This Specialization teaches the essential skills for working with large-scale data using SQL.
Maybe you are new to SQL and you want to learn the basics. Or maybe you already have some experience using SQL to query smaller-scale data with relational databases. Either way, if you are interested in gaining the skills necessary to query big data with modern distributed SQL engines, this Specialization is for you.
Most courses that teach SQL focus on traditional relational databases, but today, more and more of the data that’s being generated is too big to be stored there, and it’s growing too quickly to be efficiently stored in commercial data warehouses. Instead, it’s increasingly stored in distributed clusters and cloud storage. These data stores are cost-efficient and infinitely scalable.
To query these huge datasets in clusters and cloud storage, you need a newer breed of SQL engine: distributed query engines, like Hive, Impala, Presto, and Drill. These are open source SQL engines capable of querying enormous datasets. This Specialization focuses on Hive and Impala, the most widely deployed of these query engines.
This Specialization is designed to provide excellent preparation for the Cloudera Certified Associate (CCA) Data Analyst certification exam. You can earn this certification credential by taking a hands-on practical exam using the same SQL engines that this Specialization teaches—Hive and Impala.
응용 학습 프로젝트
Each course in this Specialization includes a hands-on, peer-graded assignment. To earn the Specialization Certificate, you must successfully complete the hands-on, peer-graded assignment in each course. For this Specialization, there is not a separate Capstone Project like there is in some other Coursera Specializations.

Foundations for Big Data Analysis with SQL
323개의 평가
In this course, you'll get a big-picture view of using SQL for big data, starting with an overview of data, database systems, and the common querying language (SQL). Then you'll learn the characteristics of big data and SQL tools for working on big data platforms. You'll also install an exercise environment (virtual machine) to be used through the specialization courses, and you'll have an opportunity to do some initial exploration of databases and tables in that environment.
Analyzing Big Data with SQL
166개의 평가
In this course, you'll get an in-depth look at the SQL SELECT statement and its main clauses. The course focuses on big data SQL engines Apache Hive and Apache Impala, but most of the information is applicable to SQL with traditional RDBMs as well; the instructor explicitly addresses differences for MySQL and PostgreSQL.
Managing Big Data in Clusters and Cloud Storage
76개의 평가
In this course, you'll learn how to manage big datasets, how to load them into clusters and cloud storage, and how to apply structure to the data so that you can run queries on it using distributed SQL engines like Apache Hive and Apache Impala. You’ll learn how to choose the right data types, storage systems, and file formats based on which tools you’ll use and what performance you need.

Is there a fourth course in this Specialization?
A fourth course entitled Advanced SQL for Big Data Analysis is currently under development. When it is completed, it will be added to this Specialization.
What are the hardware and software requirements for the exercise environment?
To use the hands-on environment for the courses in this Specialization, you need to download and install a virtual machine and the software on which to run it. Before continuing, be sure that you have access to a computer that meets the following hardware and software requirements: • Windows, macOS, or Linux operating system (iPads and Android tablets will not work) • 64-bit operating system (32-bit operating systems will not work) • 8 GB RAM or more • 25GB free disk space or more • Intel VT-x or AMD-V virtualization support enabled (on Mac computers with Intel processors, this is always enabled; on Windows and Linux computers, you might need to enable it in the BIOS) • For Windows XP computers only: You must have an unzip utility such as 7-Zip or WinZip installed (Windows XP’s built-in unzip utility will not work)
Will I earn the Cloudera Certified Associate (CCA) Data Analyst credential for completing this Specialization?
Successfully completing this Specialization confers a Coursera Specialization Certificate. This is different from the Cloudera Certified Associate (CCA) Data Analyst credential. You can earn the CCA Data Analyst credential by passing a 120-minute performance-based exam. For pricing and other details, see CCA Data Analyst. If you complete this Specialization, including the honors lessons, then you should be well prepared to take the certification exam, but we cannot guarantee that you will pass it and earn the certification credential.
What is the hands-on Capstone Project for this Specialization?
Each course in this Specialization includes a hands-on, peer-graded assignment. To earn the Specialization Certificate, you must earn the Course Certificate for each course in this Specialization. This requires that you successfully complete the hands-on, peer-graded assignment in each course. For this Specialization, there is not a separate Capstone Project like there is in some other Coursera Specializations.
I want to purchase this Specialization for my employees! How can I do that?
