Draw this ER Diagram, but  note that: Ths diagram should adhere to compressed Chen notation : The ER diagram consists of four entities: Pet, Challenge, User, and Vote. The Pet entity has attributes such as id (primary key), name, species, age, and description to store information about each pet profile. The Challenge entity has attributes such as id (primary key), pet1_id and pet2_id (foreign keys referencing the Pet entity), start_date, end_date, and likes to store information about each challenge between two pets. The User entity has attributes such as id (primary key), name, and email to store information about users who participate in voting and challenge creation. The Vote entity has attributes such as id (primary key), challenge_id (foreign key referencing the Challenge entity), user_id (foreign key referencing the User entity), and vote to store information about user's vote for a particular challenge.

Discuss database table possibilities for creating subtype relationships. Discuss the considerations that might lead you to choose one design over the others.

Create an Entity Relationship Diagram (ERD) of the normalized version of this table using Visio's crows-foot notation. The ERD should show the PK and FK columns, plus all of the appropriate column attributes (column name, data type/size, null/not null) plus the relationships (with minimum and maximum cardinality) between tables. Requirements: Show the results of the normalization as individual tables Show the FK and PK columns using Visio's notation You must solve the multi-column issue with grades (Hint: This will require a new column) Show the 3-part column definition as noted Show min/max cardinality   Tables are attached

You have been asked to design and implement a database for CTU, which includes 3 entities (tables), as follows: Students Faculty Courses Part 1 Create a Word document that includes the following: Identify at least 3 attributes for each entity, including the following: Student's entity should have an attribute for the program the student is enrolled in. Faculty should have an attribute identifying their rank. Properly identify all of the primary keys (use solid underlines). Create an entity relationship diagram (ERD) from the entities. You may use SmartDraw, Visio, Erwin, or even Word to draw the diagram. Take a screenshot (no need if you use Word), and insert it into the Word document. Part 2 Use Microsoft Access to implement the database that you designed in Part 1, and include the following: Create the Student, Faculty, and Course tables in Access. Add a few instances in each table. Create 2 queries for the following objectives: Find the student names for all students who are in the…

Discuss your database table possibilities for creating subtype relationships.Talk about what you would look for in a design and how it would affect your final selection.

Instructions: In this assignment, you will convert an Entity-Relationship diagram into a set of related tables. Given the following ERD, write the table definitions for the entities displayed below.  You do not have to indicate data types nor “not null” constraints in this lab.  Use the format TableName ( attribute, attribute…attribute).  Designate primary keys with an underline and foreign keys with a broken underline.  To illustrate, the Regions and Countries table definitions have been created for you below the diagram.  Type your answers in this document and upload it to the appropriate Blackboard assignment link by Monday at 11:59 p.m. ET of this module/week. Note that you should read the “Table Conversions Explained” document in your Reading & Study folder.  I created it to help you better understand how ERDs will ultimately be transformed into real tables.   ERD for the Hourglass timekeeping database

ERD

Using the following E-R diagram, create a set of 3NF relations. Create all primary keys and nonkey attributes needed for each entity.
