This homework aims to analyze schemas to determine dependencies and convert them to BCNF. Remember to state any assmptions you make. 1. Suppose we have the Schema R(A, B, C, D, E) and the dependencies: Dependency A > B, C C, D→E B> D E > A Туре a. Identify a correct primary key for the table using the relational schema notation (i.e., bold and underline) given the dependencies above. R(A, B, С, D, E) b. Identify each dependency as functional, full, partial, transitive, or multivalued. Place your answer in the table above. list

Normalize Table 1 to a set of Third Normal Form (3NF) relations. Your answer should show all the three stages of normalization (1NF, 2NF and 3NF) by using the Database Design Language format (underline all primary keys, composite keys and use an * to indicate the foreign keys). State the action taken upon the table(s) for each Normal Form. For the INF in this case, only identify the Primary Key and keep the INF result in a single table. Then, split into new table(s) starting from a) 2NF onwards. Also, consider the following assumptions: - One ReservelD can have multiple venues' booking. - One venue can only be booked once for the same ReservelD on the same ReserveDate ReservelD ReserveDate StartTime EndTime VenuelD VenueTag 10:00 13:00 210101-01 3-Jan-21 210101-02 3-Jan-21 Hibiscus Lily VenueSize FeePerHour Purpose |150 15:00 v10 Small Discussion 20:00 20:00 21:00 V22 Medium 260 Forum 210101-02 3-Jan-21 13:00 V20 Petal Medium 260 Meeting 210101-02 3-Jan-21 17:00 V10 Hibiscus Small 150…
In this part you will be to map the EER schema design to a relational database schema, and create the tables corresponding to the relational schema using the MySQL. You will add to your report a listing of the CREATE TABLE statements. Specify as many constraints (key, referential integrity) as you can in the relational schema. You should state the choices you made during the EER-to-relational mapping, and the reasons for your choices

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
Let R and S be two relations with the following schema: R (P. Q. R1, R2, R3) S (P. Q S1, S2) Where (P, Q] is the key for both schemas. Which of the following queries are equivalent? Ilp (R S) lp (R) Ilp (S) Ilp (lpo (R) N lp,g (S)) Пр (Про (R) - (Пре (R) Про (S))) I. II. III. IV.
Implement a new independent entity phone in the Sakila database. Attributes and relationships are shown in the following diagram: The diagram uses Sakila naming conventions. Follow the Sakila conventions for your table and column names: All lower case Underscore separator between root and suffix Foreign keys have the same name as referenced primary key Write CREATE TABLE and ALTER TABLE statements that: Implement the entity as a new phone table. Implement the has relationships as foreign keys in the Sakila customer, staff, and store tables. Remove the existing phone column from the Sakila address table. Step 2 requires adding a foreign key constraint to an existing table. Ex: ALTER TABLE customer ADD FOREIGN KEY (phone_id) REFERENCES phone(phone_id) ON DELETE SET NULL ON UPDATE CASCADE; Specify data types as follows: phone_id, phone_number, and country_code have data type INT. phone_type has date type VARCHAR(12) and contains strings like 'Home', 'Mobile', and 'Other'.

a. Identify all dependencies, including all transitive dependencies. b. write a relational schema (shorthand notation) to meet 3NF reqirements. Unless a 2NF structure is more accurate then use that and explain why. c. draw a crows foot ERD using this information

For developing our queries, we will be using the following relational schema: Student(SID, name, username, major) Course(cname, description, department, weight) Offering(OID, cname, year, term, duration) Enrolled(SID, OID, grade) A course relation is the generic description of a course which is offered by a department. The offering relation is the specific instance of a course being taught in a given term, and is the entity which will be associated with the student enrollment. Students are enrolled in these offerings and achieve a mark. Express each of following queries in Relational Algebra: | Write a relational algebra query which will list the cname and description of all the courses which are being offering in the Fall 2018 term. 2 Write a relational algebra query which will list the name of all the students who have earned 60% in both 'COSC2P12' and 'COSC2P13'.
