What are entities and attributes created in the database classified as?

Entities and attributes created in the database are classified as tables and columns. In a relational database, an entity typically represents a table, which is a collection of related data organized in a structured format. Each row in the table corresponds to a record or instance of the entity.

Attributes, on the other hand, represent the individual data fields or characteristics of the entity and are equivalent to columns within that table. Each column holds a specific piece of information about the entity, consistent with its defined data type.

Understanding this classification is crucial as it forms the foundation for how data is organized, accessed, and manipulated within a database, which is key to effectively using platforms like OutSystems for application development.

The other classifications listed do not accurately represent how entities and attributes are commonly described in database terminology. Indexes are auxiliary structures that improve the speed of data retrieval but are not directly defined as attributes or entities. Constraints are rules applied to the fields to enforce data integrity but are not classifications of tables or attributes themselves.
