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
Using the ER diagram for Supplier and Part entities provided (attached here), convert the ERD logical design into a physical database using Microsoft Access. Make sure that you have to create both tables, then use "Database Tools"/"Relationship" to set a specific relationship type between two entities. Once you created both tables, type in at least 5 sample records per entity table ( special care needed when you enter sample data in FK field). Perform a Query to obtain "Supplier_ID", "Supplier_Name", "Part_Num", "Part_Name" data from both entity tables. Also create a form and report using any entity
