    摘要： A first data storage schema in which a characteristic in a first dimension table is mapped by a first table and a second table can be received and a second data storage schema can be received. The first table maps the characteristic to a first object that include attributes to which time information is irrelevant to data processing activities and the second maps the characteristic to a second object that includes attributes to which time information is relevant to data processing activities. The second data storage schema includes a fact table including at least some facts drawn from the first data storage schema and a second dimension table that includes at least some characteristics drawn from at least one of the first object and the second object.

    摘要： A system and method for executing a query plan are disclosed. In the system and method, a join graph is generated to represent the query plan. The join graph includes a set of plan operations that are to be executed for implementing the join graph. The query plan is received by a distributed network of a logical index server and one or more selected physical index servers. Each physical index server receives a portion of the plan operations, and determines what plan data is needed to execute the portion of the plan operations. A system and method includes a process for determining what plan data is needed from other physical index servers, or what plan data is needed by other physical index servers.
