1. A computer-implemented method for monitoring a connection between computer system layers, the method comprising: detecting that an aspect is being modified in a transactional layer of an enterprise resource computing system, the enterprise resource computing system further including an analytical layer configured to receive data stored in the transactional layer from the transactional layer, wherein the analytical layer includes at least one entity selected from the group consisting of: a key performance indicator variable, a report, and a group of relational tables, the analytical layer processing the data received from the transactional layer, wherein the modified aspect is at least one of a data storage structure and a data storage process; determining, in response to the detection, whether at least one of several decoupling components is implicated by the aspect, the decoupling components being configured for use by the analytical layer in receiving the data, wherein each of the decoupling components enables communication between the transactional layer and the analytical layer; and making a predefined output to a user based on the determination; wherein the determination indicates that at least one of the decoupling components is implicated by the aspect, and wherein the predefined output identifies the at least one implicated decoupling component.
