The SSAS Date dimension is basically present in all Cube design processes, and it is difficult to see an OLAP database with no time dimension. However, depending on the project requirements, the Date dimension may be designed differently, so there are a few issues to be aware of when designing the Time dimension: What

Original: SSAS Series--"02" Multidimensional Data (Dimension object)1. What is dimension? In mathematics, it is called a parameter, which is the number of independent space-time coordinates in physics. 0-Dimensional is a point, 1-dimensional is a line, 2-dimensional is a long and wide (or curved) area, 3-dimensional is 2-dimensional plus the height to form the volume surface. In physics, Time is the fourth

Merge data 3 ----------- conditional split and slowly changing Dimension components Search for Excel and databases using productnumber. When the data is in Excel but not in the database, it is added; when all data is in Excel, it is updated; if there is data in the database but there is no data in Excel, It is deleted.Delete the database if it is no longer in the database. I. Conditional split componentIf you use the product table for testing, there

Returns an array dimension (number of layers) call. $arr = array(array(1,2=>array(1,2,3)),2=>array(1=>array(array(array())),2),3);echo GetArrLv($arr); For example, if implode is a multi-dimensional array, an error is returned. of course, we can use an array similar to array_search (true, array_map ('is _ array', $ arr )) this method is used to determine whether it is 2-dimension + (for example, please Hold

I am currently a very important part of the work is to participate in or responsible for a number of clusters in the Department of Maintenance, application development and optimization, including: HBase cluster, Storm cluster, Hadoop cluster, Super Mario cluster (real-time streaming system developed within the department), etc., with the expansion of business, The number of cluster machines has been small and large. Next is me to myself this 1 years, in the cluster application and the operation

Instance description 1:Slowly changing dimensions. For example, if you register a csdn account with the address, phone number, and other information you fill in, your address will change, but it will change once in a long time. This is a Slow Changing Dimension. See type1, type2, and type3.Type1-full coverage, keep the latest data (keep most recent values in target)Type2-full history (keep a full history of changes in the target)Type3-keep the latest

if you are using WVGA as a benchmark, Put it on the HVGA and it will not be fully displayed. The problem will be more pronounced on the QHD. Even the same hdpi WVGA and qHD have problems, and QHD can show more than WVGA.use dimension resources to solve problemsAs can be seen from the above questions, the density-independent units can not solve the above problems. Of course, there is a choice for each resolution to make a layout, but this will cause a

Use the java date class to generate a data warehouse dimension table Use the java date class to generate a data warehouse dimension table Date class: Returns the number of milliseconds of a relative date. Accurate to milliseconds, but does not support date internationalization and Time Zone display. The Date class evolved from the Java Development Kit (JDK) 1.0. At that time, it only contained several metho

Further to this, improvements have been made to the dimension of the time frame in which the customer allows the service, and the C # version has been translated into Java, reinforcing the more graphical presentation path (which continues to be plotted in Python's matplotlib).The time-range dimension here refers to each customer having their own service time, such as from 10:00 to 12:00, which allows the hu

Generating a Data Warehouse dimension table using the Java date classDate class:The most basic date-time class that returns the number of milliseconds for a relative date. Accurate to milliseconds, but does not support the internationalization and sub-timezone display of dates. The date class began to evolve from the Java Development Package (JDK) 1.0, when it contained only a few methods of acquiring or setting up parts of a date data, such as month,

I have long wanted to summarize some of the Internet products that we see in the time dimension. With the continuous postponement of this log. The more I find out more about the design of similar web products. This is a good thing. I think it's time to make a summary list.

In the article "using calculated members to achieve the daily average", we achieved the average of the balance by establishing a calculation member, so as to guarantee the dimension of the bus structure! The disadvantage of this method, of course, is that many computational members need to be set up, and the efficiency of the calculated members is poor. In this section, we use the custom rollup method of the dimen
