Because the database design experience is insufficient, and the knowledge system is imperfect, the database analysis ability is not enough, resulting in the previous version (http://www.cnblogs.com/qiangzai/p/8032833.html) design errors a lot; this time, after my deliberation, The database has been greatly adjusted, hoping to continue to improve and repair in the future learning.The E-r chart is as follows:this project uses MYSQL Create

DescriptionAfter a day trip with his friend Dick, Harry noticed a strange pattern of tiny holes in the door of hisSUV. The local American Tire store sells fiberglass patching material only in square sheets. What is thesmallest patch that Harry needs to fix his door?Assume that the holes are points on the integer lattice in the plane. Your job is to find the area of thesmallest square that will cover all the
Question:
Points are given in the two-dimensional coordinate system, and the area of the smallest square can be covered (the side of a square is not necessarily a parallel coordinate axis)
Solution:
For a point, if the coordinate axis rotates degrees A (in radians), then x' = x * Cos (
Given some vertices, find the smallest square to cover all vertices.
Idea: rotate a square with a rotation angle (0 ~ 90), using the three-way method, find the smallest square (correctness is not proved ).
# Include
The coordinates of many points are given and covered with the smallest square.
Question: three points. Pay attention to precision ····. Draw a diagram of the formula Shenma to solve the problem.
Double mid1 = (left + right)/2;
Double mid2 = (mid1 + right)/2;
Compared
Double mid1 = left + (right-left)/3;Double mid2 = right-(right-left)/3;Higher accuracy is required.

security information doesn't mean just collecting security logs, you need to know where your sensitive data is and what the data is. In April of this year, the Texas State Audit Office had a data leak, about 3.5 million people's names, social Security numbers and mailing addresses, as well as a number of people whose birth dates and driving licence numbers were
It is not difficult for Java to access HDFs through the APIs provided by Hadoop, but the computation of the files on it is cumbersome. such as grouping, filtering, sorting and other calculations, using Java to achieve are more complex. The Esproc is a good way to help Java solve computing problems, but also encapsulates the access of HDFs, with the help of Esproc to enhance the computing power of HDFS files, structured semi-structured data can be easi

efficient than Intel core chips and are more suitable for applications in high-performance computing systems. When using multi-core running software, ARM chips with the same clock frequency have the same efficiency as x86 chips. When the performance is the highest, the x86 chip runs more efficiently. When running software on a single core, the performance of exynos5250 is over 1.7 times that of tegra3.
