About the course

Proficiency in structured query language (SQL) is fundamental for anyone working with data. Used in organizations large and small, learning SQL will prepare you to quickly query raw data and transform it into meaningful visualizations using tools like Tableau to help you make business decisions.

This certificate program is designed to help you analyze data in a relational database and develop your understanding of the relationship between SQL and data visualizations. You will use SQL and fundamental database concepts to create a normalized database, manipulate the data within the database, and extract the data from the database, discovering how to convert business questions into SQL queries that extract answers from your data.

After developing your skills working with databases, you will take raw data and create robust data visualizations using Tableau. You’ll explore a wide variety of charts and learn how to select the best chart to convey the meaning in your data. This combination of being able to both work with and present data to key stakeholders will prepare you to bring value to any data-centric organization.

You will be most successful in this program if you have an understanding of basic statistical concepts.

Querying Relational Databases

Data drives many real-world endeavors, which means that storing and accessing the data is foundational to success. Relational databases are an industry-standard data storage mechanism for maintaining data integrity while allowing flexible data retrieval.

You will begin this course by examining the basic table structures that form a relational database. Using the relational database format, you will define connections between your data fields and determine how those can be expressed. You will then practice normalizing a relational database to ensure data integrity and reduce redundancy. As this course concludes, you will use a relational database system called OmniDB along with structured query language (SQL) to retrieve specific information from the database.

Working with Data Using SQL

Relational databases are workhorses which form the backbone for much of the information we find at our fingertips on the internet. In this course, you will learn to create and modify databases using OmniDB and structured query language (SQL) to import data, create tables, and modify fields. You will also practice cleaning data to maintain your database and ensure that it provides accurate information. As the course progresses, you will identify questions you want answered and practice translating those questions into SQL. You will also examine different forms of outputting data from a database, including outputting to a program or text file and outputting CSV text.

Creating Data Visualizations with Tableau

In this course, you will explore how to create common visualizations based on your data and goals. We will learn the steps you must take to successfully create a great chart. These include planning the chart, collecting and preparing your data, and choosing an appropriate chart type. You'll examine the different categories of visualizations and determine the best chart for your purposes.

Enhancing Data Visualizations with Tableau

After creating an initial version of a chart, how do you make it better? In this course, we'll explore the process for creating great charts. First, you'll explore how best to plan and draft your chart. Then, you'll need to eliminate distractions in the chart to make your visualization clear. It's also important to emphasize the most critical data in your chart. We'll look at how our brains process visualizations, and how you can use this information to better design your chart. Lastly, we'll examine how to adjust a chart to target your audience and the iterative process you can use to improve it.

Telling a Data-Driven Story with Tableau

In this course, we will study how you can make a set of charts in Tableau that tell a story to help your audience understand and remember your message. We'll also talk about different approaches to handling technical or complicated content and techniques for getting feedback so that you can improve your presentation.
