Data structure advice

[Syndicate_Admin]

Hello

I have to create a report, the data is in SQLServer, and they accumulate in separate annual tables, i.e. the same table with the same data exists for 2017-2021 and each year a new one, so currently I have 5 equal tables for sales and 5 equal tables for workers, the tables have several common fields to be able to cross them.

I have unified the 5 tables in one for sales and another for professionals, do you see the best option?

How would you do modeling?

@Syndicate_Admin , If data have the same structure combing them into one is a good idea it will reduce the lot of overhead of measures you need.

Just create need dimensions and work with them.  Try to have a star schema
