A data mining system uncovers patterns, associations, anomalies and other statistically significant structures in data. Weights secured to weight support members increase the stability of embodiments. On a first replication transaction between the two systems, a sync state table is created on an intermediate server or a server that facilitates communication between the two systems. The connecting assembly forces the first moving member and the second moving member to move simultaneously in a straight direction to enable the first installing member and the second installing member to be moved into or out of the installation state.
