试题四（共25分）阅读以下关于数据库架构设计的叙述，回答问题1至问题3。某软件公司欲开发一个社交网络系统，该系统能够接收多个不同种类客户端发送的信息，并将这些信息实时显示在每个客户端的页面上供客户阅读。该系统将为数以百万计的用户服务，因此，要求采用的数据库能够支持大量信息存储，能够满足并发读写要求，并要求随着数据规模的扩大，数据库系统要易于进行扩充。关于数据库架构的设计，王工和张工提出了两种模式：王工提出基于传统的关系型数据库模式，通过向上扩展( Scale-up)以满足数据库的可扩展性要求；李工提出利用新兴的NoSQL数据库模式，通过向外扩展( Scale-out)以满足数据库的可扩展性要求。项目组经过讨论，决定采用李工提出的设计方案。【问题1】（11分）请指出关系数据库模式和NoSQL模式在并发支持、存储与查询、扩展方式、索引方式和应用领域五个方面各自的特点，结果填入表4-1中(1)～(10)；并针对应用需求，说明项目组选择李工提出的设计方案的原因。【问题2】（8分）与传统的关系型数据库相比，NoSQL数据库所支持的典型数据存储类型有哪些？【问题3】（6分）在实际应用中，NoSQL数据库存在的问题有哪些？
关于存储产品的架构扩展，下列说法不正确的是（）A、Scale-out架构的存储系统在扩展之后，从用户的视角看起来仍然是一个单一的系统B、Scale-out横向扩展架构的升级通常是以节点为单位，每个节点往往将包含容量、处理能力和I/O带宽C、Scale Up主要是利用现有的存储系统，通过不断增加存储容量和控制器来满足数据增长的需求D、Scale Up方式只增加了容量，带宽、计算能力并没有相应的增加

You design a Business Intelligence （BI） solution by using SQL Server 2008. The solution includes a SQL Server 2008 Reporting Services （SSRS） infrastructure in a scale-out deployment. All reports use a SQL Server 2008 relational database as the data source. You implement row-level security. You need to ensure that all reports display only the expected data based on the user who is viewing the report. What should you do？（）A、 Store the credential of a user in the data source.B、 Configure the infrastructure to support Kerberos authentication.C、 Configure the infrastructure to support anonymous authentication by using a custom authentication extension.D、 Ensure that all report queries add a filter that uses the User.UserID value as a hidden parameter.
