Consider a database that records information for a law firm:

• Each case handled by the firm has a unique case number; a date opened, date closed and judgment description are also kept on each case.
• A case is brought by one or more plaintiffs and the same plaintiff may the involved in man cases

A plaintiff has a requested judgment characteristic.

A case is against one or more defendants and the same defendant may be involved in many cases.

A plaintiff or defendant may be a person or an organization. Over time, the same person or organization may be a defendant or a plaintiff in cases. In either situation, such legal entities are identified by an entity number, and other attributes are name and net worth.

1. Draw the E-R diagram
2. Convert the E-R diagram to a relational database schema

please draw the diagram for both of them in a good way.
