Entity Relationship Model to Relational Model
We live in an era where data is the critical factor in decision-making. To provide that critical factor, we must be able to extract data from database management systems. This week, you will learn how Entity Relationship (ER) models visually show the various entities (tables) and the relationships between them. You are also provided with an introduction to SQL, the standard language for relational database management systems.

Great course. One start subtracted because many of the assignment materials were not covered at all in the course. Lots of time googling what might be meant in the exercises.
