how to map ERR model to relational model
What are three signals that a surrogate key should be generated for the primary key of a relation instead of using the main key?
Consider the relational schemapart(part_id, name, cost)subpart(part_id, subpart_id, count)where the primary-key attributes are underlined. A tuple (p1, p2, 3) in the subpartrelation denotes that the part with part_id p2 is a direct subpart of the partwith part_id p1, and p1 has 3 copies of p2. Note that p2 may itself have furthersubparts. Write a recursive SQL query that outputs the names of all subparts ofthe part with part-id 'P-100'.
25. In the relational model, relationships between relations or tables are created by using: a. composite keys b. determinants c. candidate keys d. foreign keys
The following Figure 2 shows an EER schema for a database that can be used to track sales at a car dealership. Map this schema into a relational data model, including all primary keys and referential integrity constraints (foreign keys). For the VEHICLE to CAR/TRUCK/SUV generalization, consider the four Step 8 options presented in the lecture notes for mapping specializations/generalizations. Show the relational schema design under each of those four options (8A, 8B, 8C, 8D).

Develop an Entity Relationships Diagram (ERD) based on the relational schemas in the 3NF for the starting relational schema in un-normalized form presented below. UNF:Order(OrderID, OrderDate, CustID, CustName, CustPhone, CCNum, CCExpDate, CCBank, BnkContName, BnkContPhone, CustEmail, OrderIP, SiteRefFrom, ShipStreet, ShipCity, ShipSt, ShipZip, OrderLineNum, ItemID, ItemName, ItemDesc, ItemQtyOrdered,ItemListPrice, ItemSalePrice, ItemQtyShip, ShipCharge, Tax, TotalDue)
Use the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.
Consider the following relational database schema consisting of the four relation schemas:i. passenger (pid, pname, pgender, pcity)ii. agency (aid, aname, acity)iii. flight (fid, fdate, time, src, dest)iv. booking (pid, aid, fid, fdate)Answer the following questions using relational algebra queries;1. Get the complete details of all flights to Kumasi.2. Get the details about all flights from Accra to Kumasi.3. Find the passenger names for passengers who have bookings on at least one flight.
Explain how functional dependencies can be used to indicate the following: A one-to-one relationship set exists between entity sets student and Instructor. A many-to-one relationship set exists between entity sets student and instructor.
Give a Relational Model that corresponds to the Entity-Relationship Diagram given below: address M M Participates 1 Евployee Project Uses Supplier 1 person married to lti is_Harried to City You can present this model as a Relational Database Schema or as a diagram. It must be clearly stated what primary and what foreign keys are and what the foreign keys reference. You may want to use the translation explained in Topic 2.2, but only provide your final result (don't show your working). In your schema you are supposed to use the same names for attributes and relations as given in the diagram.
Convert the ER diagram to relations in the normal manner to capture as many constraints as possible, and then identify which of the answers is a relation schema. A. Dependents(ID, name, bDate) B. Employees(ID, name, street, city, state, phones, sDate, lengthEmp) C. Coverage(ID, name) D. Employees(ID, name, street, city, state, sDate, lengthEmp)
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.…
