Overview of this book

Every day, businesses operate around the clock and a huge amount of data is generated at a rapid pace. Hidden in this data are key patterns and behaviors that can help you and your business understand your customers at a deep, fundamental level. Are you ready to enter the exciting world of data analytics and unlock these useful insights? Written by a team of expert data scientists who have used their data analytics skills to transform businesses of all shapes and sizes, The Applied SQL Data Analytics Workshop is a great way to get started with data analysis, showing you how to effectively sieve and process information from raw data, even without any prior experience. The book begins by showing you how to form hypotheses and generate descriptive statistics that can provide key insights into your existing data. As you progress, you'll learn how to write SQL queries to aggregate, calculate and combine SQL data from sources outside of your current dataset. You'll also discover how to work with different data types, like JSON. By exploring advanced techniques, such as geospatial analysis and text analysis, you'll finally be able to understand your business at a deeper level. Finally, the book lets you in on the secret to getting information faster and more effectively by using advanced techniques like profiling and automation. By the end of The Applied SQL Data Analytics Workshop, you'll have the skills you need to start identifying patterns and unlocking insights in your own data. You will be capable of looking and assessing data with the critical eye of a skilled data analyst.

Using Python with Our Database

While R has a breadth of functionality, many data scientists and data analysts are starting to use Python. Why? Because Python offers a similarly high-level language that can be easily used to process data. While the number of statistical packages and functionality in R can still have an edge over Python, Python is growing fast and has generally overtaken R in most recent polls. A lot of Python's functionality is also faster than R, in part because so much of it is written in C, a lower-level programming language.

The other large advantage that Python has is that it is very versatile. While R is generally only used in the research and statistical analysis communities, Python can be used to do anything from statistical analysis to building a web application. As a result, the developer community is much larger for Python. A larger development community is a big advantage because there is better community support (for example, on Stack Overflow)...
