A system for accessing data distributed on databases in an integrated computer system includes a distributed data port, which initiates a XRef server query, generates a virtual table having a first result set including at least one data row responsive to the XRef server query, initiates Populate queries each having one of the data rows as an argument, and updates the virtual table with data responsive to the Populate queries. The system also includes a XRef server, which receives the XRef server query from the distributed data port and identifies at least one of the databases having a data row responsive to the XRef server query. A temporary virtual table relays each Populate query to a data directory server, and the data directory server is linked to each of the databases. It locates at least one of the databases having data responsive to the XRef server query and the Populate query, retrieves that data, and transmits data responsive to said XRef query to the distributed data port and data responsive to the Populate query to a temporary virtual table. The temporary virtual table populates each data row of the result set with data responsive to the Populate query and transmits the populated data row to the distributed data port to update the virtual table. |
