This is a very important interview question. The â€œFact less Fact Tableâ€ is a table which is similar to a Fact Table except for having any measure; I mean that this table just has the links to the dimensions. These tables enable you to track events; indeed they are for recording events. Fact less fact tables are used for tracking a process or collecting stats. They are called so because the fact table does not have aggregator numeric values or information. They are mere key values with reference to the dimensions from which the stats can be collected
