The Research And Application of Embedded Mobile Database Article by: Weibo Li, Hong Yang and Ping He Presented by: Shawn Karnoski
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
