1. A system comprising: a processor; a memory device a multilayer application held in the memory device and executable by the processor, wherein each application layer includes configuration settings; at least one transformation schema that includes rules to transform configuration settings between application layers and to link at least one configuration setting of a first layer to at least one configuration setting of a second layer according to a set of transformation rules, wherein at least one transformation rule causes the at least one configuration setting of the first layer to be hidden from the at least one configuration setting of the second layer based on the at least one transformation rule conditioning the at least one hidden configuration setting of the first layer on the at least one configuration setting of the second layer; and a transformation engine executable by the processor to transform configuration settings between application layers as a function of the at least one transformation schema.
