  4. 4. 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.
  5. 5. 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

  7. 7. Architecture of Oracle APEX
  8. 8. 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.
  9. 9. Browser Based application development
  10. 10. APEX hierarchical menu structure
  11. 11. 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
  12. 12. 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
  13. 13. 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.
  14. 14. 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
  15. 15. Benefits of Oracle APEX Runs within Database Self Service Provisioning Leverage SQL SkillsRapid Browser Based Development Point your browser and start developing Build reports and charts using SQL Out-of-the-box elastic private cloud service Simple to manage, highly scalable
