When translating an ER model into database tables a.) all of the entity attributes become the foreign keys. b.) the entity attributes become the tables. c.) for each entity, two tables need to be created. d.) the entity attributes become the fields of the new table. The goal of normalization is to, (please select all that apply): a.) eliminate data duplication. b.) is create only 1:N relationships. c.) to create as few as possible tables to promote efficiency between the tables. d.) construct tables so that each table has a single topic or theme.
CHAPTER 9 Using cardinalities shown in the partial ER diagram, name the Foreign Key(s) (FK) that should be placed into the respective tables. If no foreign key is required in a table, then indicate NONE. Add any table(s) and Keys that may be needed
For each table, identify the primary key and the foreign key(s). If a table does not have a foreign key, write None in the space provided. Do the tables exhibit entity integrity and referential integrity? Answer yes or no and then explain your answer. In the case of Referential Integrity write NA (Not Applicable) if the table does not have a foreign key. iii. Describe the type(s) of relationship(s) between STORE and REGION Create the ERD to show the relationship between STORE and REGION.6 Describe the type(s) of relationship(s) between EMPLOYEE and STORE. (Hint: Each store employs many employees, one of whom manages the store.) Draw the ERD to show the relationships among EMPLOYEE, STORE and REGION.
What reasons do constraints assist a business? From a business standpoint, what can occur if you don’t create a primary and related foreign keys? Refer to the KimTay Pet Supplies database. What business concerns could arise if CUST_ID isn’t a foreign key in the INVOICES table? What concerns are there if is there is not a CHECK constraint on the CATEGORY field in the ITEM table?

Consider the following relations about NBA: P LAY ER(pid, pname, nation). Each tuple describes a player with pid being the player’sid, pname his name, and nation his nationality. The table has a primary key pid. T EAM(tid, tname). Each tuple describes a team with tid being the team’s id, and tnameits name. The table has a primary key tid. REGIST ER(pid, tid, salary, year). Each tuple records the fact that a certain player (indicated by pid) played for a certain team (indicated by tid) in a specific year with an annual income given in salary. The table has a primary key (pid,year ). Note that a player may belong to different teams in different years. (a) Find the names of the teams and the corresponding year that “Michael Jordan” ever playedfor. (b) Find the names of all players of the team “Heat” in year 2020. (c) For each player, display his pid, and the first and last years in which he played. (d) Find the pids of all players that played from 2010 through 2020 (i.e., such a…
Examine the table shown below. (In the pictures) staffNo and branchNo are the composite primary key pair of the table. Deduce the following: a) Identify the Normal Form of the Table? Mention step by step reasoning. b) Describe and illustrate the process of normalizing the data shown in this table to third normal form (3NF)? Basically, design the tables with their attributes and keys which will be formed because of the tables converted to achieve 3NF. Show the resulting tables below. You can use crows foot notation if needed to display the tables. Displaying data is not mandatory. Proper display of the resulting #NF normalized Table Schema is what is needed.

3. The QR table records the workshop attendance of students. The BB table is a master table that holds student’s data in INFO151. The ZOOM table automatically records students who enter the workshop session with zoom. The requirements for each of the tables are listed in the requirement table below. (a) Write the DDL to create the tables with the suggested attributes, data types and constraints. (b) What is a composite key? Is the primary key in the BB table a composite key or a surrogate key? Must the last name be unique for this type of primary key? (c) Discuss the limitation of using FName and LName as the primary key. (d) Is the relationship between BB and QR tables a one-to-one? If it is not, state the correct relationship.
