Introduction
 Oracle Apex: Oracle Application Express is a rapid
Web application development tool that lets you share
data and create applications. Using only a Web
browser and limited programming experience, you can
develop and deploy applications that are fast and
secure.
 APEX is a 100% browser-based rapid application
development (RAD) tool that helps you to create rich
interactive interactive Oracle-based web applications
very quickly and with relatively little programming
effort.

Advantages of Oracle APEX
 Fast growing technology
 Web-based
 Developers familiar with PL/SQL can use the same skill set when developing
Apex applications
 Easy to create mock-ups
 Easy to deploy (end user opens a URL to access an APEX application)
 Scalable (can be deployed to laptops, stand-alone servers, or Oracle RAC
installations)
 Server-side processing and validations
 Strong and supportive user community (especially Oracle APEX forum)
 Basic support for group development
 Free hosting of demo applications provided by Oracle
 Apex applications can run on the free Oracle Express Edition (XE) database
 Individual components of an application can be retrieved or identified using
SQL

History

Architecture
 Oracle Application Express consists of
--A metadata repository that stores the definitions of applications and
--An engine (called the Application Express engine) that renders and
processes pages.
 It lives completely within your Oracle database.
It is comprised of nothing more than data in tables and large amounts
of PL/SQL code.
The essence of Oracle Application Express is approximately 425 tables
and 230 PL/SQL packages containing 425,000+ lines of code.

Browser Based application development

APEX hierarchical menu structure

Application Builder
The Application Builder is where you create and modify
applications and pages, and it’s where you’ll probably
spend most of your time.
 Centerpiece of APEX
 Loaded with wizards
 Reports, forms and charts
 Connect pages using branches
 75 pre-defined widgets
 Basic HTML, pop-up lists, calendars, etc.
 Full data entry validation

SQL Workshop
The SQL Workshop is where you deal directly with the
underlying database objects and their related data. Think of
it as a web-based version of SQL*PLUS with some GUI
goodness thrown in to make things easier.
 - Object Browser to review and maintain DB Objects
 - SQL Commands to run SQL
 - SQL Scripts to upload and execute script files
- Utilities include Query Builder, Data Workshop, Generate
DDL, Schema Comparison and more
- RESTful Services to define Web Services using SQL and
PL/SQL against the database

Team Development
 Team Development is the section that lets you enter and
track information related to the development of APEX
applications.
 Team Development allows development teams to better
manage their APEX projects by defining milestones,
features, to-dos and bugs
 Features, to-dos and bugs can be associated with specific
applications and pages as necessary
 Developers can readily configure feedback to allow their
end-users to provide comments on applications.
 The feedback also captures relevant session state details
and can be readily converted to a feature, to-do or bug.

Administrator
 Workspace Administrators can administer their
workspace and use the various reports to monitor
activity
 Manage Service allows them to request more space or
access to another schema
 Manage Users and Groups allows them to define
developers and end-users

Mobile Support
 Declarative support for building mobile web applications
 APEX Applications support multiple user interfaces:
e.g. Desktop and Smartphone
 Mobile pages use jQuery Mobile through
jQuery Mobile based themes and templates
 HTML5 charts and new HTML5 item types
 By using APEX we can develop Web as well as
Hybrid Applications in Android , iOS and Windows .

Demo Application
 Scenario:
we want to make a web application of “Help Desk” using
Oracle APEX.

Database Design
 We have to make 2 tables:
1.Ticket
2. Ticket Details.

Navigate to the Object Browser
1. Log into your APEX workspace. You’re presented with the
workspace’s Home page.
2. Using the tabbed navigation bar across the top of the
Home page, pull down the
SQL Workshop submenu by clicking the arrow on the right
side of the tab.

Defining the tables and column
3. Click the Object Browser option.
4. In the Object Browser, click the Create button in the upper-
right corner and select Table from the drop-down menu.
5.Enter the details for the TICKETS table. Then click Next.

Defining the table’s primary key
6. Select the Populated from a new sequence radio button. After the screen
changes, select TICKET_ID (NUMBER) for the primary key. Click Next.
7. You’re not going to create any foreign keys in this table just yet, so leave the
defaults and click Next.

The Constraints definition step
8. We’re not going to create any Unique or Check
constraints here, so stick with the defaults and click
Next.

Review the Create Table Wizard’s SQL
 Review the text in the SQL region presented by the Create
Table Wizard. Click Create Table to complete the
wizard.

TICKET_DETAILS(only screenshots)
 Now follow the same steps for TICKET_DETAILS
table.

Loading Data with the Data Workshop Utility
1. Go to SQL Workshop->Utilities->Data Workshop

Preparing to copy and paste the spreadsheet data and
load it into the existing TICKETS table
1.Locate the helpdesk_spreadsheet.xls file where you downloaded the supporting files for
this book, and open it with Microsoft Excel. Navigate to the TICKETS tab. Notice that you
have a row for each ticket and a header row that contains the column headings for each of
the columns.
2. Select all the data, including the column headings, and copy it to the clipboard. Be
cautious not to accidentally select any rows that don’t have data in them, because that may
cause phantom rows or errors in the Data Load Wizard.
3. Switch back to your web browser, and, using the pull-down menu on the SQL Workshop
tab, select Data Workshop.
4. In the Data Load region, click Spreadsheet Data. You should see the Load Data
dialog
shown in Figure

Cont..
5. In the wizard, select Existing table for Load To and Copy
and paste for Load From, and click Next.
6. Select your “parse as” Schema from the Schema select
list. This is the same schema in which you created your
tables in the Object Browser.
7. Select TICKETS for the Table Name, as shown in
Figure, and click Next. This is the table into which you’ll
load the TICKETS data.

Pasting the spreadsheet data into the
Data text box
8. Paste the data that you copied to the clipboard in step 2 into the
Data text area, and ensure that First row contains column
names box is checked, as shown in Figure. Click Next.
9. When you’re sure all the mappings are correct, click the Load
Data button to load the data into the TICKETS table.

Preparing to copy and paste the spreadsheet data and
load it into the existing TICKETS table
 Follow the previous steps and load data into
TICKETS_DETAILS table..

Creating a Lookup Table
1. Navigate to the Object Browser, and select the TICKETS
table in the Object List on the left side of the screen.
You should see results similar to those shown in Figure

Clicking the Create Lookup Table button
starts the Create Lookup Table Wizard
2. Make sure the Table tab is selected.
3. Below the tab bar is a set of button-like links. Click the
Create Lookup Table button, as shown by the mouse
arrow in Figure; it starts the Create Lookup Table Wizard.

Selecting the STATUS column as the source of your
lookup table
4. Select STATUS as the column from which you want to create the lookup table, and
click Next.
5. On this screen you can name your lookup table and the sequence that is related to it.
APEX
has chosen a reasonable name for the new table and sequence, so take the defaults and
click Next.
6. The final screen of the wizard provides you with information about the
choices made and the action that is about to be performed. It’s easy to miss the SQL syntax
link just below the wizard region. Click the SQL link to show the SQL.

Clicking the SQL syntax link shows the SQL
about to be executed
6. The final screen of the wizard (Figure 4-18) provides you
with information about the choices made and the action
that is about to be performed. It’s easy to miss the SQL
syntax link just below the wizard region. Click the SQL
link to show the SQL.
