im new to this stuff so i was wondering if i did this right i upload a document on what i have done Pick and Shovel Construction Company is a multi-state building contractor specializing in medium priced town homes. Assume that Pick and Shovel's main entities are its customers, employees, projects and equipment. A customer can hire the company for more than one project, and employees sometimes work on more than one project at a time. Equipment, however, is assigned to only one project at a time. Draw an ERD showing those entities.
