2022年大数据考点总结 .pdf

。-可编辑修改-名词解释1.Hadoop：是一个开源分布式计算平台，为用户提供了系统底层细节透明的分布式基础架构。基于Java 语言开发的，具有很好的跨平台特性，并且可以部署在廉价的计算机集群中。核心是分布式文件系统HDFS（Hadoop Distributed File System）和 MapReduce。2.HDFS：是 Hadoop 的一个分布式文件系统，它的主要设计理念为存储超大文件，最高效的访问模式是一次写入、多次读取，运行在普通廉价的服务器上。3.Hbase：是一个高可靠、高性能、面向列、可伸缩的分布式数据库，主要用来存储非结构化和半结构化的松散数据。$hbase shell4.Spark：AMP 实验室于2009 年开发，基于内存计算的大数据并行计算框架，可用于构建大型的、低延迟的数据分析应用程序5.推荐系统:是自动联系用户和物品的一种工具，通过研究用户的兴趣偏好，进行个性化计算，帮助用户从海量信息中去发掘自己潜在的需求6.网络爬虫:又称为网络蜘蛛，是一种按照一定的规则，自动的抓取万维网信息的程序或者脚本。-可编辑修改-7.大数据：一种规模大到在获取、存储、管理、分析方面大大超出了传统数据库能力范围的数据集合（1.数据量大2.数据类型多3.处理速度快4 价值密度低即Volume、Variety、Value、Velocity）8.物联网：物物相连的互联网，是互联网的延伸，它利用局部网络或互联网等通信技术把传感器、控制器、机器、人员和物等通过新的方式联在一起，形成人与物、物与物相联，实现信息化和远程管理控制9.云计算：通过整合和管理分布在网络各处的计算资源，提供可伸缩的、廉价的分布式计算能力，通过互联网以统一界面，向大量的用户提供服务的一种模式10

函数把一组键值对按照相关的规则映射成一组新的键值对，并交由归约函数处理）3.Hbase 的主要功能组件有哪些？答：（1）库函数：链接到每个客户端（2）一个 Master 主服务器（3）许多个Region 服务器4.Hbase 与传统的数据库有什么区别？答（1）数据类型：关系数据库采用关系模型，HBase 则采用了更加简单的数据模型（2）数据操作：关系数据库中包含了丰富的操作，HBase 操作只有简单的插入、查询、删除、清空等（3）存储模式：关系数据库是基于行模式存储的，HBase 是基于列存储的。文档编码:CT4X7K10B7R8 HJ9L8U1A7F8 ZK7N1N6J6M8文档编码:CT4X7K10B7R8 HJ9L8U1A7F8 ZK7N1N6J6M8文档编码:CT4X7K10B7R8 HJ9L8U1A7F8 ZK7N1N6J6M8文档编码:CT4X7K10B7R8

ZK7N1N6J6M8。-可编辑修改-（4）数据索引：关系数据库通常可以针对不同列构建复杂的多个索引，以提高数据访问性能。HBase 只有一个索引行键（5）数据维护：在关系数据库中，更新操作会用最新的当前值去替换记录中原来的旧值，旧值被覆盖后就不会存在。而在 HBase 中执行更新操作时，并不会删除数据旧的版本（6）可伸缩性：关系数据库很难实现横向扩展，纵向扩展的空间也比较有限。而 hbase正好相反。5.数据可视化思想及其作用？答：数据可视化技术的基本思想是将数据库中每一个数据项作为单个图元素表示，大量的数据集构成数据图像，同时将数据的各个属性值以多维数据的形式表示，可以从不同的维度观察数据，从而对数据进行更深入的观察和分析作用：1）观测、跟踪数据2）分析数据3）辅助理解数据4）增强数据吸引力6.云计算，物联网，大数据之间联系答：区别：大数据侧重于对海量数据的存储、处理和分析；云计算本质上通过网络以服务的方式将计算服务提供给用户；物联网的主要是实现物物相连。联系：云计算为大数据提供了技术基础，大数据为云计算提供了用武之地；物联网是大数据的重要来源，大数据也为物联网数据分析提供支撑；云计算为物联网提供海量的数据存储能力，物联网为云计算提供了广阔的应文档编码:CT4X7K10B7R8
