ESDBMS安全后端模块的设计与实现

Design and Implementation of ESDBMS Safe Backend Module

为了使ESDBMS安全后端模块能有效地管理存储空间、快速检索数据库文件中的信息、提高存储管理的安全性,采用了分层设计的思想,对ESDBMS的安全后端模块进行整体框架设计和子模块划分,并分别对Cache管理子模块、表和索引管理子模块、加密子模块和OS子模块进行了设计,设计和实现了ESDBMS安全后端模块,该安全后端模块有利于拆卸和扩充,有利于实现ESDBMS整体的模块化,具有良好的实用性和创新性。

For the purpose that the ESDBMS safe backend module could effectively manage the storage space,fast retrieve information in database file and raise the security of storage management,and with the idea of hierarchical design,the overall frame design and the submodule division are done on the ESDBMS safe backend,and the cache management submodule,the table and index management submodule,the encryption submodule and the OS submodule are designed separately.Thus the ESDBMS security backend module is designed and implemented.The safe backend module is conducive to disassembly and expansion,and to achieving the overall ESDBMS modularization,and is of excellent practicability and innovative significance.
