Which of the following statements corresponds to the second normal form for an entity - relationship model in relational databases? A relationship must have only one key and the attributes můst have simple donains B A relationship must have a Kev, with simple domains for its attributes and all non-key attributes depend entirely on the key C A. A relationship must have a key with static domains for its attributes which all depend on the key e D A relationship must have only one key with all attributes dependent on the key.

LOGICAL DATABASE DESIGN The above EER-Diagram represents a University Library Membership (see Diagram 5). A member can borrow as many books from the library. Derive relations for logical model from the above EER-Diagram. Please identify any primary key or foreign key in the derive relations (if applicable).
Which of the following is a key part of conceptual design in an entity relationship model? This model resolves the many-to-many relationships to multiple one-to-many relationships. This model adds all of the attributes for each entity. This model converts attributes into columns. This model does not depend on the database management software or the hardware used to implement the model.
An attribute is a characteristic or a resource of an entity. To identify a person who maintains medical, student, and fitness club data in different database may the same qualities be applied to an object? Is there a good reason or a bad reason?
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)
Explain how functional dependencies may be used to indicate: • The entity sets student and teacher have a one-to-one relationship set.• Between entity setsstudent and teacher, there is a many-to-one connection set.
What is the difference between a weak and a strong entity set?
What is the link between the main key of a relation and the functional connections between all of its attributes?
By adding a time characteristic, a relation may be turned into a temporal relation, but will the functional linkages be preserved? How is this issue addressed in a database that tracks time periods?

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.…
Please draw an EER diagram for the bank DB system. It requires to design & plan & document a bank system. Your EER model must include supertype and subtypes inheritance associations based on your initial ER model. Relationship constraints and completeness rules (discussed in the EER module) must be included. Requirements: Metadata: define what attributes (data) represent an object (i.e. account type) and data properties (data types, valid range of values, required vs. optional, etc.) Entities (objects): Account owner, dependent (joint family), Checking account, Savings account, Money Market account, loan account, or other banking objects, online account, etc. (suggestion: Define at least 10 entities) Relationships: customer deposit or withdraw money with account, and more. Identify the possible entity sets and their attributes, the relationships among the attributes.
