Extract, transform, load - Wikipedia, the free encyclopedia The transform phase applies a series of rules or functions to the extracted data to derive the data to be loaded. ETL tools have started to migrate into Enterprise Application Integration, or even Enterprise Service Bus, systems that now cover much more than just the extraction, transformation and loading of data. A good ETL tool must be able to communicate with the many different relational databases and read the various file formats used throughout an organization. en.wikipedia.org /wiki/Extract,_transform,_load   (919 words)

What is ETL? - A Word Definition From the Webopedia Computer Dictionary Short for extract, transform, load, three database functions that are combined into one tool to pull data out of one database and place it into another database. Transform -- the process of converting the extracted data from its previous form into the form it needs to be in so that it can be placed into another database. Transformation occurs by using rules or lookup tables or by combining the data with other data. www.webopedia.com /TERM/E/ETL.html   (169 words)

ETL - Extract, Transform and Load Extract Transform and Load – a set of database utilities used to extract information from one database, transform it and load it into a second database. Acronym for database operations of Extract, Transfer, and Load, representing processing overhead required to copy data from an external DBMS or file. ETL has facilities for testing air filters and room recirculators using different standard performance and safety test methods. www.auditmypc.com /acronym/ETL.asp   (247 words)

Teradata Magazine Enterprise View: Tomorrow's real-time ETL imperative Extract and load routines have to bring the data in as is, and then, depending on the business's needs, do the transformation either on the way into the data mart or warehouse (for OLAP and strategic analysis) or on a transaction-by-transaction basis inside of a data-mining algorithm. While transformation mid-stream will never go away entirely, there is a growing need to tie transformation to in-database data mining, in-database data quality, in-database ranking and scoring, in-database integration, in-database parallelism, and in-database scalability, fault tolerance and fail-over. For example, transformation elements such as data mining and data cleansing will be introduced downstream instead of upstream. www.teradata.com /t/page/127085   (1852 words)

iWay DataMigrator - Extract, Transform, and Load ( ETL ) Transform data from raw forms into structures that are more suited to your application Users can also add external routines, including legacy COBOL or C-based programs, to the ETL function list, and load multiple tables on a single pass of an extract. And because the DataMigrator integration engine provides complete data structure transparency, all sources accessed by the servers on your network appear as a set of relational tables – so cross-platform, multiple-database extractions and joins are just a mouse-click away. www.iwaysoftware.com /products/etl_data_migrator.html   (655 words)

dataWarehouse.com Brought to you by DM Review It is important to note that an ETL tool strictly “extracts, transforms and loads.” Separate tools or external service organizations, which may require additional cost, accomplish the work of name and address cleansing and standardization. After a connection is established to the source systems, the ETL tool is used to read, perform simple transformations such as rudimentary cleansing (i.e., trimming spaces), perform data type conversion, convert data formats and load the data into the staging area. Advanced transformations are recommended to take place in the stage to warehouse component and not in the source to stage processing (explained in the next section). www.datawarehouse.com /article?articleId=3186&searchTerm=cowdrey   (2548 words)

Intelligent Enterprise Magazine: Surrounding the ETL Requirements This perspective is especially relevant to the ETL team that may be handed a data source with content that hasn't really been vetted. In general, the ETL team and data modelers need to work closely with the end-user application developers to determine the exact requirements for the final data handoff. The profiling step not only gives the ETL team guidance as to how much data cleaning machinery to invoke, but protects the ETL team from missing major milestones in the project because of the unexpected diversion to build a system to deal with dirty data. www.intelligententerprise.com /showArticle.jhtml?articleID=51201335   (2340 words)

Enterprise Systems Data Warehouse Extract Transform and Load Now that we understand their format, we can explore the architecture of the extract, transform and load (ETL) process needed to get the data into a clickstream data warehouse. By having a separate log file server, data extraction can be performed continuously without impacting the query performance of the clickstream data warehouse. Since the staging schema closely resembles the actual clickstream data warehouse schema, loading is straightforward and can be done in batches or even as a continuous trickle feed of new data, as long as queries are always properly constrained by date and time. www.esj.com /Columns/article.aspx?EditorialsID=72   (637 words)

The Oracle 10g Data Pump API Speeds Up the ETL Process Long, slow extracts and complex transformations are a fact of life, and it's up to you to minimize the impact on your system. Thus, it's time-consuming to extract, transform, and load these data from the other systems into your main instance. Of course, if you have the access and authority to push for changes in the source systems, you can speed up the ETL process by speeding up the extract at the source end, and even by providing the data in a format that needs less transformation. www.devx.com /dbzone/Article/30355?trk=DXRSS_LATEST   (780 words)

icdar,Seventh International Conference on Document Analysis and Recognition Volume I In this work we have used the Radon transform as the basis to extract the representation of graphic images as it permits to globally detect lineal singularities in an image, which are the most important source of information in these images. The image obtained after applying Radon transform can be used directly to describe the symbol, or can be used to extract new and compact descriptors from it, which will also be based on lineal information about the image. Content-based retrieval and recognition of graphic images requires good models for symbol representation, able to identify those features providing the most relevant information about the shape and the visual appearance of symbols. csdl.computer.org /comp/proceedings/icdar/2003/1960/01/196010195abs.htm   (1485 words)
