4. Main benefits of APEX
It’s free to use
If you have an Oracle database, then you already own APEX. Using it won’t
cost you anything.
It’s easy to get started
There are no complex programs to install on your machine before you get
started. All you need is a web browser.
You don’t need to be a “coder”
With its easy-to-use interface, you can build amazing applications without
writing any code.
One of the greatest advantages of Oracle APEX is that you have native
access to all the capabilities of Oracle Database.

11. Where can you run Oracle APEX
https://www.oracleapextrainer.com/
Oracle Cloud:
You can run APEX in an Autonomous Database (ADB) – an elastic database
that you can scale up. It’s self-driving, self-healing, and can repair and upgrade
itself. It comes in two flavours:
• Autonomous Transaction Processing (ATP) – basically transaction
processing, it’s where APEX sees most use;
• Autonomous Data Warehouse (ADW) – for more query-driven APEX
applications. Reporting data is also a common use of Oracle APEX.
You can also use the new Database Cloud Service (DCS) – an APEX-only
solution. For a fee, you can have a commercial application running on a
database cloud service
12. Where can you run Oracle APEX
https://www.oracleapextrainer.com/
On-premise or Private Cloud
You can also run Oracle APEX on-premise or in a Private Cloud – anywhere
where a database runs. It can be a physical, dedicated server, a virtualized
machine, a docker image (you can run it on your laptop, fire it up on a train or a
plane – it’s very popular among Oracle Application Express developers).
You can also use it on Exadata – a super-powerful APEX physical server on
cloud services.
14. Architectural Overview
Oracle APEX uses a simple 3-tier architecture where requests are sent
from the browser, through a web server, to the database.
All processing, data manipulation and business logic is executed in the
database. This architecture guarantees zero latency data access, top
performance, and scalability, out of the box.

16. What is ORDS ?
https://www.oracleapextrainer.com/
ORDS (formerly known as Oracle Application Express Listener) is a
middle tier JAVA application that allows to access Oracle Database
resources via REST. Use standard HTTP calls
(GET|POST|PUT|DELETE|HEAD) via URIs that ORDS makes available.

19. The APEX Advantages
https://www.oracleapextrainer.com/
Cost
There are no licensing costs associated with Oracle APEX. Oracle APEX is a
feature of Oracle Database, thus if you have a license for Oracle Database,
you already have Oracle APEX.
Flexibility
With Oracle APEX you have a lot of flexibility with where you do development,
from developing on a laptop, on-premises, or in the cloud. Where you develop
your apps doesn't limit where you can deploy your applications. You can
develop and deploy wherever there is an Oracle Database, with Oracle APEX
installed. No need to install any desktop client for application development. Just
need web browser for everything.
20. The APEX Advantages
https://www.oracleapextrainer.com/
Reuse
All of the underlying database programs (packages, functions, procedures)
can very easily be called directly from Oracle APEX. Therefore, you do not to
rewrite the extensive database business logic you are already utilizing from
Oracle Forms.
Improved User Experience
APEX application can streamline the specific use cases, making them fully
responsive and mobile friendly. Frequently one APEX interactive report can
replace many forms page.
Multiple Technologies
In APEX multiple web technologies like HTML, JavaScript, CSS, Jquery etc.
can be easily integrated which makes end user experience better.
