In OLAP technical documents, there are two main types that are often mentioned: multidimen1_olap (molap) and Relational OLAP (ROLAP). In order to combine the advantages, based on the two, a new type of Hybrid OLAP (holap) is proposed, that is, Hybrid OLAP technology. From a technical point of view, ROLAP (microstrategy implementation) and molap (COGNOS implementation) have their own advantages. The former is based on relational databases. Its OLAP eng

Question: If all the characters of string 1 appear in the second string in the order of the strings, then string 1 is called a substring of string 2. Note that the character of a substring (string 1) must appear in string 2 consecutively. Compile a function, enter two strings, calculate their longest public substrings, and print the longest public substrings.
For example, if two strings BDCABA and ABCBDAB are input, and both BCBA and BDAB are their longest common substrings, the output length is

topic: If all characters in a string are in the order in which they appear in the string, then a string called a substring of string two. Note that characters that do not require substring (string one) must appear consecutively in string two. Write a function, enter two strings, ask for their longest common subsequence, and print out the longest common subsequence.For example: Enter two strings Bdcaba and Abcbdab, string BCBA and Bdab are their longest common subsequence, then output their lengt

tools
The previous tools are based on a prior model and have been used to detect known patterns and rules. Automatic Processing of complex, heterogeneous, and large-scale data often fails, therefore, we need to visualize the data analysis process to better explore patterns and find problems. Currently, the best data analysis visualization tools on the market are tableau and ggplot2 in R. These products have the following advantages:

There are many visual tools, such as tableau, a variety of JS framework, I personally feel it should be the best to learn JS, because JS does not need the environment, every computer has a browser, and like matplotlib need a development environment such as python, or more troublesome, But after all, using Python to process the data, this article is to write some of their own study notes, of course, know what the most important painting (I do not know-

When "web Analytics" develops into "data intelligence", there is no doubt that data analysts should also have some changes in their work, in the past, primarily web-centric and channel-specific tactics, while in the future they need to be responsible for more strategic, business-oriented and (large) data expertise.The primary focus of data analysts should not be on lower-level infrastructure and tool development. The following points are the opportunity areas for data analysis:1. Processing: Mas

There were two major voices for big data technology at the o'reilly Media Conference in New York in September this year: enterprise level and agility. We know that enterprise-level business intelligence products include Oracle Hyperion, SAP businessobjects, and IBM cogonos, while agile products include qlikview, tableau, and tibco spotfire.
If it turns out that big data must purchase enterprise-level products, it means that big data will spend a lot
