Draw an ERD for the following problem with attributes, primary keys, cardinalities and participation constraints and specialization, if appropriate. An information studies student wants to keep track of the following information. A publishers publishes two kinds of publications: books and journals. Any one publisher publishes at least one book and/or at least one journal. Each book can be written by one or more authors and one author can write one or more books. Each book and journal is characterized by one or more indexed keywords, which are represented by a keyword number and keyword. Not every keyword is used by the journals, however. Both books and journals have a unique number (such as ISBN# for a book and ISSN# for a journal), title and a publisher. For books, the student tracks the published year, all author information and their institutions. For journals, the student keeps the starting year first published, the number of issues to be published per year and the category of the journal (such as academic, newsletter, trade). Each publisher has name, address and phone. Each author has an ID number, name, address, phone, author's affiliated institution and the address of the institution. An author may be affiliated with more than one institution. The student would like to keep only authors who are participating in writing at least one book and institutions that have such authors.
