Question: The conceptual view provides a level of indirection between internal and external. On one hand it provides a common view of the database, independent of different external view structures, and on the other hand it abstracts away details of how the data are stored or managed (internal level). In principle every level, and even every external view, can be presented by a different data model. In practice usually a given DBMS uses the same data model for both the external and the conceptual levels (e.g., relational model). The internal level, which is hidden inside the DBMS and depends on its implementation, requires a different level of detail and uses its own types of data structure types.
Is there an answer to this question: How does the conceptual view handle how data is managed?

Answer: abstracts away details


Question: One boarding house, College, is reserved for seventy King's Scholars, who attend Eton on scholarships provided by the original foundation and awarded by examination each year; King's Scholars pay up to 90% of full fees, depending on their means. Of the other pupils, up to a third receive some kind of bursary or scholarship. The name "King's Scholars" is because the school was founded by King Henry VI in 1440. The original School consisted of the seventy Scholars (together with some Commensals) and the Scholars were educated and boarded at the foundation's expense.
Is there an answer to this question: In what year did King Henry VI's reign begin?

Answer: unanswerable


Question: Niels Bohr introduced the first quantized model of the atom in 1913, in an attempt to overcome a major shortcoming of Rutherford's classical model. In classical electrodynamics, a charge moving in a circle should radiate electromagnetic radiation. If that charge were to be an electron orbiting a nucleus, the radiation would cause it to lose energy and spiral down into the nucleus. Bohr solved this paradox with explicit reference to Planck's work: an electron in a Bohr atom could only have certain defined energies En
Is there an answer to this question: What statement did Bohr make about the electron of an atom, citing Planck's work?

Answer: an electron in a Bohr atom could only have certain defined energies


Question: Ethnic Russians constitute 25.5% of the country's current population and 58.6% of the native Estonian population is also able to speak Russian. In all, 67.8% of Estonia's population can speak Russian. Command of Russian language, however, is rapidly decreasing among younger Estonians (primarily being replaced by the command of English). For example, if 53% of ethnic Estonians between 15 and 19 claim to speak some Russian, then among the 10- to 14-year-old group, command of Russian has fallen to 19% (which is about one-third the percentage of those who claim to have command of English in the same age group).
Is there an answer to this question: How much of the native Estonian population speaks English?

Answer:
unanswerable
