Problem: Database:

Having produced a conceptual data model that users are happy with, the next stage is to translate this into a schema that implements the relevant data structures within the database. This process is often called logical database design, and the output is a logical data model expressed in the form of a schema. Whereas the conceptual data model is (in theory at least) independent of the choice of database technology, the logical data model will be expressed in terms of a particular database model supported by the chosen DBMS. (The terms data model and database model are often used interchangeably, but in this article we use data model for the design of a specific database, and database model for the modelling notation used to express that design.)

What form is the input of a logical database design?

A: unanswerable

Problem: A second New Haven gastronomical claim to fame is Louis' Lunch, which is located in a small brick building on Crown Street and has been serving fast food since 1895. Though fiercely debated, the restaurant's founder Louis Lassen is credited by the Library of Congress with inventing the hamburger and steak sandwich. Louis' Lunch broils hamburgers, steak sandwiches and hot dogs vertically in original antique 1898 cast iron stoves using gridirons, patented by local resident Luigi Pieragostini in 1939, that hold the meat in place while it cooks.
Who is the founder of Louis' Lunch in New Haven?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The word "paper" is etymologically derived from Latin papyrus, which comes from the Greek (papuros), the word for the Cyperus papyrus plant. Papyrus is a thick, paper-like material produced from the pith of the Cyperus papyrus plant, which was used in ancient Egypt and other Mediterranean cultures for writing before the introduction of paper into the Middle East and Europe. Although the word paper is etymologically derived from papyrus, the two are produced very differently and the development of the first is distinct from the development of the second. Papyrus is a lamination of natural plant fibres, while paper is manufactured from fibres whose properties have been changed by maceration.
What plant was used in Egypt to make papyrus?
A: Cyperus

Question: The establishment of Ottoman military aviation dates back to between June 1909 and July 1911. The Ottoman Empire started preparing its first pilots and planes, and with the founding of the Aviation School (Tayyare Mektebi) in Yesilkoy on 3 July 1912, the Empire began to tutor its own flight officers. The founding of the Aviation School quickened advancement in the military aviation program, increased the number of enlisted persons within it, and gave the new pilots an active role in the Ottoman Army and Navy. In May 1913 the world's first specialized Reconnaissance Training Program was started by the Aviation School and the first separate reconnaissance division was established.[citation needed] In June 1914 a new military academy, the Naval Aviation School (Bahriye Tayyare Mektebi) was founded. With the outbreak of World War I, the modernization process stopped abruptly. The Ottoman aviation squadrons fought on many fronts during World War I, from Galicia in the west to the Caucasus in the east and Yemen in the south.
Is there an answer to this question: What was the first date that the Ottoman empire had an air-based military unit?

Answer: June 1909

QUES: In the 1772 First Partition of Poland, the Prussian king Frederick the Great annexed neighboring Royal Prussia, i.e. the Polish voivodeships of Pomerania (Gdansk Pomerania or Pomerelia), Malbork, Chemno and the Prince-Bishopric of Warmia, thereby bridging the "Polish Corridor" between his Prussian and Farther Pomeranian lands and cutting remaining Poland off the Baltic Coast.

The former Polish Pomerelian lands beyond the Vistula River together with Malbork and Chemno Land formed the Province of West Prussia with its capital at Marienwerder (Kwidzyn). The Polish Partition Sejm ratified the cession on 30 September 1773, whereafter Frederick officially went on to call himself a King "of" Prussia.
