摘要:
Methods, systems and computer program products are provided which allow for accessing at least one data source by intercepting a command to a standard relational database management system and determining if the intercepted command accesses the data source utilizing a logical table name. If the intercepted command accesses the data source utilizing the logical table name, then the logical table name is translated to a physical table name. The intercepted command is the provided to the relational database management system utilizing the physical table name translated from the logical table name so as to provide access the data source utilizing the logical table name. Furthermore, if the intercepted command accesses the data source utilizing a logical table name and a logical column name, then the logical table name is translated to the physical table name and the logical column name translated to a physical column name.
