SL Operations Database will keep track of the following:
For each book SL publishes: a book name, genre, date of publication, and number of pages;
For each writer: a unique writer identifier as well as the writers name;

Each writer is represented by one agent. Each agent represents at least one writer, but can represent many.
Each book has one editor. Each editor edits at least one book, but can edit many books.
Each editor can mentor one or more other editors, but does not have to mentor any. Each editor can have at most one mentor editor, but does not have to have any.
