Input: Article: A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase, SAP HANA, and IBM DB2. A database is not generally portable across different DBMSs, but different DBMS can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language.[disputed discuss] Sometimes a DBMS is loosely referred to as a 'database'.

Now answer this question: How are DBMSs classified?

Output: according to the database model that they support

Input: Article: During the fighting, the Communards killed c.500 people, including the Archbishop of Paris, and burned down many government buildings, including the Tuileries Palace and the Hotel de Ville. Communards captured with weapons were routinely shot by the army and Government troops killed from 7,00030,000 Communards in the fighting and in massacres of men, women, and children during and after the Commune. More recent histories, based on studies of the number buried in Paris cemeteries and in mass graves after the fall of the Commune, put the number killed at between 6,000 and 10,000. Twenty-six courts were established to try more than 40,000 people who had been arrested, which took until 1875 and imposed 95 death sentences, of which 23 were inflicted. Forced labour for life was imposed on 251 people, 1,160 people were transported to "a fortified place" and 3,417 people were transported. About 20,000 Communards were held in prison hulks until released in 1872 and a great many Communards fled abroad to England, Switzerland, Belgium or the United States. The survivors were amnestied by a bill introduced by Gambetta in 1880 and allowed to return.

Now answer this question: What is the rough estimate of the number of people killed?

Output: between 6,000 and 10,000

Input: Article: Unlike the above antennas, traveling wave antennas are nonresonant so they have inherently broad bandwidth. They are typically wire antennas multiple wavelengths long, through which the voltage and current waves travel in one direction, instead of bouncing back and forth to form standing waves as in resonant antennas. They have linear polarization (except for the helical antenna). Unidirectional traveling wave antennas are terminated by a resistor at one end equal to the antenna's characteristic resistance, to absorb the waves from one direction. This makes them inefficient as transmitting antennas.

Now answer this question: What antenna's are nonresonant?

Output:
traveling wave antennas
