a collection of entities and relationship amongst the entities. b) What is the data hierarchy? Briefly explain this in your own words. Data hierarchy is representation of data in pyramid format with smallest form of data on th top of pyramid and biggest form at the bottom of it. Smallest form of data bit and after that characters. Collection of fields forms a records and multiple records forms a file. And multiple files together forms a database which is at bottom of hierarchy as it is bigger

Among these three time-series models‚ the decomposition with exponential smoothing trend has the smallest MAPE and RMSE for both historical period and holdout period. Therefore‚ we use this model and the data from January 2001 to October 2011 to perform the ex-ante point and interval forecasts

The Facebook Sonnet” clearly shows that the smallest thing can become the biggest part of life. The first stanza introduces you to Sherman Alexie’s description of Facebook in “The Facebook Sonnet.” It talks about reuniting with old high school friends and how it keeps you connected to them for as long you all shall live in the "endless high-school/Reunion" (lines 1-2). The middle of the first stanza says‚ "Welcome to past friends / And lovers‚ however kind or cruel" (lines 2-3)‚ this shows that

This was measured with a ruler where the smallest unit shown was 0.1 cm. Half of this number (0.05 cm) is the uncertainty‚ but because there was uncertainty at either end of the measurement‚ this must be doubled. Therefore the uncertainty in length was 0.1 cm.

Music is a great place to show creativity and be yourself‚ right? But what happens whenever an artist pours all of his creativity into a song‚ and he puts it up for sale. Potential sales‚ in a perfect market‚ would be pretty high. But introduce file-sharing‚ and the sales are cut by about one third of the original amount. File-sharing is an activity in which one user downloads something from another user’s files. Online piracy stems from this‚ as one person downloads something‚ either legitimately

and the lowest was n = 3. The colors with the highest frequencies and lowest wavelengths had the largest emission of energy to fall through the most energy levels. Similarly‚ the largest wavelengths and the smallest frequencies from colors had the smallest emission of energy and the smallest fall in energy level. The falling of energy levels is indicative and a negative value for ΔE‚ which supports the

causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the solution in a period of 10 minutes. Also‚ as the size of the cube increased‚ the surface area increased more quickly than the volume such as the difference between the volume of the biggest (3cm) cube and the smallest cube (0.5cm) was only 26.9 ㎤
