- 2. What is Oracle APEX ? Oracle Application Express (APEX) is a low-code development platform that enables you to build scalable, secure enterprise apps, with world-class features, that can be deployed anywhere. https://www.oracleapextrainer.com/
- 3. Overview • Database centric development tool for Oracle Database application development. • Develop desktop and mobile applications • Targeted at developers who knows SQL and PL/SQL • 100% browser based development, deployment and runtime. • On premise, on laptop, on cloud, on RAC, any platform where Oracle DB is available. https://www.oracleapextrainer.com/
- 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. https://www.oracleapextrainer.com/

- 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. https://www.oracleapextrainer.com/
- 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.

APEX vs Forms/ Reports Area Forms APEX Architecture Metadata stored in “.fmb” file Metadata stored in db tables Programming Language PL/SQL on both client and server PL/SQL on serverside Database Connection Fixed Dynamic UI Programming Java HTML, JS, CSS Application modules Windows/ Canvas/ Block Pages/ Regions Client Control Triggers JavaScript Charts BI Beans HTML, JS, Flash https://www.oracleapextrainer.com/
- 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.
