Much of the world's data resides in databases. SQL (or Structured Query Language) is a powerful language which is used for communicating with and extracting data from databases. A working knowledge of databases and SQL is a must if you want to become a data scientist. The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment. The emphasis in this course is on hands-on and practical learning . As such, you will work with real databases, real data science tools, and real-world datasets. You will create a database instance in the cloud. Through a series of hands-on labs you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python. No prior knowledge of databases, SQL, Python, or programming is required. Anyone can audit this course at no-charge. If you choose to take this course and earn the Coursera course certificate, you can also earn an IBM digital badge upon successful completion of the course. LIMITED TIME OFFER: Subscription is only $39 USD per month for access to graded materials and a certificate.

数据库和用于数据科学的SQL:世界上许多数据驻留在数据库中。 SQL(或结构化查询语言)是一种功能强大的语言,用于与数据库进行通信并从中提取数据。如果您想成为数据科学家,则必须具备数据库和SQL的工作知识。 本课程的目的是介绍关系数据库概念,并帮助您学习和应用SQL语言的基础知识。它还旨在使您开始在数据科学环境中执行SQL访问。 本课程的重点是动手和实践学习。因此,您将使用真实数据库,真实数据科学工具和真实世界数据集。您将在云中创建数据库实例。通过一系列动手实验,您将练习构建和运行SQL查询。您还将学习如何使用SQL和Python从Jupyter笔记本访问数据库。 无需具备数据库,SQL,Python或编程知识。 任何人都可以免费审核此课程。如果您选择参加本课程并获得Coursera课程证书,则在成功完成课程后,您还可以获得IBM数字徽章。 限时优惠:订阅仅需每月39美元,即可访问分级材料和证书。
