I am wondering what to call these two versions of data modeling (primarily in SQL Server sources). I know of two ways to model data in Power Query - 1. Select a source, select the table, import it, then apply transformations like data type changes, merging etc. Carefully done, this al...
Data modeling is highly technical, a bit arcane and interdependent with databases and programming languages. In other words, the choice of the database system in which data will be stored and the language used to describe a data model can influence the development of the data model. The good ...
Data visualization, when preceded by the use of data mining and data modeling techniques, allows analysts to discover vital insights within large data sets. Data visualization helps analysts easily communicate those insights for immediate action.
