Abstract

A computing system includes an application program and two data access components dmc 1 and dmc2 loaded on to a client computer. The data access components dmc1 and dmc2 provide access to data sets A and B stored on a server computer. Each data access component is arranged to handle a data query from the application program directed to its associated data set. If the structure of one of the data sets is changed, for example to add a new field, then the associated data access component is also modified. The modification to the data access component permits it to handle queries from the present version of the application program directed to the data set but designed for the data set before the change in its structure. The modification to the data access component also enables it to handle queries directed to the data set with the changed structure from an updated application program which is designed to take advantage of the new structure of the data set.
