Can you explain the concept of the 'own table' field in the context of databases and how it is used?

In the context of databases and ORM (for example, in C# with Entity Framework), the term "own table" usually refers to the concept where an entity or object is stored in a separate, dedicated table rather than in a shared table with other entities.
This is often used when implementing "one-to-one" relationships or inheritance, where child classes have their own tables.
For example, if you have a class "User" and a class "UserProfile", and each profile is stored in a separate table, then the "UserProfile" table is considered the "own table" for that entity.
Using a dedicated table allows:
- Storing data specific to the entity separately.
- Improving the structure and readability of the database.
- Managing relationships between tables through foreign keys.
Example:
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public UserProfile Profile { get; set; }
}
public class UserProfile
{
public int Id { get; set; }
public string Address { get; set; }
public int UserId { get; set; }
public User User { get; set; }
}
Here, UserProfile will be stored in its own table, linked to the User table via UserId.
