1. WellDone, Inc.: Well Done (WD) is a regional contractor of real estate development work, such as landscaping, building renovation, and house construction. To manage its growing business and data, WD has recently created a relational database using MySQL. You are helping WD to develop this database. After interviewing the stakeholders and analyzing the current databases, you identified these requirements: A. Each customer is identified by CustomerID, and has the attributes LastName, FirstName, PhoneNo, and BudgetAmt. B. Each contract is identified by ContractNum, and has the attributes Title, and Terms. C. Each customer is associated with one-to-many contracts; each contract is associated with exactly one customer. D. Each invoice is identified by InvoiceNum, and has the attributes InvoiceDate, Invoiceltem, and InvoiceAmt. E. Each contract is paid by zero-to-many invoices; each invoice is used to pay exactly one contract. Write MySQL statements to create the tables to store data for the aforementioned situation. Ensure that the statements are in proper order and meet the stated requirements (use suitable data types as needed). Execute these statements in your personal database in the MySQL server. 2. Write a MySQL statement to add a new attribute named "Email" to the table that stores customer data. 3. Write a MySQL statement to modify the name of the attribute "Title" to "Contract Title" in the table that stores contract data. 4. Write MySQL statements to insert at least three records per table. You may make up the data in a
