摘要
随着科学技术的飞速发展,我们已进入了一个信息化时代,社会信息化进程不断加速,人类对信息的需求与日俱增。信息的持续利用彰显出其重要性,这对信息的存储技术提出了新的要求。
在过去,谈到存储技术的发展趋势,总是用大容量、高速度、低价格和小型化来形容。但随着越来越多的关键信息转变为信息形式,使应用对存储技术产生了新的需求。数据已成为最宝贵的财富,数据是信息的符号,数据的价值取决于信息的价值。因此,信息存储系统的可靠性和可用性、数据备份和灾难恢复能力成为首要问题,也是亟待解决的问题。
本文首先论述了数字信息存储的概念、发展历史及新环境下人们对存储的新需求,然后分析了数字化存储的原理与机制以及常见的数字化存储技术,最后在前面分析的基础上针对中小企业对数字信息存储的需求,详细分析了各种存储方案并且设计了适合中小企业的数字信息存储方案。
关键词:信息化、存储技术、数字信息存储
Abstract
With the development of science and technology, we have entered an information society. The information technology is speeding. Humans continually accelerate on the information and increase demand. Information continually utilization accentuates the importance which bring new requirement of information storage technology.
In the past, when es to storage technology trends, always use large capacity, high speed, low prices and miniaturization. But as more and more critical information for the conversion of the application form, information on the new storage technology needs. Data has e the most precious wealth of information, data is the symbol, and the data value depends on the information of value. Therefore, the information store system reliability and availability, data backup and disaster recovery capability to e the first and foremost problem, it is also urgent problems.
This article first discusses the concept of digital storage information, history and the new environment people are stored in the new demands, and then analyzed the principle and digital storage mechanism, as well mon digital storage technology, and finally in the preceding analysis on the basis of information for digital storage medium - sized enterprises on the demand for detailed analysis of various storage scheme and is designed for small and medium enterprises information digital storage scheme.
Keywords: information technology, storage technology, digital information storage
