Extract-Transform-Load or ETL is a process in which data is loaded from a source system to the data warehouse. Data is usually extracted from the OLTP database, transformed into the required form so as to match the schema and finally loaded into the data warehouse database. ETL testing is ideal for companies dealing majorly with historical data such as financial, travel, etc.
When implementing an Extract, Transform, and Load (ETL) system for business intelligence, the major risk lies in rushing a data warehouse into service without testing it thoroughly. Outsource2india's ETL testing process ensures that all your systems and data are tested systematically for bugs, errors, and vulnerabilities before the data is integrated and made available.
Our highly talented team of software testers is well trained to work on different technologies and testing environments. Some of the key ETL testing services we provide include:
This type of testing is carried out to check whether the data values which have been transformed are the expected data values or not. This ensures data compatibility and prevents any risk of data loss.
This testing is done on data when it is being moved to the production systems. The data in the production system must be in correct order without which the whole process of transfer would become useless. Our services ensure that the data does not compromise the production systems' integrity.
Under this service, we check if the data extracted from the older repository or application is the same as the data present in the new application. These can be automatically generated hence saving considerable development time for your data warehouse developers.
A metadata repository containing all information about source, target, mappings, transformations, etc. is extremely important in ETL. Outsource2india's metadata testing involves data length check, testing data type, and index/constraint check, allowing you to maintain a steady control over your organization's overall information systems.
This testing aggregates actual data between the source and the target for columns with simple transformation or no transformation. This is done to check if all the expected data is loaded on to the target from source in a correct manner.
This is a type of testing which ensures that the data is loaded correctly and transformed as expected. Our testers are experts at testing the accuracy and completeness of your data, and follow time-tested procedures in order to ensure complete data integrity.
In many cases data transformation cannot be done by writing just one SQL query and comparing the output with the target. In our transformation testing process, multiple SQL queries are written to run each row and verify the transformational rules.
We provide data quality tests which include syntax and reference tests. This is done to avoid any kind of error caused due to different scenarios such as incorrect order numbers or dates during the business process.
We provide GUI/navigation testing support to check if the GUI aspects or navigation of the front end are functioning properly, and generate an exhaustive report for the same.
We provide incremental ETL testing services to check the data integrity of new and old data with the addition of the new data. It also verifies that the updates and inserts are being processed as expected during the incremental ETL process.
