SQL Crash Course: A First Step Towards Big Data
SQL is one of the most in demand tech skills of today.
SQL (Structured Query Language) is a universal database query language widely used by large organisations to update and retrieve information from a database and is the common standard for all relational databases that most apps are built on.
Excel spreadsheets are useful for data analysis and visualisation, but can be slow, cumbersome and downright impossible to use with large datasets. Relational databases such as MySQL or powerful data warehouses such as Oracle can address many of Excel’s limitations, by streamlining and simplifying data transformations over Big Data. However, one needs to know SQL to fully harness these technologies.
About the Course
This 2-day course provides an intensive introduction to the world of databases and analysis in SQL. Students will be provided a virtual machine containing the popular MySQL database environment on their own laptops, and run queries over datasets containing millions of records. After this class, students will understand the fundamentals of standard SQL, and will be comfortable writing queries using MySQL Workbench (one of the world's most popular database tools).
