For data blending in Tableau, there are two information sources – fundamental data source and optional data source.

Merging the data within the same data sources is data joining. All of the merged tables/sheets tables/sheets contain ordinary plans of dimensions and measures.

Blending is unique in relation to making joins since blending only combines relevant data from various information sources. while joins work on a line-level and frequently duplicated information that gets rehearsed in a few columns. The two information blending and joining create a left join between two information tables.

The central matter of contrast is when accumulation happens i.e when a join is made the information is consolidated first then at that point total. While in information blending the information from fundamental and assistant sources are required freely, accumulated, consolidated, and afterward utilized for representation. The request for activities is diverse in both.
