Q: While there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department. Thus different departments need different views of the company's database.

A: How many conceptual or physical views of data are there?

Q: The inhabitants of the British Isles have been drinking ale since the Bronze Age, but it was with the arrival of the Roman Empire in its shores in the 1st Century, and the construction of the Roman road networks that the first inns, called tabernae, in which travellers could obtain refreshment began to appear. After the departure of Roman authority in the 5th Century and the fall of the Romano-British kingdoms, the Anglo-Saxons established alehouses that grew out of domestic dwellings, the Anglo-Saxon alewife would put a green bush up on a pole to let people know her brew was ready. These alehouses quickly evolved into meeting houses for the folk to socially congregate, gossip and arrange mutual help within their communities. Herein lies the origin of the modern public house, or "Pub" as it is colloquially called in England. They rapidly spread across the Kingdom, becoming so commonplace that in 965 King Edgar decreed that there should be no more than one alehouse per village.

A: When did the inhabitants of the British Isles begin drinking ale?

Q: To relieve pressure from the expected German attack into Alsace-Lorraine, Napoleon III and the French high command planned a seaborne invasion of northern Germany as soon as war began. The French expected the invasion to divert German troops and to encourage Denmark to join in the war, with its 50,000-strong army and the Royal Danish Navy. It was discovered that Prussia had recently built defences around the big North German ports, including coastal artillery batteries with Krupp heavy artillery, which with a range of 4,000 yards (3,700 m), had double the range of French naval guns. The French Navy lacked the heavy guns to engage the coastal defences and the topography of the Prussian coast made a seaborne invasion of northern Germany impossible.

A:
What did Napoleon III plan to relieve pressure from an expected German attack?
