What is the correct term for each attribute in an Entity?

In the context of databases and entity modeling, the correct term for each attribute in an Entity is "Column."

In relational databases, an Entity often represents a table, and each attribute corresponds to a specific characteristic of that Entity. These characteristics are organized into columns, where each column holds data for a specific attribute across all records (or rows) in that table.

Understanding this terminology is important for database design and implementation, as it helps clarify how data is structured and accessed. While terms like "Row," "Record," and "Field" are associated with databases and data structures, "Column" specifically denotes the vertical structure of a table where individual attributes are defined.
