In tableau software, data blending is a technique to combine data from multiple data sources in the data visualization. [17] A key differentiator is the granularity of the data join. When blending data into a single data set, this would use a SQL database join, which would usually join at the most granular level, using an ID field where ...
Data integration refers to the process of combining, sharing, or synchronizing data from multiple sources to provide users with a unified view.

An example of such is the classic merge that appears frequently in merge sort examples. The classic merge outputs the data item with the lowest key at each step; given some sorted lists, it produces a sorted list containing all the elements in any of the input lists, and it does so in time proportional to the sum of the lengths of the input lists.
Sort multiple fields: Specifies whether the product supports sorting by multiple fields (columns). Statistics : Specifies whether the product supports calculation and presentation of various statistics on a specific field (e.g., for the values of a numeric field such as a total number of positive numbers, total number negative numbers, average ...
