SQL

Structured Query Language or SQL is the core language for Big Data analysis; by mastering it, you will enable insight-driven strategies and decision-making for your business. The program begins by making you leverage the power of SQL commands, data cleaning methodologies, and functions to aggregate, join, and clean tables and complete performance tune analysis to provide strategic business recommendations. Finally, you will learn how to apply relational database management techniques to normalize data schemas and build supporting data structures for a social news aggregator.

You must know how to structure databases properly in order to enable efficient and effective analysis and querying of data. The SQL program shows you how to use Database Definition Language (DDL) to create the data schemas designed in Postgres and apply SQL Database Manipulation Language (DML) to migrate data from a de-normalized schema to a normalized one. It also helps you understand the trade-offs between relational databases and their non-relational counterparts.

Business Analytics

In the Business Analytics program, you will learn the data skills that apply across various industries and functions. You will also learn how to analyze data and build models using Excel, query databases with SQL, and create detailed data visualizations using Tableau. Since this is an introductory program, there are no prerequisites as such. That said, having experience using a computer and knowing how to download and install applications will certainly be helpful.

The things you will learn during this course include:

  • Common ways in which people use data to answer questions
