Why I love Apex?• Rapid reporting and data entry web applications development

environment based on your existing tables, views, PL/SQL APIs etc.

– also spreadsheet or MS Access data• For starters nearly no programming or scripting knowledge is

needed– wizards are you assistances

• Don’t have to be graphical designer– themes and templates help you – as a result you may spend your time more on the analysis of the

business needs and design of your database structure for performant database applications

• Feel all the power of an Oracle Database anywhere inside your application

– Completely database centric, integrated

Apex Development Env.• On the client; all you need is a simple web browser and a network

connection to the database which hosts your Apex applications• On the server; Apex is nothing more than data in some tables and

large amounts of PL/SQL code, it is installed into a schema of your database

– Works and supported as a component of Standard One, Standard and Enterprise Editions on Oracle Databases higher than 9iR2(9.2.0.3)
