A method, system, and computer program product using a data dictionary to automatically determine an upgrade edition of relational database table in a database installation. The editioning method commences upon receiving a data dictionary of the database comprising at least entries corresponding to a first edition of the relational database table, then reading entries of the data dictionary to identify at least one relational database table column of the relational database table that has a revision identifier. The revision identifiers are used to determine a first edition (e.g., a run edition) and a second edition (e.g., an upgrade edition). Then, the method proceeds by creating at least a first relational database table view corresponding to the first edition of the relational database table; and creating at least a second relational database table view corresponding to the upgrade edition of the relational database table using the identified relational database table column.

Using a data dictionary to determine an upgrade edition of a relational database table

A method for transparently upgrading derived database objects commences upon analysis of the data dictionary definition for an initial derived database object as compared to the data dictionary definition for a patched derived database object, then determining if a regenerated instance of the derived database object would be logically different from the initial derived database object. The determination is based on comparisons of the definitions of the initial derived database objects and patched definitions of respective database objects. The method produces a regenerated instance of the derived database object when a regenerated instance of the patched derived database object would be logically different from the initial derived database object. The method will suppress the production of a regenerated instance when a regenerated instance of the derived database object would not be logically different from the initial derived database object. Once regenerated or suppressed, a post-upgrade software application accesses the regenerated derived database object instance (if regenerated) or the initial derived database object if the regenerated instance was suppressed.

Transparently upgrading derived database objects

A method of forming a floor polisher mounting disk is provided which includes the steps of injection molding plastic hub and rim portions, annealing the plastic hub and rim portions, and therafter injection molding a relatively soft plastic material to overlie and interconnect the plastic hub and rim portions.

Method of making a mounting disk for a floor polisher

A floor polisher mounting disk for mounting a polishing pad on a motorized floor polishing machine is provided which is characterized by the ability to readily flex upon encountering a protuberance in a floor such as a door threshold. The mounting disk includes a hum portion and a rim portion which is positioned in spaced relation to the hub portion, resilient plastic means interconnecting the two portions for providing a pliable interconnection between the two, and a resilient lip extending from the resilient plastic means for mounting a polishing pad thereon. A method of forming the floor polisher mounting disk is also provided which includes the steps of injection molding a plastic hub and rim portion, annealing the same, and thereafter injection molding a relatively soft plastic material to overlie and interconnect the hub and rim portions.
