Kindly find attached. Normalize the relations into first, second, and third normal form. First, describe the changes required to your relations to meet the standard of 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 labeled. Hint: (Attached)Remember that in the hospital software system, the “Patient” relation includes “medicines” attribute and the “Appointment” relation includes “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient. It should define or describe the changes required to get the relations into the 1st normal form. It should define or describe the changes required to get the relations into the 2nd normal form. It should include an Entity Relationship diagram in the 3rd normal form. The primary and foreign keys, at a minimum, are defined for each…
Justify how the main key of a relation is connected to all of the qualities of the relationship in issue, as well as the functional dependencies that exist among all of those features.
Explain the relationship between the primary key of a relation and the functional dependencies that exist between all of the characteristics in the relationship under consideration.
Explain the connection between a relation's primary key and the functional dependencies that exist between all of the characteristics in the relationship in question.
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)
Q3: Define a relation prereq depth(course id, prereq id, depth) where the attribute depth indicates how many levels of intermediate prerequisites there are between the course and the prerequisite. Direct prerequisites have a depth of 0. Note that a prerequisite course may have multiple depths and thus may appear more than once.
A subtype/supertype relationships are especially important in Enhanced Entity Relationship Modeling. Explain using an example how you would covert subtype/supertype relationships to relations in database design.
Candidate key is an attribute or set of attributes that uniquely identifies a tuple within a relation. Integrity constraints is to make sure that the data is accurate. Staff number in a staff table is a multiple attribute. A weak entity is an entity that is existence-independent. jgive answer true or false
Map the ER diagram below to a set of relations (i.e., relational schema). Underline the primary key attributes of each relation. Indicate referential integrity constraints using arrows. An arrow from an attribute A to an attribute B represents that A references
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…
Design an Entity-Relationship for each system described below. Use the (min,max) notation. State clearly any additional assumptions you make. Give the relational model by applying the mapping rules (WITH REFERENCES AND ARROWS). NOTE: USE CHEN ER DIAGRAM (YOU CAN USE VISIO MICROSOFT(TEMPLATE=CHEN) ONLY SHOWING THE ENTITIES/ATTRIBUTES/WEAK ENTITIES/RELATIONSHIPS/PRIMARY KEY-FK/ (MIN-MAX) NOTATIONS ALSO NOT FORGETTING THE REFERENCES ON THE MAPPING TABLES WITH ARROWS REFERRING THE FOREIGN KEYS. YOUR WORK SHOULD BE SPECIFIC WITH JUSTIFICATION. We want to build a database for a community of paleontologists, storing information about the fossils kept in different museums. Each fossil is described by the year and place of discovery, the name of the paleontologist who discovered it, the room where it is exposed, and the presumed species. Each fossil may be assigned to different species with different degrees of probability. Museums are characterized by their rooms, their paleontologists and…
Note: Please make sure that all the points/rules must be implemented.Draw the ERD Diagram to create relational model corresponding to the described Scenario. The loan office in a bank receives from various parties, requests to investigate the credit status of aCustomers. Each credit request is identified by a Request ID and is described by a Request Date andRequesting party Name. The loan office also received results of credit checks. A credit check is identifiedBy a credit check ID and is described by the credit check Date and the credit rating. The loan officeMatches credit requests with credit check results. A credit request may be recorded before its resultArrives; a particular credit result may be used in support of several credit requests. Draw ERD for thisSituation. Requirements:ER Diagram of system implemented in tool such as Sqlyog & Draw.io (Available online).
