First, why do organizations create multiple databases, not just one all-inclusive database supporting all data processing needs? Second, what organizational and personal factors are at work that might lead an organization to have multiple, independently managed databases (and, hence, not completely follow the database approach)?Database Management Systems (DBMSs) are specially designed applications that interact with the user, other applications, and the database itself to capture and analyze data.

People who want to sell their houses sign a contract with CRE and provide information on their house such as the current owner’s SSN, the owner’s name, the address of the house, the number of rooms, the number of baths, and the square feet of the house to a staff of CRE who is responsible for the management of house information. Then, the information is entered into the database by the staff of CRE. This information is kept in a database and a subset of this information is sent to the citywide multiple listing service used by all real estate agents. CRE works with two types of potential buyers. Some buyers have an interest in one specific house. In this case, advising specialists of CRE (advising specialists don’t manage the house information) print information from its database, which the advising specialists use to help show the house to the buyer.
