1.11 Oracle Lite
Oracle Lite is Oracle's suite of products for enabling mobile use of database-centric applications. Key components of Oracle Lite include the Oracle Lite Database, Mobile Development Kit, and Mobile Server (an extension of the Oracle Application Server).
Although the Oracle Lite Database engine runs on a much smaller platform than other Oracle implementations (it requires a 50K to 1 MB footprint depending on the platform), Mobile SQL, C++, and Java-based applications can run against the database. ODBC is supported. Java support includes Java stored procedures and JDBC. The database is self-tuning and self-administering. In addition to Windows-based laptops, Oracle Lite is also supported for handheld devices running WindowsCE, Palm's Computing Platform, and Symbian EPOC.
In typical usage of Oracle Lite, the user will link her handheld or mobile device running the Oracle Lite Database to a large footprint Oracle Database Server. Data will be synchronized between the two systems. The user will then remove the link and work in disconnected mode. After she has performed her tasks, she'll relink and resynchronize the data with the Oracle Database Server.
The variety of synchronization capabilities include the following:
Bidirectional synchronization between the mobile device and Oracle's larger footprint databases Publish-and-subscribe-based models Support for protocols such as TCP/IP, HTTP, CDPD, 802.1, and HotSync
You can define priority-based replication of subsets of data. Because data distributed to multiple locations can lead to conflicts�such as which location now has the "true" version of the data�automated conflict and resolution is provided. You can also customize the conflict resolution.
The Mobile Server provides a single platform for publishing, deploying, synchronizing, and managing mobile applications. The web-based control center can be used for controlling access to mobile applications. Oracle's former "Web-to-Go" product is also part of the Mobile Server and provides centralized wizard-based application development and deployment.
