Which practice is considered critical when reviewing table design?

Identifying the relationships among the tables is a vital practice when reviewing table design because it helps ensure the integrity and efficiency of the database. Understanding how tables interconnect allows for proper normalization, which reduces redundancy and improves data consistency. When relationships are clearly defined, it assists in creating accurate queries and reports that can draw meaningful insights from the data. Moreover, knowing how different tables relate to one another enhances the database's ability to maintain referential integrity, preventing orphan records and ensuring that all data remains coherent across the system.

The other options, although they may contribute to good database practices, do not hold the same level of importance as understanding table relationships. Focusing solely on table names disregards the functional connections and data flow between tables. Understanding user permissions is vital for security but does not directly influence the structural design of the database. Evaluating the graphical representation of data is important for visualization but does not address the foundational aspects of data structure and integrity that relationships among tables provide.
