Rollup and cube, oralcerollup of Oralce advanced SQLIn oracle SQL query, oracle provides some advanced functions to simplify SQL query statements and improve query performance. The following describes the usage and difference of rollup and cube.1. rollup
Rollup can calculate the subtotal and total of multiple layers of the specified grouping field in the select statement. rollup is very easy to use and effi

In the following, the cube optimization idea is introduced by analyzing the Kylin building cube process.
Create Hive Intermediate Table
Kylin will build a hive's intermediate table in the first step of the cube build, which is associated with all the fact tables and dimension tables, which is a wide table.
Optimization points:
1. Hive table partition op
Comments: In today's course, I will show you how to use css3 to create a 3d cube. the operation method is: top, bottom, left, right, and so on, to achieve the inverted rotation effect of the cube, stunned and worth your reference

About with cube, with rollup and grouping
View the help document of SQL 2005 to find the specific difference between CUBE and ROLLUP.:
The result set generated by CUBE displays the aggregation of all the combinations of the values in the selected column. The result set generated by ROLLUP displays the aggregation of a certain hierarchy of values in the selected c
Clustering function: GROUPING operator used to summarize data: ROLLUP1. the result set generated by the CUBE operator is a multi-dimensional dataset. A multi-dimensional dataset is an extension of fact data. Fact data is the data that records individual events. The extension is created on the columns that the user intends to analyze. These columns are called dimensions. A multi-dimensional dataset is a result set with a package

Mainly through a 3D cube effect example to in-depth understanding of the CSS3 transform properties, the following is a screenshot of the example, coupled with animation can also rotate Yo, is it cool? Put on a picture of the girl you like, you can be bold sister, haha!
First knowledge of transform
As the name suggests: transform. Can think of it can do a lot of things, this attribute has a lot of values, here simply enumerate:

A little special. The bottom left corner of each cube is (0, 0, 0)
Therefore, it is much easier to calculate the area.
Build the X coordinate using a line segment tree
Rm [RT]: the rightmost y value of the interval.
MX [RT]: The maximum y value between jurisdictions
Sum [RT]: total area between jurisdictions
Cover [RT]: whether it is completely overwritten by a certain y value
It is hard to find the size from bottom up.
This is because

WebGL uses FBO to complete the cube Paster effect (with demo source code download), webglfbo
This article describes how WebGL uses FBO to implement the Cube Texture effect. We will share this with you for your reference. The details are as follows:
This article mainly records some basic points of WebGL, and also learns how to use FBO and environment textures. Take a look (WebGL, Chrome, Firefox, and IE11 ar
Basic command: group by cube (Field List );
The CUBE command generates different permutation and Combination Based on the field list, and generates statistical summary based on each combination result.
For example: group by cube (city, job, age); shows the result of the permutation and combination:
1) city, job, age
2) city, job
3) city
4) job, age
5) age

This article mainly introduces how WebGL uses FBO to implement cube Paster effect, and analyzes the specific steps and related techniques of WebGL to implement cube Paster effect in the form of a complete example, the demo source code is provided for readers to download and reference. If you need it, you can refer to the following example to describe how WebGL uses FBO to complete the
The structure of the cube in SSAS
When building the cube and writing MDX in SSAS (SQL Server Analysis Services), it is easy to get confused by some nouns, such as Dimension (dimensions), Measures Dimension (metric dimensions), Measure (Metric), hierarchy (hierarchy), Attribute hierarchy (property hierarchy), Level (rank), cell (unit), member (members), member properties (Members property), Set (set), Turp
