基于MongoDB的调查决策系统数据存储方案设计

Design of Data Storage Scheme for Investigation and Decision Making System Based on MongoDB

之前绝大多数调查决策系统都采用传统的关系型数据库进行数据存储;现今大数据时代来临,各类非关系型的数据库开始崭露头角,并在应用中所占比重愈来愈大。Mongo DB就是其中的后起之秀。因此,尝试使用非关系型数据库Mongo DB来作为调查决策系统的数据存储是非常有现实意义的。该文为大家呈现基于Mongo DB这个面向文档的非关系型数据库来设计投票及所包含问题的数据存储,在详细介绍其内嵌和引用这两种解决方式基础上最终给出后台的数据存储方案。

before the vast majority of investigation decision system use the traditional relational database for data storage; today's big data era is coming, all kinds of non- relational database began to emerge, and in the application of accounts for the proportion is more and more. Mongo DB is one of the bright younger generation. Therefore, try to use the non relational database Mongo DB as the investigation decision system of data storage is of great practical significance. In this paper we present non relational database based on mongodb this document oriented to design voting and contains data storage problem, describes in detail the embedded and refer to the two solution on the basis of finally gives the background data storage scheme.
