Primary key identifies a unique tuple of a relation, true or false?
To keep track of students and their advisors, a university uses the table structure shown below. Assuming that the sample data are representative, draw a dependency diagram in Visio that shows all functional dependencies including both partial and transitive dependencies. (Hint: Look at the sample values to determine the nature of the relationships.)

create a dependency diagram based on this ERD. Decompose the relation in the resulting dependency diagram into a set of 3NF relation this is introduction to databse system question
Identify the primary key(s)in the table below. Draw as-is dependency diagram and identify types of dependencies. Is this table 3rd normal form? If not, convert it to 3rdnormal form.
Please show the non-trivial functional dependency of the question below: Timesheet (StaffID, FamilyName, OtherNames, TimesheetID, Date, StartTime, EndTime, StoreID, Location, State, RoleCode, RoleName, Rate, Total, TotalPay) please display in functunial dependency notiation. thank you!
Create ERD of a hospital with these requirements "and then" write relation schema (underline primary key and connect foreign key with arrow): (use Chen Notation) 1. Hospital have many department, each department have it's own ID, name, and head of department. 2. Hospital need to collect Patient data included : ID, Name, Sexuality, Age, Address, Health Insurance, Telnum 3, Patient may have data stored about people they can contact, should be more than 1 people they can contact 4. Doctor should have : DocID, Name, Sex, TelNum, Specialty, Years of service, Salary, Qualification 5. 1 doctor can be assigned to only 1 department 6. some doctor may not have their assigned patient 7. patient can be assigned to more than 1 doctor for treatment 8. each treatment shall be stored (date, detail, next appointment) Specification for the diagram: - describe what should be describe and what can be describe inside the diagram - also explain others that can be describe inside the diagram briefly (don't…
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 initial dependency diagram (attached), remove all partial dependencies, draw the new dependency diagrams in Visio, and identify the normal forms for each table structure you created. **Original table structure with data is attached
For each of the following relations, indicate the normal form for that relation. If the relation is not in third normal form, decompose it into 3NF relations. Functional dependencies are shown where appropriate. a) CLASS(CourseNo, SectionNo) b) CLASS(CourseNo, SectionNo, Room) c) CLASS(CourseNo, SectionNo, Room, Capacity) d) CLASS(CourseNo, SectionNo, CourseName, Room, Capacity)
Kindly find attached. Normalize the relations into first, second, and third normal form. First, describe the changes required to your relations to meet the standard of first 1NF and then 2NF and lastly 3NF. Then, you should provide an Entity Relationship diagram that is in 3NF. All attributes, entities, keys, and relationships should be included and labeled. Hint: (Attached)Remember that in the hospital software system, the “Patient” relation includes “medicines” attribute and the “Appointment” relation includes “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient. It should define or describe the changes required to get the relations into the 1st normal form. It should define or describe the changes required to get the relations into the 2nd normal form. It should include an Entity Relationship diagram in the 3rd normal form. The primary and foreign keys, at a minimum, are defined for each…
3. a) A relation that does not have a composite primary key still has partial functional dependency. A) TRUE B) FALSE If you choose “False”, please explain below why it is “False. 3. b) For a table to be in 2NF, both of the following must be true: 1) this table that must be in 1NF and 2) this table must have no partial functional dependencies. TRUE FALSE If you choose “False”, please explain below why it is “False.” 3. c) A relation that is in 1NF must be in 3NF if the primary key consists of only one attribute. TRUE FALSE If you choose “False”, please explain below why it is “False.”
Candidate key is an attribute or set of attributes that uniquely identifies a tuple within a relation. Integrity constraints is to make sure that the data is accurate. Staff number in a staff table is a multiple attribute. A weak entity is an entity that is existence-independent. jgive answer true or false
