For a project, we have several groups that will produce numbers using models. Input and output data will be in the DB. Each group is independent and works in their own different way; however, the outputs they produce will need to be combined, aggregated and queried.
I am debating whether to create one database with a lot of tables or many smaller databases which belong to each group. I am leaning towards creating multiple databses because of easier access management. However, I am concerned about performance.
Will querying tables across databases affect Teradata performance?
Thank you!
