Mapping instances of a dataset within a data management system

A system for mapping data stored in a data storage system, the system including:

• means for processing specifications of dataflow graphs that include nodes representing computations interconnected by links representing flows of data, with at least one of the dataflow graphs receiving a flow of data from at least one input dataset and at least one of the dataflow graphs providing a flow of data to at least one output dataset;
• means for identifying one or more sets of datasets, where each dataset in a given set matches one or more criteria for identifying different versions of a single dataset each version of the single dataset representing data received or provided by a different one of the dataflow graphs;
• means for providing a user interface to receive a mapping between at least two datasets in a given set;
• and
• means for storing the mapping received over the user interface in association with a dataflow graph that provides data to or receives data from the datasets of the mapping.

A computer-readable medium storing a computer program for mapping data stored in a data storage system, the computer program including instructions for causing a computer to:

• process specifications of dataflow graphs that include nodes representing computations interconnected by links representing flows of data, with at least one of the dataflow graphs receiving a flow of data from at least one input dataset and at least one of the dataflow graphs providing a flow of data to at least one output dataset;
• identify one or more sets of datasets, where each dataset in a given set matches one or more criteria for identifying different versions of a single dataset, each version of the single dataset representing data received or provided by a different one of the dataflow graphs;
• provide a user interface to receive a mapping between at least two datasets in a given set;
• and
• store the mapping received over the user interface in association with a dataflow graph that provides data to or receives data from the datasets of the mapping.
