The Research on Embedded Database System of Wireless Network

Wireless embedded database system is more complex and flexible than conventional computing environment. Embedded database computing platform requires more technologies such as asymmetric mobility, instability connected topology diversity, network communications, highly scalable systems, low reliability. This paper described the design and development process of embedded database, analyzed the database indexes, data storage and lexical analyzer. It supports CAPI interfaces and standard SQL subset, also supports ODBC or JDBC and bi-directional data exchange, and has a two-way flow of data between the central database and the embedded database.

Research and Implement about Embedded Database System Base-on NAND Flash Memory

Currently, the embedded database technology has become a very active research field, and attracted more and more attention. This paper research how to improve the storage performance of embedded database indexing mechanism using read and write characteristics of NAND flash memory. Based on the reviewed and compared of existing design of NAND flash memory, this article expressed the design and implementation of dynamic index mechanism base on B + Tree. The prototype system combines the advantages of operation of the adapted read operation disk model and write adapted write operation log model, optimal matching and converting for storage model of each node in B + tree model while running which make a variety of devices have better read and write performance.
