## Traditional Course Outline
1. Summarizing Data - One of the first steps in data analysis is examining data through aggregations. This chapter explores how to create aggregations in SQL Server, a common first step in data exploration. You will also clean missing data and categorize data into bins with CASE statements.
2. Math Functions - This chapter explores essential math operations such as rounding numbers, calculating squares and square roots, and counting records. You will also work with dates in this chapter!
3. Processing Data in SQL Server - In this chapter, you will create variables and write while loops to process data. You will also write complex queries by using derived tables and common table expressions.
4. Window Functions - In the final chapter of this course, you will work with partitions of data and window functions to calculate several summary stats and see how easy it is to create running totals and compute the mode of numeric columns.
