For the following problem: You need to design database for managing the task assignment in a work order. A work order records a set of tasks requested by a customer at a specific location: - A customer has a unique customer identifier, a name, a billing address (street, city, state and zip), and a collection of submitted work orders. - A work order has a unique work order number, a creation date, a date required, a completion date, a customer, an optional supervising employee, a work address (street, city, state and zip) and a set of tasks. - Each task has a unique task identifier, a task name, an hourly rate, and estimated hours. A task can be performed on many work orders. - Each task on a work order has a status (not started, in progress, or completed), actual hours and a completion date. 1) Draw the E-R diagram using the Crowfoot notation. Show the minimum and maximum cardinality for each relevant entity-entity relationship and determine the possible keys for each entity. 2) Based on your diagram from 1) describe the relationships that cannot be implemented using the Relational Database model. 3) Propose a new design that will resolve the issues found
