Introduction to ETL technology: Introduction to ETL, data warehouse, and etl Data WarehouseETL is the abbreviation of Extract-Transform-Load. It is used to describe the process of extracting, transforming, and loading data from the source to the target. ETL is commonly used in data warehouses, but its objects are not l

As a data warehouse system, ETL is a key link. If it is big, ETL is a data integration solution. If it is small, it is a tool for data dumping. Recall that there have been a lot of data migration and transformation operations over the past few years. However, the work is basically a one-time job or a small amount of data. You can use access, DTS, or compile a small program on your own. However, in the data
ETL scheduling development (1) -- writing instructions, etl Scheduling
Preface:
During database operation and maintenance, files are often transferred between systems to perform operations such as data extraction, conversion, and integration. In addition, statistical scheduling is performed after data integration. Here, I will describe an ETL scheduling developed
ETL scheduling development (5) -- connect to the database to execute database command subroutines and etl Scheduling
In ETL scheduling, you need to connect to the database to read and write data. The following subprograms use the input database connection string and database commands (or SQL) to perform the required operations:

During database management, extraction, conversion, and loading (ETL, extract, transform, and load) are three independent functions that constitute a simple editing task. First, read the data in the specified source database and extract the required sub-dataset. Then, the conversion function uses rules or drop-down lists to process the acquired data or create connections with other data, so that it can be converted to the desired state. Finally, we us
XCL-Charts powerful dashboard, xcl-charts dashboard
The dashboard in XCL-Charts is one of the most troublesome diagrams I encapsulate. The reason is that people who have used it all know that this type of graph is too special. It is not easy to encapsulate it for most cases.
Fortunately, after a hard work, we finally developed a set of methods that we felt okay.
Developer dashboard is a new feature provided since sharepoint2010. It is an information panel located at the bottom of the page, it can directly display the running time of each component on the current page, database calls generated by the running of the current page, each database call, and other information. For SharePoint website development, maintenance and debugging are very helpful.
