ETL Extraction, transformation, and loading.

ETL refers to the methods involved in accessing and manipulating source data and loading it into target database.

The first step in ETL process is mapping the data between source systems and target database(data warehouse or data mart).

The second step is cleansing of source data in staging area.

The third step is transforming cleansed source data and then loading into the target system.

Note that ETT (extraction, transformation, transportation) and ETM (extraction, transformation, move) are sometimes used instead of ETL.


Glossary of ETL Source System :

A database, application, file, or other storage facility from which the data in a data warehouse is derived.

Mapping: The definition of the relationship and data flow between source and

target objects.

Metadata Data that describes data and other structures, such as objects,

business rules, and processes. For example, the schema design of a data warehouse is typically stored in a repository as metadata, which is used to generate scripts used to build and populate the data warehouse. A repository contains metadata.

Staging Area A place where data is processed before entering the warehouse.


Glossary of ETL(Cont..) Cleansing

The process of resolving inconsistencies and fixing the anomalies in source data, typically as part of the ETL process.

Transformation The process of manipulating data. Any manipulation beyond

copying is a transformation. Examples include cleansing, aggregating, and integrating data from multiple sources.

Transportation The process of moving copied or transformed data from a source

to a data warehouse.

Target System A database, application, file, or other storage facility to which the

"transformed source data" is loaded in a data warehouse.

What is Talend ..? Talend is the first provider of open source data integration software.

Main product is Talend Open Studio.

After three years of intense research and development investment the first version of that software was released in 2006.

It is an Open Source project for data integration based on Eclipse RCP(Rich Client Platform) that primarily supports ETL-oriented implementations and is provided for on-premises deployment as well as in a software-as-a-service (SaaS) delivery model.

Talend Open Studio is mainly used for integration between operational systems, as well as for ETL (Extract, Transform, Load) for Business Intelligence and Data Warehousing

Talend Open Studio is the most open, innovative and powerful data integration solution on the market today.
