海量数据跨盘存储机制的设计与实现

Design and implementation of massive data across storage devices

针对石油勘探行业海量数据过大而单存储设备无法有效存储的问题,提出了海量数据跨盘存储机制.该机制充分利用面向对象的重载和多态技术,通过定义专门的文件类,封装标准函数库中的文件操作接口,提供对单数据体的各种文件操作,使文件跨盘存储通过软件方案得以实现.该机制有效地提高了单一存储设备存储空间的利用率.

In connection with the problem that the massive data file is too large and storage device can not be effectively stored,a mechanism of the massive data file across disk storage which make full use of object-oriented overloading and polymorphism techniques was put forward.To define a special file class,encapsulation file operations interface from the standard function library,provided a variety of file operations of the single data,make the file across disk storage can be achieved by software and improve the rate of space utilization of the single storage device.
