Problem Statement: You are the CTO of a startup based out of Arlington, VA that needs to setup a database to keep track of the details of the customers: last name, first name, customer ID, street address, customer star rating (a rating on a 1– 5 scale, with 5 being best, representing the type of customer) and phone number. It also needs to keep track ofsimilar information for suppliers as well (although instead of supplier first and last name, there will just be a suppliercompany name).
The database should maintain the data on products that are offered. Information about whichproduct is offered by which supplier should also be maintained. Finally, which customers have purchased whichproducts should also be tracked (note that we are only interested in which customers bought which product, but notconcerned about the date or how many were bought).
1.1 Business Rules: Assumptions for the business model are as follows:•Only customers that have purchased one or more products will exist in…
What do you need to do if a tutor signs up and wants to tutor in both reading and math? Draw the new ERD, create new relations, and write any SQL statements that would be needed to handle this development.
Write the SQL statements to create all of the necessary tables to represent the above diagram, representing as many constraints as possible. Note: you do not need to worry about specifying types for the fields, but you do need to provide suitable foreign key option(s). When playing a game, the home team name should be stored in attribute htname and the away team name should be stored in atname.

- Create a diagram for a database with at least 5 tables. This should show your table names and column names. Show the relationships between the tables. Write a statement explaining your database design (why did you use the tables that you did). Create a database in Access based on your diagram. Include all tables in your diagram. Tables should each have a minimum of 5 rows. Create 5 SQL statements using your database. At least 2 of these should be manipulation statements (insert, update, etc). The others should be select statements. Explain what your sql statements do and how they would be useful to your database.arrow_forwardTrying to write SQL statements for these shown here and having issues with them working.
