IntroductionOracle Application Express


Oracle Application Express

• Database-centric development tool for Oracle Database application development• Targeted at Web-based developers who know SQL and PL/SQL• Develop Desktop and Mobile applications• 100% Browser-based Development and Runtime• Declarative framework for rapid application definition, and full application life cycle. • On premise, on laptop, on cloud, on RAC, any platform Oracle DB is available

Architecture

• Mid tier = Oracle REST Data Services• Directs calls to APEX Apps to the APEX run-time engine

• Accepts RESTful Web Service call URIs and directs them to the appropriate SQL statement or PL/SQL block

• Recommended mid tier for Oracle APEX.

• Can also use Embedded PL/SQL Gateway (EPG) and Oracle HTTP Server (OHS).

• Application Meta Data stored in the Oracle DB• Oracle Application Express is written largely in PL/SQL• Pages dynamically rendered using database metadata

• No code generation or file based compilation

(Proxies client requests to APEX engine in DB)

Simple 2-Tier Architecture

Pseudo Demo Flow: Building and deploying an Application



1. Initiate Create App Wizard 2. Add Pages

3. Confirm and Create 4. Run the Application

Create a report and form on a table

Building ApplicationsApplication Builder Build Application Wizard


1. From Runtime click ‘Edit Page x’ 2. Select page component

3. Edit component, click ‘Apply Changes’ 4. Click ‘Run’ to view changes

Building Applications – Editing an ApplicationIterate from Runtime Development Runtime Repeat


1. Export Application 2. Export generates a SQL Script

3. Provide File to DBA

4. DBA Runs Script in Production

Extending Oracle E-Business Suite Release 12 using Oracle Application Express



• Outlines best practices for developing fully supported E-Business Suite R12 Extensions

• Provides certified / supported architecture• Includes detailed steps for configuration,

integration and security• Downloadable sample application and code• Collaboration between Oracle E-Business Suite

and Oracle Application Express development teams

• Custom Application Development Real time queries on EBS, with option to update EBS data using APIs Deliver net new business functionality (not covered by EBS) Additional reporting and analysis Custom data collection / workflows Personalization of complex EBS workflows Modernization of custom Oracle Forms applications

• Customization of Existing EBS Pages and Process Flows Oracle APEX is NOT capable of supporting this use case

Alternate Database Configuration


• APEX development performed on development instance of EBS• Not using APPS schema allows applications to run with least privilege• Privileges on APPS tables selectively granted to APEX DB schema• Look and feel can mimic EBS or use a different user interface theme• EBS Menus can be used to provide links to APEX Applications• APEX Authentication can use EBS authentication (SSO, OAM, Custom)• APEX Authorization Schemes can enforce EBS roles and responsibilities• Both SOAP and RESTful web services can be used within applications• EBS and/or APEX can be patched without impacting the other tool

Development Considerations


• Deployment is performed connected to APEX schema, not APPS• Deployment or patching of APEX applications performed using

SQL*Plus script(s)• Database resource manager can constrain APEX resource consumption• SQL within applications is run as the APEX user• APEX client info is set for each session, with application and page details• DBAs can correlate slow SQL, based on the APEX client info, to a SQL

statement defined in a specific APEX application and page• Monitoring of APEX can be done using Oracle Enterprise Manager

Deployment Considerations


• Oracle BI PublisherBI publisher is a reporting engine <> Oracle APEX is an application development toolOracle APEX uses BI Publisher to produce rich PDF output

• OBIEEOBIEE is query only <> Oracle APEX allows insert, update, deleteOBIEE supports many databases <> APEX supports only OracleOracle APEX is frequently used to add update capabilities alongside OBIEE applications

• Application Development Framework (ADF) and Mobile Application Framework (MAF)All are designed to build modern HTML Web ApplicationsAll can be used to build desktop and mobile applicationsOracle APEX is the primary tool for SQL professionals <> ADF is the primary tool for Java professionals

• Oracle FormsBoth are declarative, and leverage developers’ SQL and PL/SQL skillsOracle APEX runs Native HTML Web Applications <> Forms uses Java Applets to run on the WebOracle APEX is often used to redevelop legacy Oracle Forms applications

Comparing Application Express and Other Oracle Products


Example Integrations Oracle Application Express


• Oracle’s E-Business Suite Global Single Instance (GSI) is used by the whole organization, in every region

• Extensions are built against GSI with Oracle Application Express to meet Oracle’s own business requirements

• Special approvals need to be requested in order to modify GSI in any way other than by using Oracle Application Express extensions

• Specifications for generally applicable requirements are then sent back to E-Business Suite Development Team based on the relevant Application Express extension

Oracle’s E-Business Suite GSI [Internal Only – Intranet App]Extending our internal deployment used to run Oracle business


• Integrated with Oracle’s E-Business Suite Global Single Instance (GSI)• APEX authentication tied to EBS roles and responsibilities

Stand-alone application integrated with E-Business Suite

Quote Request System (QRS) [Internal Only – Intranet App]


Quote Request System (QRS)

• Non-EBS (local) database objects used by QRS are maintained by APEX Developers, outside of EBS database objects


• Local database views reference APPS tables• APEX Developers only see what the MISQRS schema has been granted

- Not all EBS database objects, or even all columns within an APPS table



• Data can readily be retrieved from both local APEX tables and EBS tables



• Details of quote pulled directly from EBS Quoting• Page allows comments to be placed by Sales to Quoters• Change requests and quote responses all stored in local APEX tables• Quote updates sent back to GSI via EBS APIs



http://shop.oracle.comOracle Store [Internet Application]


• Used by the public to order Oracle products

• Integrates with > 12 back-end systems

• Multi-lingual• Different business

logic for each country

http://shop.oracle.comOracle Store [Internet Application]


ARIA PeopleHR Directory [Internal Only – Intranet Application]

• Nightly download of HR data• Employees can update profile,

upload picture, add links ... • Used to contact employees,

see Org. Chart, etc.• Average ~ 1.5 million

page views / day• Average 40,000 distinct IPs• Median execution time of

0.05 seconds


• Extended E-Business Suite 11i• Migrated to E-Business Suite R12.1• EBS Responsibilities tied to Army Rank• APEX Extension completes complex

assignment by selecting Rank rather than manually maintaining responsibilities.

EBS Extension

Customer ReferenceUnited States Army


• Extended E-Business Suite (EBS)• Stand-alone application for quoting

and order entry of complex engineer-to-order assemblies

• Salesmen log into APEX not EBS• Tightly integrated with EBS for BOM,

routings, workorders, invoicing, and security
