1. A method for processing a data management request, comprising: determining user intent that defines properties of target data that is created from source data by performing one of (1) moving and (2) copying the source data to the target data, wherein the user intent describes transformations to be applied on the source data, access constraints on the target data, and lifecycle requirements of the target data; determining policies and constraints for the data management request that provide information on how the source data is to be processed to create the target data; creating an abstract data management request that identifies the source data, the target data, and the policies and constraints; identifying a technology among multiple technologies based on the user intent and the policies and constraints to perform one of (1) the moving and (2) the copying; creating a concrete data management request using the abstract data management request to create the target data from the source data using the technology by performing one of (1) the moving and (2) the copying; and selecting a data management engine that is associated with the identified technology and that executes the concrete data management request.
