To load the data from the feed ETL process is used. That company will receive a data feed from the other company. If CRM company needs some data from the company who is managing the Billing. Lets take example of Telecommunication project where billing is managed by one company and CRM is managed by other company. Means not a single vendor is managing everything. The big organizations always gives different application development to different kind of vendors. These kind of integration projects need the ETL process to extract the data,transform the data and load the data. Obviously the data source for the different organizations may be different.We need to integrate the data from one organization to other organization. Now a days big organizations are acquiring small firms. To make this simple the ETL tools are very useful in which the coding is simple as compare to PL SQL or T-SQL code.So ETL process i very useful in Data migration projects. If user wants to write the code of ETL it is very time consuming process. If the organization is managing the data in oracle 10 g previously and now organization wants to go for SQL server cloud database then there is need to migrate the data from Source to Target.To do this kind of migration the ETL tools are very useful. If user wants the historical data as well as current data in the shopping mall first step is always user needs to follow the ETL process.Then that data will be used for reporting purpose.ĮTL tools are widely used in data migration projects. The simple example of this is managing sales data in shopping mall. Its data sources might be different.User needs to fetch the data from multiple heterogeneous systems and load it in to single target system which is also called as data warehouse.Īs The ETL definition suggests that ETL is nothing but Extract,Transform and loading of the data This process needs to be used in data warehousing widely. The Data warehouse data is nothing but combination of historical data as well as transactional data. The most common example of ETL is ETL is used in Data warehousing.User needs to fetch the historical data as well as current data for developing data warehouse. In this section i would like to give you some important ETL examples. I have explained different ETL Definition in previous section. As the name suggested ETL stands for Extract Transform and Load.Just like the name applies ETL tool Extracts data from the source.Transforms the data while in transit and then it loads the data in to Specified database.ĮTL is nothing but Extract,Transform and Loading of the data from multiple heterogeneous data sources to a single or multiple sources.ĮTL is nothing but Extraction,Transformation and Loading of the data. Just like a physical assets Organization needs to manage its data assets also. There are many situations where user needs to use the physical data in digital way. If you see that in real world the person always deals with different type of data. In this article I would like to explain about ETL Definition and ETL process in brief. In my previous articles I have explained about the differen t Business Analytics concepts.
