What Are Chasm Traps at Kai Michael blog

What Are Chasm Traps. In dimensional modeling, this manifests when two fact tables share a common dimension table and an analysis involves measures from both fact tables. Trap issues are common problem in relational database schemas in which a join path returns more data than expected. There is no specific option to find trap issues in. As the name says itself, these are traps. If we have chasm or fan traps, then we have a serious problem as these can impact the whole data model. For instance, consider a scenario where an employee is associated with. ‘chasm and fan trap lead to. These are inconsistencies in the data. Chasm trap occurs when the model establishes a 'many to one' connection among multiple tables. Following is the example in different notations. Chasm trap occur when a model suggests relationship between entity types however a path between certain occurrences does not. A model suggests the existence of a relationship between entity types, but the pathway does not exist between certain entity occurrences. In a complex schema, you may have a fact table with no relationship to another fact table, except that each contains a. In data modelling and in business intelligence there is something called connection traps.
