So i was watching a breif video about converting erds into sql tables and need help understanding somethings. So in this screenshot, is this the code for establishing a relationship? ALSO, could someone explain the sql code for many-many, many-one, and one-one??????? PLEASE USE SIMPLE TABLES AND DESCRIBE EACH LINE!!! **Employee**We can use `CHECK` constraints to enforce specific values or formats:```sqlCREATE TABLE employee ( ssn CHAR(11) PRIMARY KEY, f_name VARCHAR(40), m_init CHAR(1), l_name VARCHAR(50), address VARCHAR(200), salary MONEY, gender CHAR(1) -- this really, works_for_dept INTEGER NOT NULL, FOREIGN KEY (works_for_dept) REFERENCES department(number), CHECK(ssn LIKE '[0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9][0-9][0-9]'), CHECK(gender IN ('M', 'F', 'N', 'T', 'I', 'P')));-- N=Nonbinary, T=transgender, I=intersex, P=PreferNotToAnswer```### Diagram ExplanationThe diagram illustrates relationships in a database schema with an "Employee" table connecting to a "Department" table through the "Works_for" relationship. The lines and symbols indicate:- An "Employee" working for a department.- A Foreign Key constraint (`works_for_dept`) linking to a department number.- It's a standard entity-relationship notation showing a one-to-many relationship between the tables.
