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.
