1. Create SSH Key
In the user's home directory, see if there is an. SSH directory, and if so, look at this directory there are no Id_rsa and id_rsa.pub these two files, if already have, can jump directly to the next step. If not, create SSH Key:
Enter the home directory. SSH directory (~/), execute the following command:Ssh-keygen-t rsa-c "497049229@qq.com"The first prompt to enter the save file name can not be entered, it will be saved by default as Id_rsa.pu

They rely on the information They extract, the warehouse in order to work more effectively and efficiently. They also ultimately determine whether or not your Data Warehouse project met its stated goals. For these reasons, your project must is bu

Introduction
With the rapid development of China's financial industry, it is an urgent problem for the bank to support the decision analysis by classifying and storing the customer data, analyzing the automatic discriminant of the various factors, and digging out the information needed by the bank managers and the business analyst in the presence of a large amount of data. Data inconsistency, external data, and unstructured data problems are difficult to resolve because the real situation of th
Microsoft's Parallel Data Warehouse (Parallel data Warehouse, abbreviated PDW) was released last year with SQL Server 2008 R2, designed to compete with Oracle Exadata and Teradata. PDW a true sense of the ability to mix workloads, users can extend data from multiple physical servers with a familiar SQL Server database engine.
Parallel Data Warehouse is not a sof

Most warehouse-based data architectures can be summarized as:
Data source-->ods (operational datastore)-->DW-->DM (data mart)

First, data extraction:
It can be understood that data from the source data is pumped into the ODS or DW.

Job description:
this process, such decision-making and special data storage is called Data Warehouse (DW ).
W. H. Inmon defines a data warehouse as a topic-oriented, integrated, stable, and time-varying data set that supports management decision-making.
A topic is a standard for data classification. Each topic corresponds to an objective analysis field, such as a customer or a store. It can help decision-making to integ

1. Introduction
Microsoft SQL Server 2008 provides a comprehensive data warehouse platform. It allows you to build and manage your data warehouse using a separate, integrated suite of products, and allows you to provide insights to your users. It can meet the needs of the largest enterprise and give your end users and it employees the rights they need.
The first thing to focus on deploying in SQL Server 2
solution linear algorithm,The idea is to do the DFS sequence directly to the tree, all the nodes are replaced with the color sequence that is dyed on that node, and then you can find the interval in the DFS sequence of the subtree corresponding to each node (the nodes on the subtree must be contiguous in the DFS sequence).So the problem was completely transforme
Test instructionsN points form a tree. gives the root node p and the tree structure information.Outputs the f[i of each point]. F[i]: The number of numbers in all sub-nodes with a number smaller than I in the root of I.0Ideas:Method One: Direct DFS, enter the node x to record the number of smaller than X. When you come out X, record the number of smaller numbers than X. Subtraction is f[x]. Combines a tree-like array.Method Two: Write down the
non-block (with a common root), and then the place where the block is removed and the surrounding non-block is connected. Until a block in one place is not connected to the boundary, it is no. Otherwise, the last is yes.Locally with DFS explosion, the BFS should be resolved. But directly hand in, the evaluation machine with DFS will not explode stack ...Code:#include #include#include#include#include#includ
Warehouse receiving and receiving functions are available in many systems. May be called differently. Some may be the quantity, and some may be the amount. Here, I take the amount as an example to implement warehouse receiving and warehouse receiving in many ways. One is implemented in languages and the other is implemented using triggers. They have their own mer
A data warehouse (DW) cleans, extracts, and transforms a large amount of traditional database data for transaction processing, and reorganizes the data according to the needs of decision topics. A large number of organizations have discovered that in today's competitive and fast-growing world, data warehouses are a valuable tool.
