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 home TeamID, 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 diagram and a .sql file containing all of your create table queries.

Suppose we have a database for an university. The requirements are as follows: • Professors have an SSN, a name, an age, a rank, and a research specialty. • Projects have a project number, a sponsor name (e.g., NSF), a starting date, an ending date, and a budget. • Graduate students have an SSN, a name, an age, and a degree program (e.g., M.S. or Ph.D.). • Each project is managed by one professor (known as the project’s principal investigator). • Each project is worked on by one or more professors (known as the project’s co-investigators). • Professors can manage and/or work on multiple projects. • Each project is worked on by one or more graduate students (known as the project’s research assistants). • When graduate students work on a project, a professor must supervise their work on the project. Graduate students can work on multiple projects, in which case they will have a (potentially different) supervisor for each one. The FDs for the above requirements are given as, • PSSN →…

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. Draw the Crow’s Foot ERD to reflect the dependency diagrams you drew in Part c. (Note: You might have to create additional attributes to define the proper PKs and FKs. Make sure that all of your attributes conform to the naming conventions.)
