What is the relationship between the Third Normal Form (3NF) and the Boyce Codd Normal Form (BCNF)? (a) 3NF and BCNF are equivalent. (b) If a schema is in 3NF, it is also in BCNF. (c) If a schema is in BCNF, it is also in 3NF. (d) If a schema is in 3NF, it is not in BCNF. (e) none of the above.

Discuss the classification of traceability relations; elicit a brief example that describes the classification context;

What exactly is meant by the abbreviation "ADT" (which stands for "Abstract Data Type")? What are some of the benefits of using ADTs? How exactly does the concept of heredity contribute to the process of finding solutions to problems?

Consider a relational schema R = {A, B, C, D, E, G, H}, satisfying the functional dependencies F = {E → G, E → H, G → H, A → BC, BC → D, C → H, EG → A}. a) Derive all candidate keys for this schema. b) Derive a canonical cover of the functional dependencies in F. c) Is the above schema in BCNF? Prove or disprove. If it is not in BCNF, convert it into BCNF. d) Is the BCNF schema from (c) dependency-preserving? Prove or disprove. If not, convert into 3NF.

If the issue set consists entirely of nominal characteristics, a vector space-based classification approach is not the best option. Please share your thoughts on this assertion. How would you apply ML to the task of categorizing nominal data?

What is the difference between a weak and a strong entity set?

A three-schema design has three levels, and at each level, requests are turned into results.

Investigate the benefits and drawbacks of snowflake and star schemas. Which is less normalized than the other?

Produce a relational schema diagram that corresponds to the linked ER diagram for a database for the television show Saturday Night Live (SNL). Your relational schema diagram should include primary and foreign keys. Often-times in database system development, requirements will change after the conceptual data model has been drafted: in your rela- tional schema diagram, add the following three additional attributes: attribute “birth.date" for the relation schema Host; attribute “start.date" for the relation schema Writer; and attribute “salary" for relation schema Cast Member. Please refer back to the requirements in Question 6, for additional details that may constrain the design of the relational schema model. Use the tool linked to create an image. Hints: please carefully note that "rerun date", “address", and “phone" are multi-valued attributes; how would those be depicted in the relational schema diagram? Also, please carefully note the many-to-many relationships; how would those…

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information.   Remember the ERD will eventually turn into the design for a database from a top down view.  Make sure you resolve any many to many conflicts.  Label an identifier or primary key and all pertinent attributes given.   If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity.  Therefore, all entities should end up with at least an identifier and another attribute that makes sense.  You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common.  Make sure you show entities, relationships, cardinality, and optionality.  Swing Jazz Club The Swing Jazz Club teaches swing and jazz dancing and offers both private and group lessons.  Swing Jazz charges $60 dollars per hour for a private lesson and $10 dollars per hour for a group lesson.…
