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

**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](https://dba.stackexchange.com/questions/63790/conversion-of-simple-erd-to-table-is-the-solution-below-any-good) . ---------- **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?
