+    - Energy (measured in joules)
+    <br />    - Transfer (measured in Bytes)
+    <br />    - Storage (measured in Bytes)<br />
+    <br />The control of these 3 impacts allows to lengthen the life of the terminals as well as reduce their energy consumption.
+    <br />The ETSdiff tool allows to measure a differential on these three values and in a given context (database and fixed measurement environment).
+    <br />The results generated by ETSdiff must help define the interest of the rule reported by Sonarqube in the context of the code analyzed.
