Questiоns 32 thrоugh 35 relаte tо the following ER diаgrаm. Data domain definitions for the attributes are given below. Attribute Description Domain Nurse ID Set of possible nurse IDs Fixed Character: size 5 Nurse Name Set of possible nurse names Variable Character: size 20 Nurse Birth Date Set of possible nurse birth dates Date Date Assigned Set of possible assignment dates Date Center ID Set of possible care center IDs Number: size 4 (no decimal) Center Location Set of possible care center locations Variable Character: size 10 (This column can only take one of three values: Dallas, Plano, Allen) Based on the conceptual model and the domain definitions, we decided to create tables using SQL DDL statements for NURSE and CARE CENTER relations to build the database. We came up with the following table definitions (based on the relational schema, which is not shown here). CREATE TABLE Nurse_T (NurseID A,NurseName B,NurseBirthDate C, CONSTRAINT Nurse_PK D );CREATE TABLE CareCenter_T (CenterID E,CenterLocation F, CONSTRAINT CareCenter_PK G ); Which of the following SQL DDL code should be inserted in place of ‘F’?
Questiоns 5 thrоugh 9 relаte tо the following scenаrio. Suppose thаt you are asked to create an ER diagram for a real estate firm that lists properties for sale. The following rules describe the data requirements for this firm. The firm has a number of sales offices in several states. Attributes of a sales office include Office Number (identifier) and Location. Each sales office is assigned one or more employees. Attributes of employee include Employee ID (identifier) and Employee Name. An employee must be assigned to only one sales office. For each sales office, there is always one employee assigned to manage that office. An employee may manage only the sales office to which he or she is assigned. The firm lists properties for sale. Attributes of property include Property ID (identifier) and Location. Components of Location include City, State, and Zip Code. Each unit of property must be listed with one (and only one) of the sales offices. A sales office may have any number properties listed or may have no property listed. Each unit of property has one or more owners. Attributes of owners are Owner ID (identifier) and Owner Name. An owner owns one or more units of property. Attribute Percent Owned represents ownership percentage of a property by an owner. Assume that you drew the draft ER diagram for this real estate firm below. However, this solution is neither complete nor fully correct. Please answer the questions related to this draft solution. Consider the Owns relationship between OWNER and PROPERTY entities. Which of the following cardinalities are missing in this relationship?
