Entities and Attributes are created in the database as what?

Entities and Attributes in OutSystems correspond to the fundamental structures found in relational databases. When you create an entity in OutSystems, it is implemented as a table in the database. Each attribute of that entity translates directly into a column within that table. This model reflects the standard relational database design principles, where tables represent data entities and columns represent the properties or attributes of those entities.

The reason the other options do not fit is that while tables and columns are integral to how entities and attributes are represented, indexes and constraints serve different purposes within a database. Indexes help improve the speed of data retrieval but do not correlate to entities or attributes themselves. Constraints are used to enforce rules at the database level, such as ensuring data integrity, but they do not represent the entities or their attributes directly. Therefore, the correct pairing of entities and attributes as tables and columns clearly aligns with fundamental database principles, providing a straightforward and comprehensive way to understand data structure in a relational database context.
