## Learning Outcomes
- Determine how filter context and relationships affect DAX calculations.
- Identify how to create and manage DAX measures used in report analysis.
- Identify the appropriate DAX function to create calculated tables or columns.
- Identify the correct aggregation or counting function to summarize data in DAX.
## Traditional Course Outline
1. Setting up Data Models with DAX - In this chapter, you'll write custom functions to create new tables and calculated columns.
2. DAX and Measures - In this chapter, you'll write custom functions to create calculated measures. You'll also get introduced to variables to make writing DAX functions more efficient.
3. Filtering and Counting with DAX - Expand your DAX power with some commonly used DAX measures. This chapter focuses on filtering and counting functions.
4. Iterating Functions - This chapter covers the core concept of another powerful set of DAX functions, the so called iterating functions. You will explore iterations with exercises focusing on ranking and iterating your data.
