1. A computer-implemented method of outputting data by an in-memory database system that stores the data, comprising: storing, by the in-memory database system, a first data model that corresponds to accessing first data stored by a data warehouse system, wherein the first data model includes a data cube and a characteristic; storing second data by the in-memory database system, wherein the in-memory database system is unable to access the second data using the first data model; converting, by the in-memory database system, the first data model into a second data model that corresponds to accessing the second data, wherein converting the first data model into the second data model includes converting the data cube into an analytic view and converting the characteristic into a shared attribute view; and outputting, by the in-memory database system, the second data according to the second data model.
