A DB/DC platform for real-time operating systems based on CTRON specifications
Takuo Nishihara, Junichi Kikuchi, T. Takehisa · 2003
A database and data communication (DB/DC) platform was developed for real-time operating systems based on CTRON specifications in order to create high performance online transaction processing systems such as network operation control systems. The DB/DC platform is designed to be portable and to achieve high performance. The authors describe the software architecture of the DB/DC platform for real-time operating systems based on CTRON specifications that supports high-level programming interfaces for transaction processing applications. The following results are shown: only 2% of the source code needs to be modified when the proposed DB/DC platform is ported to another operating system based on the CTRON specifications; the number of instructions executed in a typical transaction process is reduced by 50% compared with the former in-house DB/DC platform; and CTRON specifications fully define the functions needed to construct DB/DC platforms, so it is not necessary to define other functions to increase DB/DC platforms portability.>
