Step 2: Identify what a fact table is. A fact table is a central table in a star schema that stores quantitative data.
Step 3: Know that fact tables contain transactional data. This means they hold data about events or transactions that have occurred.
Step 4: Recognize that fact tables include measures. Measures are numerical values that can be analyzed, like sales amounts or quantities sold.
Step 5: Learn that fact tables also have foreign keys. These are links to dimension tables, which provide context to the measures, like time, product, or customer information.
