Draw the Entity- Relationship Diagram (ERD) for the following scenario: o Galleries keep information about artists, their names (which are unique), birthplaces, ages, and styles of art. For each piece of artwork, the artist, the year it was made, its unique title, its type of art (e.g., painting, lithograph, sculpture, photograph), and its price must be stored. o Pieces of artwork are also classified into groups of various kinds, for example, portraits, still live, works by Picasso, or works of the 19th century; a given piece may belong to more than one group. o Each group is identified by a name (like those just given) that describes the group. Finally, galleries keep information about customers. For each customer, galleries keep that person's unique name, address, the total amount of dollars spent in the gallery (very important!), and the artists and groups of art that the customer tends to like. Construct a clean and concise ER diagram for this database using he UML notation.

→ Draw the Entity- Relationship Diagram (ERD) for the following
scenario:
o Galleries keep information about artists, their names (which are
unique), birthplaces, ages, and styles of art. For each piece of
artwork, the artist, the year it was made, its unique title, its type of
art (e.g., painting, lithograph, sculpture, photograph), and its price
must be stored.
o Pieces of artwork are also classified into groups of various kinds,
for example, portraits, still live, works by Picasso, or works of the
19th century; a given piece may belong to more than one group.
o Each group is identified by a name (like those just given) that
describes the group. Finally, galleries keep information about
customers. For each customer, galleries keep that person's
unique name, address, the total amount of dollars spent in the
gallery (very important!), and the artists and groups of art that the
customer tends to like.
