stud jewelry for earrings wholesale amazon ETL is an abbreviation of English Extract-Transform-Load, which is used to describe the process of the data from the source of the data, transform, loading (load) to the destination end. The term ETL is more commonly used in data warehouses, but its objects are not limited to data warehouses. The data warehouse is a strategic collection of all types of data support for all types of data support for all levels of decision -making. It is a single data storage, which is created for the purpose of analytical reports and decision -making support. For enterprises that need business intelligence, provide guiding business processes improvement, monitoring time, cost, quality and control. etl is the process of loading the data of the business system after being extracted, cleaning and conversion to the data warehouse. The purpose is to integrate the scattered, zero -chaos, and poor standards in the enterprise to provide an analysis basis for the company's decision -making. ETL is an important part of the BI (commercial intelligence) project. The expansion information: etl and elt:
etl described, common methods include ETL or ELT (Extract-load-transform) and mixed use. Generally, the more a large amount of data, complex conversion logic, and the purpose of the destination is a database with strong computing power. The process of etl (oreLT) can be developed in any programming language. Because ETL is an extremely complicated process, the handwriting program is not easy to manage. More and more companies use tools to assist ETL development and use it to use it The built -in MetAdata function to store the correspondence and purpose of the source and purpose (MAPPING) and conversion rules. The tools can provide a strong connection function () to connect the source and destination end. Developers do not need to familiarize the structure of various different platforms and data, and can also develop. Of course, for these benefits, the price paid is money.

It is a necessary step after the front start. Compared to the relationship database, the data warehouse technology does not have a strict mathematical theoretical basis, and it is more oriented to actual engineering applications. Therefore, from the perspective of engineering applications, load data according to the requirements of the physical data model and processes the data. The processing process is directly related to the experience. At the same time, the work of this part is directly related to The quality of the results of online analysis and data mining. The data warehouse is an independent data environment. The data storage medium of data storage medium of the data processing environment, external data source and offline needs to be introduced into the data warehouse by drawing the process. , Conversion, incremental, scheduling, and monitoring; the data in the data warehouse system does not require the data to synchronize with the data in the data processing system in real time, so ETL can be carried out regularly. However, the operation time, sequence, and success or failure of multiple ETLs are critical to the effectiveness of the information in the data warehouse. more specifically you can view Baidu Encyclopedia
