As early as the end of 1990s, business intelligence technology was selected by a computer magazine as one of the most influential IT technologies in the next few years. Although the entire IT industry has been sluggish in recent years, product R D and applications related to business intelligence are in the ascendant, and hundreds of IT enterprises are constantly entering this emerging field, bi applications have even become another new "highlight" in the IT field ". What is business intelligen

the risk of the application. Figure 7 is a decision tree established to solve this problem. We can see the basic components of the decision tree: decision nodes, branches, and leaves. 3. Genetic Algorithms Based on evolutionary theory, and using genetic integration, genetic variation, and natural selection and other design methods of optimization technology. 4. Nearest Neighbor Algorithm How to classify each record in a dataset. 5. Rule Derivation In a statistical sense,

The following improvements and new features make it easier and quicker for users to use PivotTable and online analytical Processing (OLAP) PivotTables in Microsoft Excel2010. Computing performance In Excel2010, multithreading helps to speed up the calculation in the PivotTable report, thereby improving the overall performance of the PivotTable report. This means that you can get results faster when you work with large amounts of data, such as sortin

Let's talk about bi, put an end to the "fake", "big", and "empty" words, and redescribe Bi in terms of definition, basic technology, terminology, instance application, and expansion, consolidate your understanding of Bi. I. DEFINITION OF Bi Bi is the abbreviation of business intelligence. It is a collection of technologies that help enterprises make better use of data to improve decision quality, it is a process of drilling information and knowledge from a large amount of data. Simply put, i

Or, when you use DDL when the database is busy, there will also be two waiting events.Iv. database cache ViewThere is a view that shows the information of the objects cached in the database cache, Which is V $ db_object_cache.OWNER: object OWNERNAME: Object NAMEDB_LINK: Database Link nameNAMESPACE: NAMESPACE.

The purpose of data collection is to make correct decisions based on the database content. The deep hiding of these massive data is a lot of business patterns (pattern), Rules (rules), and these hidden "business knowledge" is of great significance to the current data owners, therefore, they may pr

Chapter 4 Section 3Pivot Table component terminology One of the purposes of designing the pivot table component is to make the table column data source and the multi-dimensional data source user interface consistent with the programming model. Although each type of data source has special requirements, we want the two data sources to be identical in appearance and usage. At the same time, we consider that for business people who only need to extract the necessary data so that they can complete t

Many friends who are engaged in Bi projects are concerned about how to display multi-dimensional data sets. I recommend using OLAP components under Dundas. This article mainly describes the use of Dundas OLAP controls, issues that

In fact, the technical point is that business intelligence is composed of data warehouses, data queries and reports, data mining, Online Analytical OLAP, budgeting and forecasting, and other parts, data is mined through modeling and presented to decision makers in an intuitive manner. To put it bluntly, we will review the past from the perspective of today, look forward to the future, and turn past in

not a bi report tool, because Excel does not have the ability to connect to the data source. At best, it is a spread sheet. However, the powerful format function of Excel allows the report maker to fold. Even later, almost all bi vendors provided plug-ins for Microsoft Excel, excel can be connected to the Bi data source, changing to a bi report tool, and the ugly duckling becomes a swan. 5) Bi advanced application mode overview-Online Analytical Processing,

Data ZT: A brief explanation of common nouns in data Warehouse Data Warehouse in the middle of the 80 's, Mr. William H.inmon, the "Father of the warehouse", defined the concept of data warehousing in his book "Building Data Warehouses," and then gave a more precise definition: Data warehousing is a topic-oriented, integrated, A data collection that is related to time and cannot be modified. Unlike other database applications, a data warehouse is more like a process for the integration, proces
