Abstract: Systems and methods for changing a data structure, which an application program in a computer system uses to access database systems, are provided. According to an exemplary method, an application program communicates with a first database system to store entries in a source table having a first data structure. The method further includes creating a destination table in the first database system, such that the destination table has a second data structure (different from the first data structure). The method further includes recording the type of change for those entries in the source table, which are changed when the application program communicates with the source table. The method further includes copying the destination table into a second database system (the second data structure being retained in a copy of the destination table). The method further includes copying the source table in the second database system (the first data structure being retained in a copy of the source table).

Abstract: An electromechanical connector having a pair of detachably mateable contact mechanisms the housing of at least one of which includes an elastic wall to which is coupled at least one electrical contact which is either itself a magnetic member or which is coupled to a magnetic member. When the mechanisms are brought into mating proximity of one another, the magnetic member generates a force due to magnetic interaction with the other mechanism. The force causes the elastic wall to elastically yield, causing the contact to undergo an excursion into conducting relation with a corresponding contact of the other mechanism.
