16.1 Oracle9i Lite: The Internet Platform for Mobile Computing

Oracle9i Lite provides infrastructure and application services that enable the delivery of secure and personalized applications using a broad range of mobile devices. Oracle9i Lite is an add-on to Oracle9iAS, and complements Oracle9iAS Wireless, providing a complete, integrated, therefore simple mobile e-business framework. Oracle9i Lite includes two major components:

Mobile Server--This middle-tier infrastructure server acts as a gateway between mobile devices (such as PDAs, cellular phones, automotive computers, as well as traditional laptops) and the e-business application services those devices need to access. Mobile Server provides the necessary functions required to support mobile, disconnected devices.

Mobile Development Kit--This SDK provides the facilities, tools, APIs and sample code to develop mission-critical mobile, disconnected applications.

Developers have the option to choose amongst three different application models:

• Native--Applications use ODBC to access the Oracle Lite Database on the mobile device. C++, Visual Basic for Windows CE (ADOCE), Satellite Forms or Oracle Forms are typically used to build native, device-specific applications. A native application developed in C++ can be recompiled and run on multiple devices without recoding.

• Java--These Java applications invoke JDBC functions to access the Oracle Lite Database on mobile devices. The UI can be built using AWT or SWING classes. Java provides reusability and cross-platform capability which makes it the choice for applications which must run on multiple devices.

• Web--Enables developers to run existing web applications using the J2EE Java Servlets/JSP in a disconnected mode without modifying the code base. This unique feature makes it very easy to extend web applications to mobile, disconnected devices.

Mobile Development Kit supports Windows, Palm Computing, EPOC, and different flavors of Windows CE such as Windows CE 2.11, 2.12, Pocket PC, on different chip sets such as StrongARM, MIPS, SH4, and x86.
