The Model of Common Data Security Access

摘要

The paper provides the model called the common data security access (CDSA), which can be used to keep data consistency. And the paper describes the method that is used by the CDSA to keep the local process-process and remote process-process access the common data safely. The model of CDSA can help to manage and synchronize data abstractly. So, it keeps the consistency and integrity of data. And, it is useful for software engineer to maintain the data of system software. Based on the model, software engineer can realize remote procedure call (RPC). The mechanism and principal of the model are similar to the international standard of RPC and distributed computer. But, the model can be used in more complexes environments, for example, cross-processes, cross-system, cross-compute and cross-platform.
