Mutual exclusion data class analysis in data governance

A computer system for performing a mutual exclusion data class analysis, the computer system comprising:

• a bus system;
• a storage device connected to the bus system, wherein the storage device stores program instructions;
• and
• a processor connected to the bus system, wherein the processor executes the program instructions to:
• identify a data class group of a plurality of data class groups that a matching data class is a member of, the matching data class matches data in a plurality of rows of a column in a data asset;
• identify data classes included in the data class group that the matching data class is a member of;
• filter a mutual exclusion data class from the data class group to form a filtered data class group for the column;
• and
• run the filtered data class group against the column of the data asset decreasing processing time and resource utilization of the computer system.

A computer program product for performing a mutual exclusion data class analysis, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method of:

• identifying, by the computer, a data class group of a plurality of data class groups that a matching data class is a member of, the matching data class matches data in a plurality of rows of a column in a data asset;
• identifying, by the computer, data classes included in the data class group that the matching data class is a member of;
• filtering, by the computer, a mutual exclusion data class from the data class group to form a filtered data class group for the column;
• and
• running, by the computer, the filtered data class group against the column of the data asset decreasing processing time and resource utilization of the computer.
