Data quality evaluation

A computer program product comprising:

• one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to receive at least one data set and a list of rule expressions to bind;
• program instructions to build candidate binding combinations between columns of the at least one data set and variables of each rule expression in the list of rule expressions based on similarities between names of the variables of each rule expression in the list of rule expressions and names of the columns of the at least one data set;
• program instructions to build a new bound rule expression candidate based on the candidate binding combinations;
• program instructions to generate a new bound rule expression based on the new bound rule expression candidate and a data transformation applied to at least one of columns of the at least one data set;
• and
• program instructions to evaluate the new bound rule expression against data stored in the at least one data set.

A system comprising:

• a processor, a computer readable memory, one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:
• receive at least one data set and a list of rule expressions to bind;
• build candidate binding combinations between columns of the at least one data set and variables of each rule expression in the list of rule expressions;
• build a new bound rule expression candidate based on the candidate binding combinations;
• generate a new bound rule expression based on the new bound rule expression candidate and a suggested data transformation to apply to at least one of the columns of the at least one data set that is determined based on a past binding of a same variable in the new bound rule expression to the at least one of the columns of the at least one data set;
• and
• store the new bound rule expression.
