Description: A table column is a vertical entity in a table that contains data of a specific type. In the context of databases, each column represents an attribute of the entity being modeled, and its definition includes the data type it can store, such as integers, text strings, dates, among others. Columns are fundamental to the structure of tables, as they allow for the efficient organization and classification of information. Each row of the table, known as a record, contains a value for each column, enabling effective data querying and analysis. The correct definition and use of columns is crucial for maintaining data integrity and optimizing query performance in database management systems (DBMS). In summary, columns are key components in the organization of data in relational and non-relational databases, facilitating their manipulation and analysis.
