Just like most software applications, developers are writing artificial intelligence projects in multiple languages, but there isn't a perfect programming language that can be fully equipped with artificial intelligence projects.

The structure of Hive, as shown in the diagram, is mainly divided into the following parts: User interface, including Cli,client,wui. Meta-data stores, typically stored in relational databases such as MySQL, Derby. Interpreter, compiler, optimizer, executor. Hadoop: Store with HDFS and compute using MapReduce. There are three main user interfaces: Cli,client and Wui. One of the most common is when the cli,cli start, it will start a ...

It provides a range of tools for data extraction, transformation, and loading, a mechanism for storing, querying, and analyzing large-scale data stored in Hadoop. Hive defines a simple class SQL query language, called QL, that allows users who are familiar with SQL to query data. Act as a part of

1. The introduction of the Hadoop Distributed File System (HDFS) is a distributed file system designed to be used on common hardware devices. It has many similarities to existing distributed file systems, but it is quite different from these file systems. HDFS is highly fault-tolerant and is designed to be deployed on inexpensive hardware. HDFS provides high throughput for application data and applies to large dataset applications. HDFs opens up some POSIX-required interfaces that allow streaming access to file system data. HDFS was originally for AP ...

Not only users and vendors, but also implementation. The implementing party needs to understand the latest requirements and deployment situation of the enterprise in time, especially the problem, and adjust its implementation system continuously based on the function of CRM and the continuous adjustment of the scope of implementation. 　　At the same time, from the function of CRM and implementation of the extension is a business case with the user manual. Therefore, the function and implementation of CRM is very important, and a mature function and implementation of almost derivative CRM industry many branches, such as: System selection requirements bidding, software requirements report, implementation requirements report, user use hand ...
