Throughout the Knowledge Evaluation Expressions (DAX) language, new information fields will be derived from present information inside a desk, and even from information residing in a related desk. This permits for the creation of personalized metrics, flags, or categorized values with out altering the supply information. For example, a “Complete Gross sales” column may very well be added to a “Merchandise” desk by summing associated values from an “Orders” desk. This dynamically updates each time the underlying information modifications.
This capacity to create customized fields enriches information fashions and supplies deeper analytical insights. It permits for the event of complicated calculations and key efficiency indicators (KPIs) instantly inside the information mannequin, enhancing report growth velocity and effectivity. Previous to this performance, such computations usually required preprocessing or complicated queries, leading to much less versatile reporting. Integrating derived fields instantly inside the information mannequin promotes information integrity and simplifies information manipulation for end-users.
