Inside the Knowledge Evaluation Expressions (DAX) language, new information fields might be derived from present information inside a desk, and even from information residing in a related desk. This enables for the creation of personalized metrics, flags, or categorized values with out altering the supply information. As an illustration, a “Whole Gross sales” column could possibly be added to a “Merchandise” desk by summing associated values from an “Orders” desk. This dynamically updates each time the underlying information adjustments.
This skill to create customized fields enriches information fashions and offers deeper analytical insights. It permits for the event of advanced calculations and key efficiency indicators (KPIs) straight inside the information mannequin, enhancing report growth pace and effectivity. Previous to this performance, such computations usually required preprocessing or advanced queries, leading to much less versatile reporting. Integrating derived fields straight inside the information mannequin promotes information integrity and simplifies information manipulation for end-users.
