data Independence is based on the separation of logical structure and physical structure of data, the user operates data with simple logical structure without considering the physical structure of data, and the transformation work is realized by database management system. Data independence is divided into the physical independence of data and the logical

I think everyone has read my previous question. is The Spit Groove entrepreneurship is very difficult. My ability is not enough, basically my experience is segmentfault above one of the questions obtained. Here, I would like to thank those who have helped me, no matter how naïve the question will be enthusiastic to answer you. Of course, I have a new problem. is the Mo Mo's eight picture, Mo

of the element. DemoTo explain how all this works together, it is necessary to create and test a sample application. For example, a design of a picture with a density of xhdpi or 320dpi,200x200 px is used. For simplicity, name the picture resource "Android_logo". With the density at 320dpi,200x200 PX Image resolution as the desired physical size, the replaceable image size can be computed.Density of xhdpi (320dpi),200x200px PicturesAfter calculating the image size required for a specific densit

Recent brush algorithm problem encountered a problem:Give a sequence of length n {a[1], a[2], a[3], ..., A[n]}, and M-group inquiry (L[i], r[i], k[i]).The number of occurrences of the sequence subscript interval in [L[i], R[i]] coprime (Greatest common divisor 1) is in this interval. Input Description:The first line, two positive integers n, m (1≤n, m≤50000). The second line, n positive integers a[i] (1≤a[i]≤n) describes the sequence. Next m line, three positive integers per line l[i], R[i], K[i

The book "dark time" was written by Liu weipeng. Mr. Liu weipeng is also a very powerful figure in the computer field and works for the Microsoft Asia Research Institute. The essence of this book is actually very similar to Mr. Li xiaolai's book "Treat time as a friend", which is based on the efficient use of time. In fact, when you look at it later, I believe many people will not be interested. I even suspect that Mr. Liu is a computer scientist? Or research psychology? Or research translation?

MO Team Algorithm Summary preface:Again, like the Chairman tree, Oi god Ben invented the algorithm.When I first heard the name of the algorithm, I guessed that the team was a great god Ben. Did not expect to know that he unexpectedly is our seniors!

the pixel density.　#81 WPF UnitsIn Windows Form, the control size is controlled by pixel. In WPF, device-independent, which is controlled by WPF units.1 WPF unit = 1/96 inch. That is, on a 96DPI display, 1 WPF Unit = 1 pixel.That is, in a 120DPI environment, 1 WPF unit = 1.25 pixels. (120/96).Similar device independence can be achieved in Windows Form by modifying the AutoScaleMode property of the form, which is automatic in WPF.Formula: # pixels = (
