This paper studies and analyzes the characteristics of
embedded database and SQLite’s characteristics, the internal
structure and the function of API. It constructs the simulation
environment of ARM-Linux and achieves the realization of
SQLite in the ARM-Linux platform. It also achieves the
application development of SQLite in the ARM-Linux
platform and calls the interface functions to manage the
database. The graphical user interface design based on Qt/Embedded has also been realized. The paper introduces
the whole process of embedded system development and has
good meaning of theory and practice. Practice has proved
that SQLite can complete the application requirement of
database in embedded system excellently. Therefore, SQLite
database is a good choice because of its special advantages in
the embedded application field and has very good future in
embedded applications.
