Use EdrawMax or EdrawMax Online to create a personal coach management entity-relationship (ER) diagram. Personal coach management entity-relationship diagram has entities like User, Coach, Habit, and Check-in details. User entities will have attributes like Habit_number, Name, User_ID, and Coach_ID. At the same time, Coach entities will have Name and Coach_ID as the attributes. It should be noted here that the ER diagrams are also used to analyze existing databases to find and resolve problems in logic or deployment. These ER diagrams for personal coaches give a snapshot of how these entities relate to each other. These ERDs contain different symbols and connectors that visualize important information like significance to represent entities within the system scope and the inter-relationships among these entities.
