key may be helpful when you need to uniquely identify a property. For example, when you define attribute relationships later in this tutorial," City and county " property must uniquely determine" Province / City / Autonomous Region " property. However, in different provinces/Some cities may have duplicate names. To do this, you create a" City and county " property of Stateprovincenameand the Citya key combination of columns. (The purpose of the definition is to make the property unique, and
concepts, such as active users, VIP users and so on. The goal of this level of data model is to express business processes flexibly, to ensure data consistency, uniqueness, correctness, to keep data synchronization with the source data at the least cost, and that the data model of this level is not recommended to be used directly by the business people who do not know the technology, therefore, the use of the relational three-paradigm model is the best choice.The market tier uses the dimension
For details about DOM element dimensions, such as offsetWidth, scrollWidth, and clientWidth, offsetwidth
Example:
1. offsetWidth
OffsetWidth = border + padding + height;Here: 50 + 50 + 200 + 50 + 50 = 400
Note:OffsetWidthYou cannot obtain the correct value in the div of display: none. You can use jquery'sOuterWidth ()Correct
2. clientWidth
ClientWidth = padding + height-Scroll bar The value is 50 + 200 + 50-17 = 283.

"Element Drag to change the size" in fact, and "element drag" a principle, but the dynamic change of the object is different, mainly in the top, left, width, height of the use, relative implementation is also very easy. The following is attached to the source code prototype, to figure out the principle of further expansion of other practical applications, the idea becomes simple, much clearer. First to see the effect: Tahe County Xianqing MachineryBelow is the JavaScript Codeview source print?
In addition to the time dimensions that appear in previous articles, there is a special dimension-parent-child dimension in addition to the design of the snowflake dimension. A parent-child dimension is special in that it contains a reference structure based on a recursive relationship (recursive relationship), and in my article I mentioned how to design and make a SSRS report based on a parent-child hierarchy, but that report is based on the Data war
This article compares the differences between the numpy of MATLAB and Python in terms of dimension indexes:1, the starting point of the index is different: Matlab starting position index is 1,python 02. The parentheses of the index are different: elements in MATLAB can be indexed by parentheses, and Python uses brackets:A (1, 2) in MATLAB represents the first row of a, and the elements of the second columnPython's numpy in A[1, 2] represents the second row of a, the element of the third columnA
Once you have familiarized yourself with the creation of the following three dimensions, you are ready to start creating our first Cube.

SSAS series-about the design of parent-child dimensions
We'll use the following scripts to create some dimension tables and fact tables with the source of AdventureWorksDW201
