基于生命周期法的图书馆存储建设过程分析

Analysis of Library Store System Construction with Life Cycle Method

借助结构化生命周期法的思想,将存储建设过程划分为规划阶段、分析阶段、设计与实施阶段、运行与维护阶段四个阶段,以实现各个工作阶段的明确划分和工作任务的明确规定.将图书馆存储数据分为三类(可重获数据,不可重获数据和核心数据),并设计存储需求表,以更为清晰、完整地表达图书馆存储需求.并针对三类数据提出分级备份策略,探寻一条图书馆存储建设的新思路.

Using structural life cycle method, storage construction process is divided into four stages：the planning stage ,the analysins stage ,the design and implement stages,the operation stage and the maintenance stage,which make the tasks of each stage clear. Based on the data from library database divided into three categories（ restorable data,unrestorable data, core data）and the demand list of store designed in this paper, the store demand of library is expressed clearly and completely. The grading backup strategy for three knids of data is provided to explore a new idea to the storage construction of library.
