Architecture
Multi-Tenancy
ORACLE APEX ENGINE
APEX lives and breathes inside the Database

Architecture
1) Embedded PL/SQL Gateway(EPG)
2) Oracle HTTP Server-Apache(mod_plsql)
Deprecated Of 12c-12.1.3+
3) ORDS (Standard , Advanced)
Oracle REST Data Services
Installation
4) ORDS (Standalone Mode)
Built-in Jetty web server

Architecture
Web Listener comparison

Architecture
Web development approaches
• Two Basic:
• Code based approaches like Java, .NET and JavaScript frameworks
 Have to code the User Interface (UI) and the Controller logic (what happens when you click a button, a link, submit
a page, etc.)
 This requires knowing Java , .NET or JavaScript very well as a start. After that you have to deal with often very
complex APIs. These APIs are like a separate language.
 Have to code approximately 4000 lines for single page. The customers want custom adjustments to the UI and
functionality, so this can cause problems.
• Component-based code generators like QlikView
 With this approach you don’t really code anything, you just drag and drop ready-to-use front-end components in
your development tool, When you click finish, the corresponding code and logic are generated for you
 Also very little influence of the User Interface. Even the logic is more or less predefined

Architecture
Web development approaches
• Customer Needs:
 Always want individual changes in the User Interface and for the logic
 These small changes are the difference between a customer loving and identifying with the application
and a customer resigning themselves to a given User Experience (UX)
• As Result:
 The software should also be
Fast to develop
Easy to change

Technologies to learn
The basic level of understanding for the Oracle Database
What’s a User? A Schema? A Workspace?
When do you use SQL? When do you use PL/SQL?
How do SQL and PL/SQL work?
What are Tables, Views, and Indexes?

To understand the basic principles of Web development
How does a browser work?
What’s the DOM? What does it do? How can you manipulate it?
Where can you use JavaScript and when do you need it?
How do you deal with CSS?
What is a POST and what is a GET in HTTP?
What’s a Web server good for?
How does a Request go from the Browser to the Web server to the Database and back, the so called roundtrip?

Learn the basic principles of the Oracle
Database, SQL, and PL/SQL.
After that you are at 60%. By the way, you
are now an Oracle Developer! You can
program this very famous Database and
develop business logic in the backend
without APEX too.
First Step

The next step is to learn the front-end
technologies: HTML, CSS, and JavaScript.
This is also totally independent from APEX. You need
this knowledge for every Web development. You can go
a very long way without knowing these languages in
APEX. You can manipulate your User Interface any way
you'd like and it's just a lot of fun. After that you are at
80%.
Second Step

The final step is to learn jQuery and
Dynamic Actions.
jQuery is a JavaScript Framework and very popular
and used in more than 50% of all Web sites.
Dynamic Actions is the declarative layer on top of
jQuery to achieve interactive AJAX calls and UI
manipulations. Once you've done all this, you have
reached 100%
Third Step

How long will it take
Let’s say you start at 0%
You have no idea of programming, databases, or Web
development.
If you can invest just two hours every day and you are
serious about it, you should achieve the 100% within a year!
You can use this knowledge in all related database
and Web development approaches

How to learn Oracle APEX
Use Cloud https://apex.oracle.com/
APEX is Cloud-based
All you need to develop, administrate,
and test an APEX application is a Browser.
So go to apex.oracle.com and get
yourself a free Workspace
(a small part of a Database).
You should be up and running in five minutes.

Books, Videos, Webinars
There are books out there, Video Trainings and
Live Webinars with teachers you can talk to,
or the official Oracle training with onsite classes.
Also Classes available in a wide variety of
countries and languages.
