- Question: Draw a diagram showing the relationships for all the tables. The following tables need to be modified as shown (primary key attributes are bold, foreign key attributes are in italics): CID in Retail and Wholesale are defined as a primary key and a foreign key. CUSTOMER (CID, Name, Address) PHONE (PhoneNumber, Description, CID) RETAIL (CID, Type) WHOLESALE (CID, ContractID) CONTRACT (ContractID, Description) OLDCONTRACT (ContractID, Description) ORDER (OID, OrderDate, CID) PRODUCT (PID, Name, Price) DIVISION (DID, Name, Address) LINEITEM (OID, PID, Quantity, AmountCharged) PRODUCTION (DID, PID, Quantity, Rating) One-to-one Relationship If the foreign key will be the primary key or part of the primary key, choose the Identifying Relationship 1:1 icon. Otherwise, choose the Non-Identifying Relationship 1:1 icon.arrow_forwardPlease draw an Entity-Relationship diagram for the given below MOVIE database. The data requirements are summarized as follows: Each movie is identified by title and year of release. Each movie has a length in minutes. Each has a production company, and each is classified under one or more genres (such as horror, action, drama, and so forth). Each movie has one or more directors and one or more actors appear in it. Each movie also has a plot outline. Finally, each movie has zero or more quotable quotes, each of which is spoken by a particular actor appearing in the movie. Actors are identified by name and date of birth and appear in one or more movies. Each actor has a role in the movie. Directors are also identified by name and date of birth and direct one or more movies. It is possible for a director to act in a movie (including one that he or she may also direct). Production companies are identified by name and each has an address. A production company produces one or more movies.arrow_forwardFor each of the following E-R diagrams transform the diagram to a relational schema (draw the graphical notation).

- Please help me do this senario relationships analysis for the senario below. I have attached them below. Please leave you email as well so if I like your work I can contact you on it.arrow_forwardThe entity type STUDENT has the following attributes: Student Name, Address, Phone, Age, Activity, and No of Years. Activity represents some campus-based student activity, and No of Years represents the number of years the student has engaged in this activity. A given student may engage in more than one activity. Draw an ERD for this situation. What attribute or attributes did you designate as the identifier for the STUDENT entity? Why?arrow_forwardConvert the given ER diagram to Relational Schema.

- 4-44. Figure 4-35 shows an EER diagram for Vacation Property Rentals. This organization rents preferred properties in several states. As shown in the figure, there are two basic types of properties: beach properties and mountain properties. Transform the EER diagram to a set of relations and develop a relational schema. Diagram the functional dependencies and determine the normal form for each relation. Convert all relations to third normal form, if necessary, and draw a revised relational schema. Suggest an integrity constraint that would ensure that no property is rented twice during the same time interval.arrow_forwardUsing the following E-R diagram, create a set of 3NF relations. Create all primary keys and nonkey attributes needed for each entity.arrow_forwardDraw an Entity Relationship Diagram (ERD) based on the flat files that have been supplied.

- Using the relations ATTACHED, normalize your relations into first, second, and third normal forms. First, KINDLY describe the changes required to your relations to meet the standard of the 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 labelled. Hint: Remember that in the hospital software system, the “Patient” relation includes the “medicines” attribute and the “Appointment” relation includes the “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient. Please add: Define or describe the changes required to get the relations into the 1st normal form. Define or describe the changes required to get the relations into the 2nd normal form. Include an Entity Relationship diagram in the 3rd normal form. The primary and foreign keys, at a minimum, are defined for each…arrow_forwardConvert the Entity Relationship Diagram in to Q1. relational database by using MS Access (Note: Students has to create tables in the MS Access by giving appropriate Primary key and Foreign key relationships) Customer Order OrderDetail OrderID OrderDetaillD CustomerID OrderID (FK) Name Mail CustomerID (FK) OrderDate TotalPrice ProductID (FK) ZipCode Address Telephone Amount Price Product ProductID Name Kind Pricearrow_forwardConsider the given ER Diagram for Notown database in Figure 2. You have been tasked to recommend that Notown use a relational database system to store company data. Show the Structured Query Language (SQL) statements for creating relations corresponding to the entity sets and relationship sets in your design. Identify any constraints in the ER Diagram that you are unable to capture in the SQL statements and briefly explain why you could not express them.arrow_forward
