    Question Could Mondrian work with galaxy schema?

    Hi All,

    Could you please tell, could Pentaho Schema Workbench or Mondrian work with galaxy schema?

    I mean, if there are several Fact tables connected with each other and I want to build measures from each Fact table without creating any Views.
    Don't want to use any Views since it seems like a workaround rather than a right solution.
    Also Pentaho Aggregation Designer cannot work with Views.

    With best regards,

    I found out 2 things:
    1. In Galaxy schema, fact tables are not connected directly. They just have common dimension tables.
    2. It is not correct to build Data warehouse schema with directly linked Fact tables.

    After above findings, I understand that Pentaho Schema Workbench could not build Cube based on a such schema.
    But, for a correct galaxy schema could be used Virtual Cubes.
