Databases are a requirement for virtually all organizations as a way of storing information digitally, with SQL employed as the main programming language to communicate with and manipulate those databases.

In this course, you will discover how datasets can be explored and manipulated using SQL. You will go from exploring what SQL is and writing your first query to understanding how to produce categorically targeted summary statistics from a large database. Along the way, you will explore a large dataset, filter and group data based on categorical and conditional preferences, and order that data, thereby yielding valuable insights and exemplifying best practices to bring back to your role.

Many different business applications rely on SQL as a backend process to communicate with and manipulate databases, which provides the information and statistics required for related business operations.

In this course, you will practice integrating and analyzing data from multiple tables. You will discover how to fully utilize the structure of relational databases and apply that knowledge to understand how highly complex business questions are answered. Along the way, you will identify how to systematically approach queries using an assortment of new clauses, thereby expanding your problem-solving capacity and ability to deliver varied outputs of your own choosing.

The following courses are required to be completed before taking this course:

  • Exploring Data

The degree to which business decisions are informed is dependent on the accuracy of related analytics reports, which requires that you assess performance regularly using the latest data. Standardized SQL code is often implemented to ensure that summary reports are up to date for businesses, but this process can be a challenge for teams.

Instead, in this course, you will assess how to extract insights from data more efficiently using a variety of new tools. You will work with time-stamped data and explore how large, intricate queries can be simplified and more easily debugged. Along the way, you will discover how to approach queries using conditional logic and temporary tables, empowering you to resolve complex problems efficiently.

In this digital landscape, SQL and relational databases form the backbone of virtually all critical infrastructure in the United States. The organization and security of those databases, however, is dependent on the manner of their construction, which determines how data is accessed and protected. Your team's ability to construct and manage a database effectively is therefore critical.

In this course, you will approach database design from a perspective focused on data security and integrity. You will go from learning how to approach general security to understanding how to properly execute modifications so that data integrity is preserved. Along the way, you will discover how to systematically design, build, and manage databases while prioritizing data integrity and security, which will maximize their utility for your organization.

The following courses are required to be completed before taking this course:

  • Exploring Data
  • Integrating Data From Multiple Tables
  • Extracting Insights From Data

To make informed business decisions, modern organizations need data to be effectively integrated, manipulated, and analyzed on a colossal scale. While SQL is a relevant piece of this process, there are a variety of other tools that can be used to make that data actionable. Your ability to manage large datasets effectively may therefore require the incorporation of additional programming languages and platforms to provide specific analytics.

In this course, you will examine how to approach large datasets accurately and efficiently with a focus on scalability and automation. You will go from identifying how to efficiently manipulate and analyze large datasets to understanding how SQL relates to the infrastructure underlying all modern web services. Along the way, you will work with more complex joins, discover how to systematically debug, and understand how SQL can be integrated with other programming languages, supporting your skills in this crucial area of digital business operations.
