Input: Database
The first task of a database designer is to produce a conceptual data model that reflects the structure of the information to be held in the database. A common approach to this is to develop an entity-relationship model, often with the aid of drawing tools. Another popular approach is the Unified Modeling Language. A successful data model will accurately reflect the possible state of the external world being modeled: for example, if people can have more than one phone number, it will allow this information to be captured. Designing a good conceptual data model requires a good understanding of the application domain; it typically involves asking deep questions about the things of interest to an organisation, like "can a customer also be a supplier?", or "if a product is sold with two different forms of packaging, are those the same product or different products?", or "if a plane flies from New York to Dubai via Frankfurt, is that one flight or two (or maybe even three)?". The answers to these questions establish definitions of the terminology used for entities (customers, products, flights, flight segments) and their relationships and attributes.

Asking questions about an organization's needs will help to create what?
Output: definitions of the terminology used for entities

Input: Antenna (radio)
Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).

If you were unable to choose the antenna you wanted how could you still achieve this result?
Output: matching network

Input: Heian period
The Fujiwara controlled the throne until the reign of Emperor Go-Sanjō (1068-1073), the first emperor not born of a Fujiwara mother since the ninth century. Go-Sanjo, determined to restore imperial control through strong personal rule, implemented reforms to curb Fujiwara influence. He also established an office to compile and validate estate records with the aim of reasserting central control. Many shōen were not properly certified, and large landholders, like the Fujiwara, felt threatened with the loss of their lands. Go-Sanjo also established the In-no-cho (ja:院庁 Office of the Cloistered Emperor), which was held by a succession of emperors who abdicated to devote themselves to behind-the-scenes governance, or insei.

Who was the first non-Fujiwara emperor since the ninth century?
Output: Go-Sanjō

Input: Cotton
By the 1840s, India was no longer capable of supplying the vast quantities of cotton fibers needed by mechanized British factories, while shipping bulky, low-price cotton from India to Britain was time-consuming and expensive. This, coupled with the emergence of American cotton as a superior type (due to the longer, stronger fibers of the two domesticated native American species, Gossypium hirsutum and Gossypium barbadense), encouraged British traders to purchase cotton from plantations in the United States and plantations in the Caribbean. By the mid-19th century, "King Cotton" had become the backbone of the southern American economy. In the United States, cultivating and harvesting cotton became the leading occupation of slaves.

What was cotton called in the 19th century?
Output:
King Cotton
