    Explanation

    A **Relationship** in a database context is precisely defined as an association or link established between two or more entities (like tables). This is the core concept in relational database theory. 'Line' is a geometric term, not a database association; 'Primary key' uniquely identifies a record within one table; 'Records' are the individual data entries themselves, not the link between tables.
