Introduction
Traditional distributed databases are based on fixed network
connections and high bandwidth
The explosion in popularity of mobile computing puts these
traditions in doubt
Mobile computing has characteristics such as low bandwidth,
frequent connection loss and limited power supply that make
it difficult to use a traditional distributed database
An Embedded Mobile Database seeks to improve the
efficiency of data access as well as maintain the reliability and
uniformity of the transmission for mobile devices
Definition of an
Embedded Mobile Database
Embedded Mobile Database is:
a database management system to support mobile
computing or certain computing modes
integrated with a database system, operating
system and practical application
able to run on various intelligent embedded
equipments and mobile devices
Architecture of an Embedded
Mobile Database
It can be described as a distributed database in a
mobile environment
An extension of a traditional distributed database
system where users are dynamically connected
with the servers
Characteristics of an
Embedded Mobile Database
Dynamically distributed
Mini kernel structure
Transaction management
Data synchronization
Support for standard SQL and various
connection protocols
Full database management function
Various embedded operation systems
Data Transmission Reliability
Embedded Mobile Databases use the following
technologies/techniques to increase data
transmission reliability
Multithreading
Data reproduction/buffering
Conflict Detection
Each are designed to counteract some of the
major weaknesses of the mobile platform, such
as small memory, weak computing ability, low
power and intermittent connectivity
