In this article We will look into that what is the Oracle apex, Why it used for web application development, How its works and its advantages.
What is Oracle Apex :
Oracle apex is a web application tool for Oracle database. It is used to create
responsive web application quick and secure.
You can ask who will be suitable person for these kind of application development process. I would say that who having a minimum programming knowledge on web development and good knowledge on SQL and PL SQL are suitable person.
It's inbuilt component make development very quicker and it provide many type of pages to simplify the creation page such as Report, Form, Chart , Calendar, Feedback page,Tree page and etc.
As said above with minimum program knowledge and SQL
knowledge user also can develop and deploy the application.
Another advantage is It doesn't require
any IDE or software for create web application, Through web browser itself
we can create an application.
Advantage :
- It is simple, fast and secure development.
- It uses a Browser to develop an application.
- It provide inbuilt component such as report, form, chart, Tree and etc.
- It provide packaged applications to learn how to application implemented an application. This will use for beginner as well as experienced who looking a quick solution for their business needs.

How it works?
Oracle Application Express installs
with your Oracle database and consists of data in tables and PL/SQL
code. Whether you run the Oracle Application Express development
environment or run an application built using Oracle Application
Express, the process is the same. Your browser sends a URL request
that is translated into the appropriate Oracle Application Express
PL/SQL call. After the database processes the PL/SQL, the results are
relayed back to your browser as HTML. This cycle happens each time
you either request or submit a page.
In other words, We are developing
application using browser so every process will happening through URL
only. So whenever application start to run then the URL converted as
appropriate PL SQL call to reach oracle database. After finished
necessary process in the database it come back as html result in
browser. This happening every time we requesting or submitting a
page.
