This code performs a SQL query to retrieve the access names associated with a specific person based on their name. The query first joins multiple tables (Access, Role_Access_Matrix, Matrix, Person) to find access names that are linked to the person through a role. It then uses a UNION to combine the results with access names directly associated with the person through the Matrix table. The query filters the results based on the person's name and a condition on the access_fork column.
