What Are the Benefits of Using ETL Testing Tools for Data Migration?

To begin with, ETL stands for Extract, Transform and Load. It is the process that includes extracting data from source systems, transforming the information into a data type, then loading the data into a single depository. ETL testing refers to the practice of ensuring, verifying, and qualifying data while eliminating the chances of duplicating records and data loss. To further know about this process, one can visit ETL Testing Online Training.

Types Of ETL Testing

There are nine different types of ETL Testing which are as follows.

• Production validation
• Source to target count testing
• Source to target data testing
• Metadata testing
• Data quality testing
• Performance testing
• Data transformation testing
• Data integration testing
• Report testing

Process Of ETL Testing:

The ETL testing process consists of various steps necessary for building, controlling, and protecting integrated or migrated data.

• Requirement Analysis- This step includes visiting the client's place to understand its requirement and prepare the CRS document.
• Test Planning- It consists of information about future activities such as test selection tools, cost estimation, resource planning, etc.
• Design and Prepare Test Cases- The testing team writes detailed test cases for the various scenarios in this test process.
• Test Execution- This process includes testing and preparing the bug report and reporting it back to the development team.
• Test Closure- These are documents that consist of the closure report of the in-detail analysis of the project and bugs fixes.

Benefits Of Using ETL Testing Tools For Data Migration.

ETL testing tools are highly beneficial for data migration as they help in increasing the query and system performance. In addition, these tools provide timely access to data and result in enhancing quality and consistency. Furthermore, using these tools help in validating and ensuring that the business information is exact, consistent, and reliable. ETL tools keep the whole data migration process transparent and record all the steps in the workflow.

They also ensure repeatability for data migrations and allow you to easily edit data sets and re-run an automated data migration process. Moreover, they come with various useful cleansing functions which help perform complex transformations during data migration. Above all, ETL tools are capable of handling big data effectively and can minimize the chances of data loss in the production process. Many institutes provide ETL Testing Online Course and one can enroll in them to start a career in it. Apart from these, given below are some of the benefits of using ETL tools for Data Migration.

• Reduces Delivery Time- These tools save time by creating workflows using a visual interface with ready-made components. Moreover, it eliminates the need to re-doing work every time some modification in the data is needed.
• Reduce Unnecessary Expenses- It allows you to examine changes quickly on the whole data set. Thus, allowing you to know whenever there is any modification in the records.
• Automate Complex Processes- These tools automate the data migration process and save time, and energy, and result in better delivery. Furthermore, it eliminates the chances of manual work and human error.
• Build Data Quality Feedback Loops- This allows you to automate the error handling by exporting values that don’t adhere to the pre-defined data rules. Thus, helping you in feeding cleaner data to your systems
