Answer: Physical location

Explanation:

If we place records from, different tables in adjacent physical location, it would increases efficiency of a databases as, database consolidates records from previously store in separate files into a common file. Databases are fast and efficient when they are dealing with large data. When all the information is stored in multiple physical location it is also known as distributed database, as physical location helps to provide the physical and logical path and also protect from default locations in the database.

Consider the clipping of a line segment in two dimensions against a rectangular clipping window. Show that you require only the

Semmy [17]

Answer / Explanation:

Assuming we define the end points as ( x₁ , y₁) and (x₂ , y₂) and the rectangular window edge as ( Xmin ,Ymin and Xmax , Ymax)

The illustration of the above assumption is represented in the diagram below.

Now, suppose the line segment is between the points P₁ = ( x₁ , y₁) , and

P₂ = (x₂ , y₂).

We can then create a line recalling and using parametric form,

P(t) = ( 1 - t) P₁ + tP₂ , t ∈ {0 , 1 },

So, for the X axis, we have,

tₓ = P₁ₓ - x ÷ P₁ₓ - P₂ₓ

We need to note that at this point we need to know the minimum and maximum unclipped values for parameter t from each dimension.

Therefore,

- ( tmin , tmax ) = ( 0,1) means unclipped line

-tmin > tmax means completely clipped out line

– Some other range means partially clipped out line.
