3RI Technologies is offering Best ETL Testing Training in Pune, ETL Testing ensures that the data loaded from a source to the destination after the business transformation is correct. This includes reviewing data in various intermediate phases used between source and destination. ETL stands for Extract-Transform-Load.
The biggest advantage of an ETL tool is that it provides a visual flow of system logic. Each ETL tool differentiates these operations, but even the least responsive user interfaces can be compared to custom systems consisting of stored procedures, SQL and operating system scripts, and a handful of other technologies. Ironically, some ETL tools are not a practical way to print out the otherwise attractive self-documentation.
ETL tools were developed for the specific problem of populating a data warehouse. Although they are just tools, they provide the development team with a metadata-driven structure. This is especially useful for teams building their first ETL system.
Many of the self-developed ETL systems I've evaluated are fragile: they have too many operational issues. ETL tools provide functions and procedures for operating and monitoring the ETL system in production. You can certainly design and build a well-instrumented hand-coded ETL application, and the operational capabilities of the ETL tool are not yet mature. Nevertheless, it becomes easier for a data warehouse/business intelligence team to build on ETL.
We want you to be able to right-click on a number in a report and see exactly how it was calculated, where the data was stored in the data warehouse, how it was transformed when the data was last updated, and from which source System or systems underlying the numbers. Because there are no ETL standards that hand-coded systems could match, we need to rely on ETL tool vendors to provide this functionality. Unfortunately, only a few have done so far.
Most companies estimate that they only analyze up to 15% of the data - Forrester Research. According to research and markets global Big Data Analytics Market Reaches around $ 41 Billion in nearly 4 years. An ETL developer in the US can earn more than $ 100,000 a year. Businesses today need to work with data in multiple formats extracted from multiple sources. All this makes ETL testing even more important. The extraction, transformation, and loading of data must be checked and any deviations remedied. Therefore, there is a need for testers in ETL and data warehousing domains. This training can help you learn ETL tests, and gives you the skills and confidence to take on good jobs in some of the largest companies in the world.
The future of ETL testing is very promising. ETL tools such as IBM Infosphere Information Server, Informatica PowerCenter, Oracle Data Integrator, Microsoft SQL Server Integrated Service, SAS, etc. are in high demand in the industry and popularity. Its scope will increase in the future.
Studies show that employers are looking more for proper and efficient ETL testers than for other job profiles. According to LinkedIn and Naukri, there are more than 14,000 ETL testers in India. The salary of an ETL tester varies from organization to organization and also depends on many years of experience. At present, the average salary that the ETL tester in India has is between 2.5 L / A and 10 L / A. There is also no salary limit for the right candidate. There are many job title choices and many multinational companies are looking for the best candidate with knowledge of ETL testing. Her professional career includes various roles, depending on her years of experience.
