Mình có bài tập sau bằng tiếng anh, mọi người cùng giúp nhau nghiên cưu mổ xẻ để hiểu thêm về USE CASE Diagram và viêt USE CASE DESCRIPTION nhé:

A Real Estate Inc. (AREI)

A Real Estate Inc. (AREI) sells houses. People who want to sell their houses sign a contract with AREI, and provide information on their house (street address, postcode, number of bedrooms, type of house1, and price). The information on the house and the seller (name, street address, postcode, and bank details) is kept in a database by AREI. The information on the house for sale is sent to the citywide multiple listing service used by all real estate agents.

AREI works with two types of potential buyers. Some buyers have interest in one specific house. In this case, AREI prints information from its database, which the real estate agent uses to help show the house to the buyer (a process beyond the scope of the system to be modelled). Other buyers seek AREI’s advice in finding a house that meets their needs. In this case, the buyer completes a buyer information form including the buyer’s details (name, street address, and postcode) as well as details defining houses that might be of interest (possible postcodes, number of bedrooms, types of houses, and budget). The information on the buyer and his/her interests are entered into a buyer database. AREI real estate agents use the information on the buyer’s interests to search AREI’s database and the multiple listing service for houses that meet their needs. The results of their searches are printed and used to help the real estate agent show houses to the buyer.

Every two weeks, AREI’s software system generates a report informing the AREI real estate agents of any new properties that have entered the market and might be of interest to their enrolled existing potential buyers (i.e., buyers in their database with a profile that matches the new houses’ descriptions). These matching searches are also performed every time that a new house is put up for sale with AREI and/or there is a change in the interests of an enrolled potential buyer.

Mọi người cùng tham khảo và thức hành nhé.

Nếu có ai có phần giải ròi thì cùng share lên với mọi người, mình cũng đang tập vẽ, khi nào xong thì mình sẽ up lên để mọi người cùng nghiên cứu (^^)
