all the records for one application have been loaded and stored that application may no longer require a channel to database 29 and therefore the open channel may be dedicated to b o collection 24 f which may require a channel 0055 fig5 shows a schematic diagram of an exemplary embodiment of the present invention showing database 29 and b o collections 24 a 24 b with buffer memories 42 a 42 b having records 51 a i b o collections 24 a 24 b are both part of application 40 and may represent queries tiles or windows open in the user interface application 40 may alternatively have more or fewer b o collections each of b o collection 24 a 24 b has an associated buffer memory 42 a 42 b b o collection 24 a includes buffer memory 42 a which in turn stores records 51 a f b o collection 24 b includes buffer memory 42 b which in turn stores records 51 d i b o collections 24 a 24 b may include redundant records in respective buffer memories 42 a 42 b for instance records 51 d f keeping redundant records 51 d f stored in two or more separate.
