This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

摘 要: 本文件是C8051单片机I2C总线读写测试程序;将跳线器JP6短接,使用外部22.1184MHz晶振. 功能:定义 0 ~ 9 键为数字键, A ~ F 为功能键。按 A 键后,可按0 ~ 9 数字键, 从零地址开始存储该键值,并送LED数码管上显示该键值。按 C 键停止后,按 B 键, 从零地址开始读取数据值,并送LED数码管上显示。读取速度每秒一次。在按 C 键停止后,可按 A 键重新输入。
