Data modeling (data modelling)is the process of creating a data model for the data to be stored in a database. This data model is a conceptual representation of Data objects, the associations between different
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 ...
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...
Database replication involves storing copies of a database in different locations. Learn how it works and how to get started.
