- 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 attachedInstructions: 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 databaseDraw an ERD & include all the entities, attributes and relationships, PKs and FKs.

- Create an ERD using Visio or any other tool for the following scenario. Your ERD should show all the tables, attributes for each table and identify all primary and foreign keys. A hair salon has many customers and many stylists - the first name, last name, and phone number need to be stored for customers and stylists. The hair salon offers many services - hair cutting, styling, coloring, permanents, etc. Each service has a cost and the estimated time. Customers schedule appointments with a stylist. The appointment can consist of one or more than one service - i.e. a person may want a hair cut and coloring. Some customers purchase products at their appointments. A product has a brand, description, category and price. Please show all work and the finished diagram. Thank you!A.What characteristics do tables that conform to the concept of well-informed relations have? B Describe a dependency diagram and explain its purpose C.
