Pet Database Design

ABC apartments has a one pet limit per apartment and they charge a nonrefundable deposit for the pet.  ABC wants to retain information about each pet and where it lives.  They do not allow a pet to be shared between apartments (in other words, a pet can’t live in different apartments).  So the rules for ABC are that an apartment may only have one pet and a pet may only live in one apartment.  Draw an ER Diagram for this model.  Then map you ER Diagram to a set of tables.  Be sure to include a reasonable set of attributes (ie. ApartmentNo, ApartmentBldg, PetID, PetName…)

Recipe & Ingredients Database Design

A recipe is made up of many ingredients but those ingredients may also be used in many different recipes.  Recipes have a have a recipe number, recipe name [and many other attributes which you do not need to show].  Ingredients have an Ingredient id and ingredient name [and many other attributes you do not need to show].  Draw the ER Diagram and Map to Tables

Actors and Play Database Design

Actors act in Broadway Plays.  But an actor must have a contract that specifies their start date and salary before they can perform in the play.  Each actor has a unique Screen Actors Guild number.  Other data kept about an actor includes name, age and gender.  Plays have a name and genre.  Draw the ER Diagram and then map the diagram to a set of tables

KSU Volleyball Team Database Design

The KSU Volleyball team needs to maintain information about teams they play and the players on those teams.  A team is made up of many players.  Teams are known by their team number and team name.  Players are assigned an Id and a position and are also known by their name.  The ER Diagram is shown
