What is a degenerate dimension in a dimensional model and how can you use it for data engineering? Web degenerated dimension is a dimension table which is being derived from fact table columns. In a case, a fact table contains more than one boolean column. In order to receive a good performance both for drillthrough action and processing the following solution was found and implemented: Web the other advantage with degenerate dimensions is that they're a lot easier to build and maintain when using etl tools such as oracle warehouse builder, as you.
Web a degenerate dimension is nothing more than a dimension attribute stored in a fact table, rather than a dimension table. Web this chapter teaches you a technique for consolidating dimensions called the degenerate dimension. Sometimes a dimension is defined that has no content except for its primary key.
