J2ME And Mobile Database Design

J2ME is a development platform for mobile devices and has been introduced by Sun Micro-Systems Inc. In 1999 for programming limited devices such as phones, PDAs and other small devices. But this architecture does not support APIs for data persistence management and relational database because of its limitations. This paper presents a base for local relational database and data persistence management for J2ME based applications and can be used in any database aware application in J2ME platform. In this paper and implementation of this database system mobile device and J2ME limitations have been considered. Also, the B+ tree indexing structure has been implemented in this project that allows us fast insertion, deletion, range queries, search, backup and restore mechanism for RMS based databases
