Task:Let us consider the following relational database. The primary key column(s) of each table is denoted by an underline. The foreign keys are italicized.Schema:▪ Customers (custID, fName, lName, password)▪ Phones (custID, phone)▪ Items (iID, name, price, qtyInStock)▪ OrdersPlaces (oID, ordDate, shippingDate, receivalDate payAmount, payMethod, custID)▪ Contain (oID, iID, price, qty)Specifically, the foreign keys for this database are as follows:• the column custID of relation Phones that references table Customers, • the column custID of relation OrdersPlaces that references table Customers, • the column oID of relation Contain references table OrdersPlaces, and• the column iID of relation Contain references table Items, This is an individual assignment – no group submissions are allowed. Submit a script file that contains the SELECT statements by assigned date. The outline of the script file lists as follows:/*…
Suppose you are given the following requirements for a simple database for the National Hockey League (NHL): • There exists many teams in the NHL • Each team has a teamID, name, a city, a coach, and one or more players • Each player belongs to only one team • Each player has a playerID, name, a position (such as left wing or goalie), a skill level, and a set of zero or more injury records . An injury record has an injuryRecordID, a game, a player, and a description. • A game is played between two teams and has a gameID, a homeTeamID, an away TeamID, a date (such asMay 11th, 2017), a home team score, and an away team score. Construct a schema for this database and ensure all relationships cardinalities (1:1, 1:M, M:M) match the requirements above. Then, using this schema, write your Data Definition Language queries in SQL to be able to create these tables in SQLite. Ensure all relevant constraints (Primary Keys, Foreign Keys, NOT NULL, data types) are included. Submit both the schema…
Q3. Suppose you are given the following business rules to form the basis for a database design. The database must enable the manager of a company dinner club to mail invitations to the club's members, to plan the meals, to keep track of who attends the dinners, and so on. Each dinner serves many members, and each member may attend many dinners. A member receives many invitations, and each invitation is mailed to many members. A dinner is based on a single entree, but an entree may be used as the basis for many dinners. For example, a dinner may be composed of a fish entree, rice, and corn. Or the dinner may be composed of a fish entree, a baked potato, and string beans. Because the manager is not a database expert, the first attempt at creating the database uses the structure shown in the table below: Attribute Name MEMBER_NUM MEMBER_NAME MEMBER_ADDRESS MEMBER_CITY MEMBER_ZIPCODE INVITE_NUM INVITE_DATE ACCEPT_DATE DINNER_DATE DINNER_ATTENDED DINNER_CODE DINNER_DESCRIPTION Sample Value…
A relation r(A, B, C) had multi-valued dependencies among all its attributes. It was decomposed for achieving a better database as follows r1(A, B) r2(B, C) r3(C, A) This is an example of what kind of normalization? BCNF 4NF OPJNF DKN
