I would like to use our databases as efficient as possible. Data in Board database_A are loaded into entities. I need exact the same data in Board database_B. Extracting and loading the ASCII-extract is an option, but I would like to avoid this as it creates too much duplication and processing.
On a Microsoft SQL Server you would "Link" the other server to use its tables and queries.
How can I use existing entities/cubes available on database_A in database_B?
