What is the most common method of specifying a primary key in a relational schema description? Group of choice: A. by enclosing the key attributes in parentheses B. by stating the key attributes first in the relation definition C. by writing key attributes in all capital letters D. by italicizing the key attributes E. by underlining the attributes that comprise the primary key
Using the STUDENT table structure in picture, do the following: 1. Write the relational schema, draw its dependency diagram and identify all dependencies, including all partial and transitive dependencies. You can assume that the table does not contain repeating groups and that any invoice number may reference more than one product. (Hint: This table uses a composite primary key.) 2. Remove all partial dependencies, write the relational schema, and draw the new dependency diagrams. Identify the normal forms for each table structure you created. 3. Remove all transitive dependencies, write the relational schema, and draw the new dependency diagrams. Also identify the normal forms for each table structure you created. 4. Draw the Crow’s Foot ERD.
Using the INVOICE table structure shown in table P6.3, do the following a. Write the relational schema, draw its dependency diagram, and identify all dependencies, including all partial and transitive dependencies. You can assume that the table does not contain repeating groups and that an invoice number references more than one product. (Hint: This table uses a composite primary key.) b.Remove all partial dependencies, write the relational schema, and draw the new dependency diagrams. Identify the normal forms for each table structure you created. Note You can assume that any given product is supplied by a single vendor, but a vendor can supply many products. Therefore, it is proper to conclude that the following dependency exists: PROD_NUM -+ PROD_LABEL, PROD_PRICE,VEND_CODE, VEND_NAME ( Hint Your actions should produce three dependency diagrams.) c. Remove all transitive dependencies, write the relational schema, and draw the new dependency diagrams. Also, identify the normal…
1. The BOOK CHECKOUT relation stores data about books checked out by students at a university. The functional dependencies are given below for this relation. a. Which normal form is this relation in and why? b. Using the normalization steps develop a set of 3NF relations for this view. Describe the relational schema for the 3NF relations that you developed. Be sure to list the referential integrity constraints BOOK CHECKOUT (StudentID, StudentName, StudentPhoneNumer, ISBN, BookTitie, CheckOutDate, ReturnDate) StudentID > StudentName, StudentPhoneNumer ISBN -> BookTitle StudentiD, ISBN ->CheckOutDate, ReturnDate
I got stuck on step one through four. I was wondering if you guys know how. each step says: Write the relational schema for the data in its current form. Identify all partial dependencies and transitive dependencies for the data in its current form. Write the relational schema to meet 3NF requirements to the greatest extent possible. If necessary, add or modify attributes to create appropriate determinants, create appropriate foreign keys, and to adhere to naming conventions. Analyze the given data and identify the business rules reflected in the data.
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…
Write only the relational schema for 1st and 2nd Normal Forms based on the following records.
Instructions: Create a complete ERD in Crow's Foot notation that can be implemented in the relational model using the descriptions below. The attributes required: Activity's ID, Activity's Title, Activity's description, Child's ID, Child's firstname and lastname, Child's Birthday, Parent's ID, Parent's number, Parent's address. The business rules are: An activity may or may not have a child signed up An activity may have many children signed up A child must have an activity A child may have many activities A child must have a parent A parent must have a child A child may have many parents A parent may have many children To submit: Write your answer in a clean sheet of paper and upload a picture of it to dropbox
Using the STUDENT table structure shown in Table 1, do the following:a. Write the relational schema and draw its dependency diagram. Identify alldependencies, including all transitive dependencies. [5 marks]b. Write the relational schema and draw the dependency diagram to meet the3NF requirements to the greatest practical extent possible. If you believe thatpractical considerations dictate using a 2NF structure, explain why yourdecision to retain 2NF is appropriate. If necessary, add or modify attributesto create appropriate determinants and to adhere to the naming conventions.[10 marks]c. Using the results of Problem b, draw the Crow’s Foot ERD.
