Draw an ER diagram for the following scenario:
A designer has a store of designer dresses both for male and female.
People can buy as well as take dresses on rent from the store.
Each dress in the designer's store, is identified by unique ID.
A dress in the store can be categorized into various categories Western, Indian, Indo-westem, etc.
The designer maintains the name, phone number of people who have taken dresses on rent.
The designer also maintains the name, phone number, and address of people who have bought dresses from the store.
The designer also collects feedback from the people who have bought or taken dresses on rent from the store.
Design the ER diagram by mentioning all the structural constraints. You may also include additional information in addition to the requirements listed.

Order: has one or many items; half by member half by anonymous member (no member number)Has: order number, each order item has total cost (with and without gst), number of store, cashier who took the order, member number (if provided), date on which the order was places, and, if the order is not picked up in-person, the date on which the order is shipped.
Order-Item (one of the 1600 products):to identify: useorder number as well as a small “item sequence number” (which is unique within each order). product number, quantity ordered and the actial "unit price paid" If a valid member number is on the order, the system should use the product’s special “member price”, otherwise the product’s “regular price” is used. The average order includes 11 distinct order-items.

- Entity-Relationship Diagrams (ERD) Background Information: Study the following statements to determine the relationship between the entities • Each student has an academic advisor. An academic advisor can advise many students. • Each academic advisor has a specific parking spot assigned. • Each student can take up to five courses. and each course has up to 24 students. • Several adjunct faculty members share an office. Tasks: 1. Draw an ERD (it is just one diagram) showing the entities and the relationships among them. Include associative entities, if any. Also, remember to show cardinality (1:1, 1:M, M:N); you can use the cardinality notation or the crow’s foot notation. Remember that this is a graphical language, and you must follow the shapes of the elements in the diagram.arrow_forwardDesign: An (ER) and (relational Diagram) by showing as I am an owner of a car rental company website describing the following domain: I am the owner of the website, and I see the registered customers records I have through different car types and car rental Every rental operation has a start or end by day or KM Every car has a different price depending on its year production and model We have three rental types( Per Kilometers, monthly, daily) in different prices even though it was the same car Any one can enter his 'id' which includes ( Name, age, gender, address, city, Civil id), and this 'id' is the primary ket to all entities He would proceed to register for renting a car per his choice Then he will send the registrations form that I will analyze and contact him Every customer can rent only one car This choice has one car rental type based on the available listed cars in the registration The owner of that website has the "id" records and the registration database running its…arrow_forwarddescribe each diagram.arrow_forward
