Here is some information about MARLBORO HOMES INC:

An engineering firm named MARLBORO HOMES INC provides design and build services to government and private organizations. The weekly Sales Report and the Customer List Report are shown below. There are six tables required to support these two reports.

Note that there is a Many-to-Many relationship between INVOICE and EQUIPMENT. One invoice can have more than one piece of equipment and that one particular piece of equipment can appear on more than one invoice. For example: Invoice number M-44720 has Equipment numbers P100 and CMT22. Also note that Equipment number P100 appears on Invoice M-44720 and M-44721.

The Weekly Sales Report shows the Customer number which relates to a CUSTOMER table with attributes that are shown on the Customer Report. Any particular GST_LicenseNumber can occur only once in the CUSTOMER table as every customer must have a different GST_LicenseNumber. The only attributes that can be skipped are CustAddress and CustPhone and InvoiceDate. If InvoiceDate is skipped, the system will insert today’s date. The system inserts blanks into SalesPersonName when skipped. GST_LicenseNumber must be greater than or equal to 100000000 and less than 999999999.
