- (a) Given the following method header: public boolean addMovie(Movie movie) Complete the implementation of the method above to insert a new movie into the Movies table in thedatabase. Your method should return true if an insert is successful, and false if an insert fails. You candetect a successful insert through the number of rows returned after the execution of a query. UsePreparedStatement in your answer and include the appropriate exception handling. The Movie classand database table structure specifications are shown in Figure 2.1 and Figure 2.2 below:which object can be used to speed up searches and quires in general? a) Index b) Unique c) Check d) CascadeCreate a Client class that interacts with an SQLDatabase Server (provided below). The Client sends a SQLQuery to the SQLDatabase and receives a Dataframe from the SQLDatabase. The class should contain the default __dunders__ and potentially introduce some custom __dunders__. The SQLDatabase Server: import pandas as pd import sqlite3 class Server: def __init__(self, database): self.conn = sqlite3.connect(database) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.conn.close() def __repr__(self): return f"Server({self.conn})" def execute_query(self, query): cursor = self.conn.cursor() cursor.execute(query) columns = [desc[0] for desc in cursor.description] results = cursor.fetchall() df = pd.DataFrame(results, columns=columns) cursor.close() return df

Design a Server Class that provides access to a SQLDatabase. The clients of your SQLDatabase server, send an SQLQuery to the SQLDatabase.
