| Abstract: |
| The present monograph describes changes performed on the JDBC driver and in Global Conceptual Schema (GCS) Editing Tool of Gonçalves (2007). This driver aims to provide connections and searchs through heterogeneous databases, local or remotely distributed, through data horizontal fragmentation technique. The GCS Editing Tool is responsible for creating a XML file containing GCS. The changes performed trough the driver involve grouping and ordination of querys in distributed context, whereas in Gonçalves (2007) this was not possible. The solution to gathering was to implement an algorithm based on hash and ordination the creation of a comparator class. Regarding the GCS Editing Tool, it was created the routine to write the XML and improvements were made in the interface. |
