Normalise the following relation to remove modification anomalies showing all steps for 1NF, 2NF and 3NF . State any necessary assumptions to support your answer. Important : Provide appropriate justification for each normalisation step.

2. For the following questions, please identify the candidate keys of the given relations. You need to show the process to justify your answers. a) The given relation is R1(ABCDE). The given dependencies are A B B-E C-D b) The given relation is R2(ABCDE). The given dependencies are AB→BCDE BC ACE D-E
Consider a relation named as BOOK that contains data about the books in a library. BOOK relation was initially created with the attributes BookID (an id that library assigns), ISBN, CopyNr (used to differentiate copies of the same book), Title, PublYear, Author, and AuthorBornYear. Primary key: BookID, CopyNr and Author Candidate key: ISBN, CopyNr and Author Below you see dependencies of attributes: Dependency 1 (D1): ISBN, Title, PublYear, AuthorBornYear were dependent on BookID, CopyNr and Author Dependency 2 (D2): Title and PublYear were dependent on BookID, CopyNr Dependency 3 (D3): AuthorBornYear was dependent on Author First determine which normal form (1NF, 2NF, 3NF or BCNF) the above relation is, and why. Then, if necessary, convert the above relation to the highest normal form (BCNF). Write any assumptions that you make.
What are three signals that a surrogate key should be generated for the primary key of a relation instead of using the main key?
For merging two relations that are not physically sorted but share an index on the characteristics in question, it is necessary to develop a hybrid merge-join method.
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)
Primary key identifies a unique tuple of a relation, true or false?
TF (c) If a relation is not in BCNF, then it has at least three attributes in the schema.
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.…
120. Which formal method that locates and analyses relation schemas on the basis of their primary, candidate keys, and the FD’s that are present among the attributes of these schemas: a. Functional dependency b. Database modeling c. Normalization d. Decomposition
Modify the dependency diagrams you created in #1 to produce a set of dependency diagrams that are in 3NF. (Hint: One of your dependency diagrams should be in 3NF but not in BCNF.)
Develop a hybrid merge-join technique for scenarios when both relations are not physically sorted but have a sorted secondary index on the attributes to combine.
