ETL is responsible for the distribution, heterogeneous data sources such as relational data, flat data files, such as the extraction of the temporary middle tier after the cleaning, transformation, integration, and finally loaded into the data warehouse or data mart, to become the basis of online analytical processing, data mining. If the frequency of data conversion or not high requirements can be manually implemented

Customer Perspective: Oracle ETL Tool ODIData integration has become the enterprise in the pursuit of market share of the key technology components, and rely on manual coding in different ways, more and more enterprises choose a complete data integration solution to support its IT strategy, from big data analysis to cloud platform integration.A recent study by Dao Research compares the differences between several of the world's leading data integratio

See you share a lot of Hadoop related content, I introduce you to an ETL tool--kettle.Kettle is an ETL tool of Pentaho company Open source, like Hadoop, is also Java implementation, the purpose is to do data integration when the data extraction (Extract), conversion (Transformat), load (loading) work. There are two script files in Kettle, transformation and job,transformation complete the fundamental transf

Different map service platforms have diverse requirements on map file formats, and files used by ArcGIS are difficult to be used on other platforms, therefore, a format conversion service is required to overcome the trouble of using different platforms. The following uses the conversion from TIFF format to geotiff format as an example.First, you need to prepare several items:1. Make sure that ArcGIS data interoperability for desktop is installed.2. Check data interoperability in the extended mod

This section describes how ETL (data extraction, loading, and conversion) of my game transaction data analysis project is implemented.Let's talk about the source system first. Because the server of our transaction master station is not hosted in the company, we cannot directly extract data from the source system. As a matter of fact, we already have a simple data analysis system. We don't have to worry about this. We did not use the sqlserver2005 Bi p

During ETL usage. Incremental extraction is more widely used than full extraction. How to capture changed data is the key to incremental extraction. There are generally two requirements for the capture method: accuracy, which can

Lesson 1st: create a simple ETL package, create a package for extracting data from a single flat file source, and then convert the data using the search conversion function, finally, load the data to the factcurrency fact data table of the adventureworksdw sample database. However, a single flat file is rarely used in the extract, transform, and load (ETL) process. A typical

ETLIs the abbreviation of extract-transform-load. It is used to describe the process from the source end to extract (extract), transpose (Transform), load (load) to the target end.ETLThe term is commonly used in data warehouses, but its objects are not limited to data warehouses.

It extracts data efficiently and stably (data migration tool ). Kettle has two types of script files: transformation and job. transformation completes basic data conversion, and job controls the entire workflow.2.

When you log on using the resource pool (repository), the default username and password is admin/admin. B. When a job is stored in a resource pool (a common repository uses a database), the following command line is used when you use Kitchen.bat to perform a job:Kitchen.bat/rep kettle/user admin

Microsoft integration services is a platform that can generate high-performance data integration solutions, including extracting, transforming, and loading (ETL) packages for data warehouses. Integration Services includes graphical tools and wizard used to generate and adjust packages; tasks used to execute workflow functions (such as FTP operations), execute SQL statements, and send emails; the data sources and targets used to extract and load data.

For everything, supervision is an effective way to improve itself, as is BI. In my personal experience, BI supervision can be divided into two types (Welcome to the discussion ):Runtime supervision(Runtime Monitoring)AndMonitoring of data warehouse health status(DW Healthy Monitoring):1. Runtime supervisionThe so-called runtime supervision refers to the process of monitoring data from the data source to the data warehouse. In general, it is to supervise the
