What operation does merging records from component worksheets resemble?

Merging records from component worksheets resembles a database cross product join operation because it involves combining all the records from one worksheet with all the records from another worksheet. This type of operation produces a Cartesian product, where each record in the first set is paired with every record in the second set.

When merging, all possible combinations of the various records are considered, which is a characteristic of the cross product. This means that the outcome of merging can lead to a significantly larger set of data, as each item in one component worksheet can correspond with every item in another worksheet.

In contrast to an outer join or an inner join, which focus on matching specific records based on defined keys or conditions, the cross product join does not impose such restrictions, thereby resulting in a more comprehensive combination of data entries. The simple merge operation without filtering does not accurately capture the complexity of how the merging process relates to traditional database operations, as it lacks the relational aspect that joining implies.
