(Dimension): It is a certain angle that people observe data, it is a kind of attribute when consider a problem, attribute set constitutes a dimension (Time dimension, Geography dimension, etc.).
Dimension level: People observe a particular angle of data (that is, a dimension) can also have different levels of detail of various descriptions (Time dimension: date, month, quarter, year).
Member of Dimension: A value of a dimension that is a description of the position of a data item in a dimensi
According to the O ' Reilly 2016 Data Science Payroll survey, SQL is the most widely used language in the field of data science. Most projects require some SQL operations, and even some require only SQL. This article will take you to learn about these mainstream open source SQL engines! Background introductionThis article covers 6 open source leaders: Hive, Impala, Spark SQL, Drill, Hawq, and presto, plus calcite, Kylin, Phoenix, Tajo, and Trafodion.

complex. By defining several important attributes of an entity as multiple dimensions (dimension), the user can compare the data on different dimensions. Therefore, OLAP can also be said to be a collection of multidimensional data analysis tools.
Basic Multidimensional Analysis operations for OLAP include drillthrough (roll up and drill down), slices (slice) and dice (dice), and rotation (pivot), drill ac
user's multi-angle thinking mode, in advance for the user to build multidimensional data model. Here, the dimension refers to the user's angle of analysis. For example, the analysis of sales data, the time period is a dimension, product categories, distribution channels, geographical distribution, customer groups are also a dimension of the class. Once the multidimensional data model is completed, the user can get the data from each analysis angle quickly, and can dynamically switch between eac

A useful function is to display charts. however, if you do not pay attention to it, the summary data will be introduced in the chart, which is the highlighted part. at this time, we actually want to use the information at the same level as the chart. However, when you view the generated chart, you will find that the summary part is imported into the chart, this chart is easy to misunderstand (Red always takes half of it ).
Solution: Click the highlighted

To achieve a high click rate and lower the unit price, drill-up materials must be seamlessly integrated with text files and artists and be optimized based on data analysis. I would like to share with you the experience of doing drill-up exhibitions in our stores, hoping to get some help from new users.

OLAP (Online analytical Processing) is an online data access and analysis for a specific problem. Provides fast, stable, and interactive access to information (multidimensional data) in a variety of possible forms, and allows management decision makers to drill down into the data. first, what is OLAPOLAP (Online analytical Processing) is a kind of software technology that enables analysts, managers, or executives to gain a deeper understanding of data

This feature is used to test the problems of the drilling layer. For example, whether the distance between the hole and the hole is reasonable and whether there are two holes of the same size or different sizes in the same position.

OLAP is designed to meet decision-making support or specific query and report requirements in multi-dimensional environments. Its core technology is the concept of "dimension. "Dimension" is a high-level classification from the perspective of observing the objective world. Dimensions generally contain hierarchical relationships, which are sometimes quite complex. By defining multiple important a

After a user passes authentication, the membership system provides an object that contains information about the current user. For example, you can obtain the attributes of a user object to determine the user name, email address, and last logon time.
An important aspect of the membership system is that you can obtain or set user information without explicitly executing any low-level database functions. For example, you can create a new user by calling the createuser method. The mem
