There is a relationship model R (employee name, project name, salary, department name, department manager). Suppose each employee can participate in multiple projects, each receive a salary; each project belongs to only one department management; each department has only one manager. If the relational model R is decomposed into two relational patterns R1 (project name, department name, department manager), R2 (employee name, project name, salary). The highest degree of normalization R1 is( ). The highest degree of normalization R2 is( ).
