a h/w architecture. All 3 tiers can be on the same platform, e.g. your laptop.

    All 3 tiers can be on multiple platforms and can include multiple mid tier web servers, and a 30 server node database RAC cluster as database tier.
