Extracting, Transforming and Loading (ETL Tools) in India

Summary – How important are these three functions of database that are collectively called us ETL tools. Let us read about it.

 Body – When three database functions are joined together to develop one single tool that could be used for excel operations, it is called as Extract,Transform and Load software or we can also term as ETL tools. This is basically used to extract data from one sheet and use it into another data with transformation and load enhancements.

 
Just imagine how difficult it would have been to analyze the reports created through a survey or questionnaire without comparing one data with another. These ETL tools save time and efforts to calculate multiple data’s at once. Not only this we can also check the relevancy and errors into the data while comparing it with the previous reports.
 
Now lets discuss about all these three functions “Extract, Transform and Load” separately, by which we would be able to understand their use and importance in today’s world.

1.Extract – This is the process of extracting or reading data from the sheet or database. This function also helps in copying the data from the database which is ready to be used in any form.

2.Transform – This is a process that helps in extracted data to be converted into a new form, which is required by the new database. For example you have extracted a data from an older database and now wants to use it into a new database then transformation tools would be requited. Transformation usually occurs by using tables, rules, or by combining the data.

3.Load – As the term clearly says it all. This tool helps in processing of writing the data into a new database.

 
So if we combine the above three functions, we would find that ETL tools are used to migrate one data form into a newer data form which can be done for up-gradation of the software, redeveloping of the software, building new functions, changing the UI etc.


When we speak about ETL Reporting  then there is a very important term that also needs to be understood, i.e Data Warehouses. To design and develop an ETL tool is considered as time consuming and resourceful operation. The use of ETL in data warehousing projects has been increased off lately. Primarily ETL tools are used in Data Warehousing and the most used tools under this category is Oracle. But many small companies have also developed a tool that is easy to understand and use, plus is cost-effective as compared to the oracle warehouse builder tool. However Oracle is not an ETL tool but is used for ETL operations thus leading to the overall cost of the project very high. Thus it is recommended to use the tools available in the market by various SME companies.
