Efficiently processing data for ever-increasing geographical applications and services, with embedded device performance, is becoming more and more of a challenge.
CellDB is an embedded DBMS that can not only solve errors and problems caused by the existing file system at source, but also quickly and efficiently handle an ever-increasing data processing demand.
CellDB provides a database system for software development and helps to solve problems easily during development. It will also help secure a clear competitive edge in the embedded market that embodies the human-oriented computing environment.
CellDB is an embedded relational database system that allows stable and methodical data management.
All data processing functions are provided through well-designed API to maximize development efficiency.
Furthermore, data exchange between applications and simple future changes and expansion ensures the development of a flexible system.
CellDB is small and light, moreover it's the supreme embedded DBMS with performance and stability that have already been proven in commercial handsets.
