Information association and suggestion

A method, comprising:

• receiving a plurality of data groups of a first set comprising a first data group and a second data group, wherein each of the plurality of data groups comprises one or more values;
• identifying a plurality of affiliations based on the one or more values of the plurality of data groups;
• generating, iteratively, based on a value in the first data group being equivalent to a value in the second data group, a list of key values comprising each of the one or more values in the plurality of data groups;
• generating, iteratively, based on the value in the first data group being equivalent to the value in the second data group, for a key value of the list of key values, one or more data groups of a second set that comprise the one or more values of a data group of the first set from which the key value is generated;
• generating, iteratively, based on the value in the first data group being equivalent to the value in the second data group, for the key value, a data group of a third set comprising each unique value of the one or more data groups of the second set generated for the key value;
• performing a data control operation on the first data group, the second data group, and the data group of the third set that is associated with a target key value equivalent to the one or more values of the first data group and the second data group;
• and
• providing a suggestion to a user associated with the first data group to add at least one value from the second data group to the first data group, wherein the suggestion is based on the first data group and the second data group being associated with a same affiliation of the plurality of affiliations and the at least one value from the second data group is absent from the first data group prior to generating the list of key values comprising each of the one or more values in the plurality of data groups.
