In today’s world just as organizations need to manage their physical assets they also need to manage the data their organization produces.This is when the ETL tools play a vital role and assist the organization to do well and remain competent in the market.
ETL stands for Extract, Transform and Load. Just as the name implies, these tools extract data from a given source this could be a proper structured database or a flat file or data from web apps, or it could be as trivial as data from sensors just in the form of 0’s and 1’s. The second step is transforming the data while in transit, which involves making the data readable to performing complex data type conversion to performing arithmetic/logical operations and then finally load the data to a given destination storage.
Some common projects where ETL is a must are :
- Pulling up transactional data (sale + purchase) for company heads to work with and generate visualization reports. This is commonly known as Data Warehousing.
- Migrating data from legacy system to new systems due to change application/platform.
- Data integration that triggered due to corporate mergers and acquisitions.
- ETL could also help in integrating data from third-party suppliers/vendors or partners in the Supply Chain Management Cycles.
This picture depicts how critical ETL tools are in managing data generated throughout your organization.
Which ETL Tool to choose :
Considering the above image, every organization must spend some on R&D to determine which ETL tool they should choose that fits best into their business. Below are some of the criterias any ETL tool must adhere to:
- Data Connectivity: Chosen ETL tool must have the ability to connect to any data source no matter where it is coming from. This is critical!
- Performance: dealing with huge amount of data and transforming definitely requires some great processing capabilities. Hence the ETL tool you choose should be able to scale up with growing data rates.
- Rich Transformation Library: Transforming the data manually requires writing 1000’s of lines of code which is highly prone to errors. So in order to enable smooth data transformation, your ETL tool must extend a rich library of functions and packages which are also as easy as drag and drop facilities.
- Data Quality Check: You can never just pick up the data from a given source and start working on transforming it. Your data is never that clean enough and hence you are not good to go. You will definitely require some data cleaning support from your ETL tool.
- Committed ETL vendor: As the above points mention all the reasons why ETL is a critical process, it is also important to choose a committed ETL vendor who knows in and out about the tool and can provide a good support all throughout the project.
