What is the main benefit of using a relationship class in ArcGIS?

Using a relationship class in ArcGIS primarily serves the function of linking related records between feature classes. This is especially beneficial when working with complex datasets that involve relationships among various entities. For example, if you have a feature class representing buildings and another representing owners, a relationship class can effectively link each building to its respective owner based on a common attribute, such as an owner ID.

This capability allows for the organization of data in a more structured way, enabling users to query and access related information seamlessly. When working with relationship classes, users can gain insights that might not be apparent from examining individual feature classes alone. Additionally, these links support advanced querying and editing operations, enhancing the overall data management experience in a GIS environment.

Other options focus on different aspects of GIS functionalities. Data visualization is important, but it does not inherently involve the relationships between feature classes. Storing attribute data pertains to how data is managed rather than establishing connections between datasets. Performing spatial analysis relies on spatial relationships and data structures but does not address the relational aspect that is central to a relationship class.
