Implementing a simple ERD in MySQL: is the implementation below 100% compliant with the ERD?

Question

ERD

Consider the following ERD:

---

Tables

From it, I derived the following tables:

Company
------------------
c_id        c_name
------------------

CompanyEmail
------------------
c_id        e_id
------------------

Email
------------------
e_id        e_addr
------------------

Note: the use of the relationship table (CompanyEmail) is not arbitrary.

---

Implementation

From those tables, I made the following implementation (tested in MySQL Workbench 6.1):

• http://pastebin.com/3A0H21kw (please bear with my lack of skills :)

I guess the most important part of it (besides learning the language) was deciding which attribute is FK and the use of CASCADE. Is it [CASCADE] the implementation of parcial/strong participation? and/or weak/strong entity?

Question

• Does my implementation accurately complies with the ERD? If not, what would be a better solution?
