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.
