+\subsubsection{Post-Processing of Query Results and Compression During Transmission}
+
+All computing required for a given query needs to happen in the DBMS. The SUT's test driver shall not post-process query results in a way that changes their value. For example, it is not allowed to return floating-point values with a precision of 0.5 that are encoded as integers and divided by 2 on the client side.
+
+Note that \emph{lossless compression} during the communication between the test driver and the DBMS is allowed. For instance, as long as the DBMS uses a data type that conforms with the schema requirements for a given attribute, one can apply compression to send it back to/from the driver and decompress it. For example, for complex query Q14 in the Interactive v1 workload, the implementation should ultimately produce a floating point score.
+
+The same applies for query parameters. At both the client's and the server's endpoint, the correct fully qualified datatype must occur, but during transmission, it is allowed to apply compression.
