Create a relational diagram for the database using crow’s foot notation. The ERD should include all the entities, relationships, and connectivity where applicable. 4 tables for the database: PATRON, BOOK_COPY, BOOK, and CHECKOUT. (Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows: PATRON table records a patron’s ID, name, address, phone number, and email address. BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book. BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table. CHECKOUT table records the date of check-out, patron’s ID, the identifier of the book copy…

Create an ER model related to the following entities and relationships: Department, Student, Professor, Course, Section, Grade, Major. (For attributes inside each table, you only need to insert several reasonable attributes. No need to have a comprehensive list. For many-to-many relationship, you also need to insert one extra table to handle the many-to-many relationship. The final database design will have more tables than the number of entities listed above.) A given department can offer many courses. A given course can be offered by only one related department. A given course can have many related sections. A given professor can teach many sections. A given section can only be related to one course and taught by one professor. A given professor can have appointment with different departments A given department can have many professors. A given department can offer several majors. A given major can be offered by only one related department. A given student can have several majors. A…
Indicate the changes you need to make to the BITS database design to support the following situation. The region where clients are located is divided into territories. For each territory, store the territory number (a unique identifier) and territory name. Each consultant is assigned to a single territory. Each client also is assigned to a single territory, but the territory must be the same as the territory to which the client’s consultant is assigned. Could you also please make a diagram that shows me the type of relation between tables? for example, if it lines of the connectiones finishes with a dot or something like that.
Consider the given ER Diagram for Notown database in Figure 2. You have been tasked to recommend that Notown use a relational database system to store company data. Show the Structured Query Language (SQL) statements for creating relations corresponding to the entity sets and relationship sets in your design. Identify any constraints in the ER Diagram that you are unable to capture in the SQL statements and briefly explain why you could not express them.
Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements. There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.
