数据有很多分法，有结构化，半结构化，197.154非结构化;也有元数据，主数据，业务数据;还可以分为GIS，视频，文件，语音，业务交易类各种数据。传统的结构化数据库已经无法满足数据多样性的存储要求，因此在RDBMS基础上增加了两种类型，一种是hdfs可以直接应用于非结构化文件存储，一种是nosql类数据库，可以应用于结构化和半结构化数据存储。

从存储层的搭建来说，关系型数据库，NoSQL数据库和hdfs分布式文件系统三种存储方式都需要。业务应用根据实际的情况选择不同的存储模式，但是为了业务的存储和读取方便性，我们可以对存储层进一步的封装，形成一个统一的共享存储服务层，简化这种操作。从用户来讲并不关心底层存储细节，只关心数据的存储和读取的方便性，通过共享数据存储层可以实现在存储上的应用和存储基础设置的彻底解耦。
数据处理层核心解决问题在于数据存储出现分布式后带来的数据处理上的复杂度，海量存储后带来了数据处理上的时效性要求，这些都是数据处理层要解决的问题。
