I have a work database that I restored in the 2017 MS SQL Server Management Studio. Unfortunately, it doesnt have an Entity Relationship Diagram - how the tables are linked. Is there a way I can get the diagram from the restored database? Currently, no one at my work place knows how the tables linked. Or even a way which can help me better understand the tables faster??

    Database diagrams will only help you if the tables have FKs setup between the tables. Otherwise, there is no way to programmatically determine the relationships.
