Consider the following relational scheme: X1 A1 A2 X2 АЗ А4 A5 The attributes that are part of the primary key are underlined and shaded. Assume that Following functional dependencies exist: (а) X1, X2 > A1, A2, А3, А4, A5 () X1, —» А1, АЗ, А4 (c) X2 - A2, and (d) A4 + A1. Does this scheme abide by 1st, 2nd, and 3rd Normal Forms? If not, please show the table(s) after each phase.

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.
Consider the universal relation: R = (A, B, C, D, E, F, G, H, I, J) and the set of functional dependencies: A, B -> C B, D -> E, F A, D -> G, H A -> I H -> J What is the key for R? And Decompose R into 2NF, and then into 3NF relations.

Super store have same products of different companies. In the end client received a receipt of their purchase from counter he/she go for bill. Database also save records of stock according to FIFO system. Required to define Entities and their attributes Attributes Types Each Attribute Required Define keys of each entity Define relationship between the entities.
Question 20 Please fill in the blank correctly.
Relations describe the intersection between two axes, x and y. For example, a table (tuple) found in a database contains columns (attributes) and rows (records or observations). Database and Geospatial Mapping Application developers rely on tables and cartesian coordinate systems to adhere to the rules of relational database theory so that integrity in the location is preserved. Tables should only contain records that relate to the columns found in that table and the data domain determines what records should be stored in a given table. Database administrators can check for integrity in relationships within and between tables using structured query language (SQL). What other computer-science or IT jobs rely on relations?

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.
