1. A method comprising: invoking a multi-dimensional relational database, the multi-dimensional relational database comprising a set of source data; selecting a portion of the multi-dimensional relational database to extract a set of data elements and a set of functional relationships describing relationships between values of the set of data elements of the selected portion; encapsulating the set of data elements and the set of functional relationships, of the selected portion, in a predictive database model object, wherein a modeling application performs an operation on the predictive database model object to predict an output; sending, by a client computing system, the predictive database model object, comprising the portion of the multi-dimensional relational database, to a mainframe platform, wherein the mainframe platform performs a modeling operation using the set of data elements and the set of functional relationships in the predictive database model object to change at least one of the set of data elements or the set of functional relationships in the predictive database model object; and receiving a modified predictive database model object from the mainframe platform, wherein the modified predictive database model object comprises at least one of a changed set of data elements or a changed set of functional relationships.
