relations and associations

In data and database terminology, relations and associations describe how different pieces of information are connected. A relation is like a structured table that groups related data, such as a list of employees with their details. An association refers to the link between different tables or data sets, such as connecting employees to their departments. These connections help organize and retrieve related information efficiently, allowing systems to understand and manage complex data relationships—like knowing which student belongs to which class or which product is part of which order.
