A Database Related Object is a Diagram Object that will gather data from a database.  Your diagram may include many different Database Related Objects by the time you have completed your design.  These Objects are useful for writing your own custom SQL Queries, including tables from multiple databases, or including a stored procedure.

 

In any case, you must establish a connection with a database before you proceed with including these Objects as they will be dependent upon this connection.  You can learn more about setting up your Database Connections in the Adding Data Connections section of the help documentation.  Below are the two types of Database Related Objects that you can insert into your Data Diagram.

 

Query - learn how to insert a user defined query into your Data Diagram.

Database Objects - learn how to include tables, stored procedures, and views in your Data Diagram.
