Joining Fact And Dimension Tables at Alana Minns blog

Joining Fact And Dimension Tables. Joining the fact tables together into a single table is also a valid approach, but it may not be the most efficient option for your data volume. It’s a dimension when you need to slice the detail and it’s a fact table when you summarize values at the header granularity. Since there is a relationship between fact_table and dimension_table, you might want to do something like this: In this solution, linking the header and the detail table breaks the rules of the star schema because both tables act as a dimension and a fact table at the same time. Combining the tables will result in a larger table, which can be slower to query and consume more memory. Join between fact and dimension tables hi i have revenue fact table with 1000 records and i have a time dimension with 16000. Select fp.emp_name, fp.date, fp.apples_picked from fact_picked fp left join dim_company dc on fp.emp_name =.
