Create a Crow's Foot ERD for the following description:
The KwikTite Corporation operates many factories. Each factory is located in a region, and each region can be "home" to many of KwikTite's factories. Each factory has many employees, but each employee is employed by only one factory.
A company has several employees, all with different names, who perform interviews with
job applicants (one applicant is interviewed by one employee). The job applicants also have
different names. The interviewer makes appointments for interviews with the applicants.
Each applicant may be interviewed at several occasions, possibly by different interviewers,
but in that case the interviews take place during different days.

a) From the text, find functional dependencies in the relation.
b) Find the keys of the relation.
c) Show that the relation is…

DATABASE SYSTEMS Construct an Enhanced ERD along with Possible entity clusters of the given below system. This describes the business process to publish an academic paper. The author submits a paper to an editor of a journal. The editor first checks whether the paper fit the theme of the journal. If not, the editor rejects the paper. Otherwise, the editor assigns the paper to a number of reviewers. The reviewers review the paper, and write a review. The review is sent to the editor. The editor then assesses the quality of the paper with the help of reviewers’ comments. If the quality is good, the paper will be accepted, and the author notified. Furthermore, the paper is forwarded to the publisher for publication. If the quality is bad, the editor rejects the paper.arrow_forwardDraw an ER diagram that captures the following information: A book identified by (unique Id number, a title and one or more authors), A library identified by (unique name and adders), A borrower has a name and a unique ID code.
