In this digital age, most businesses today find themselves producing and storing a massive amount of data every single day. But data alone cannot help an organization. The potential of all this information is of no use if the organization finds it hard to work on it due to the variety of data sources and their volume. But worry no more as, at Flatworld Solutions, we provide comprehensive and high-quality Data Validation in ETL Testing services so that you don't have to struggle with complex ETL processes anymore.
This is crucial because inaccurately performed ETL testing results in source data not being mapped correctly, which ultimately results in a decisive loss in the EDW (Enterprise Data Warehouse). Hence, it's always advisable to rely on an experienced and efficient ETL testing service provider such as Flatworld Solutions.
ETL, which stands for Extract-Transform-Load is the process of data being loaded from a source system to the data warehouse of a company. In this age of Business Intelligence, such raw data is generated in copious amounts and within a very short time, which is then used for data mining activities, reporting, and analysis, etc. ETL testing, also known as data warehousing testing, is a growing testing sub-segment today owing to the growth of IV & V testing services around the world. ETL testing services are ideal for portfolios that deal with a large amount of historical data such as banks and financial institutions, travel, etc.
Although an important step for efficient data warehousing techniques, inaccurately performed ETL testing can lead to source data not being mapped correctly, essentially leading to a large loss in the EDW (Enterprise Data Warehouse). Flatworld is a leading ETL testing service provider and we specialize in automation techniques which makes it very easy to validate your organization's data while adding flexibility and scalability to your testing processes.
Flatworld Solutions is a leading ETL testing service providing company, and we focus on keeping the data extracted from all relevant data sources intact. This is done using advanced ETL testing tools so that this data can be easily mapped in the necessary data warehouse. To offer the best results we tap the potential of both proprietary and open source.
Some of our data warehouse and ETL testing services include -
Prevention of data loss is very critical and to ensure that source to target testing is done. This testing is carried out to know if the data values that are being transformed are expected data values are not.
A metadata repository is of prime importance in ETL as it houses all information regarding the source, target, mappings, transformations, etc. We excel in data length checks, testing data types, and index/constraint checks. Our services ensure you maintain consistent control over your organization's overall information systems.
Our incremental ETL testing services enable you to check the data integrity of new and old data with the addition of the new data. This also helps in verifying that the updates and inserts are being processed as expected during the incremental ETL process.
A lot of times data transformation is not possible by simply writing only one SQL query and then comparing the output with the target. Through our data transformation testing services, multiple SQL queries are written to run each row and verify the transformational rules.
Most of the time, data warehouses are upgraded so that they remain compliant with upcoming technological changes. At Flatworld, we provide a fully automated application upgrade testing process. This results in saving considerable development and scripting time. Also, we test whether data extracted from an old repository can be easily merged into a new repository and whether there are any significant differences between both.
The production validation ETL testing is a crucial test conducted during the process of moving data into the warehouses and other related production systems. We undertake analyzation of the minutest change so that all the data is transferred correctly and mapped properly. This meticulous work equips you to make correct business-related decisions. Thanks to our automation techniques and our swift management of the already available data and the data of the past, your business never runs gets compromised due to incorrect data.
A business can never afford to ignore navigational and GUI inaccuracies as they can be hazardous. These inaccuracies if not mended on time can waste a lot of time and resources. Hence, we provide navigation/ GUI testing services that scrutinize every facet of the GUI on front-end reports to ensure completeness.
At Flatworld Solutions, being decades old ETL Testing services company, we have developed a highly streamlined process so that our clients across the globe receive the best in the class ETL testing services and Data Warehouse Testing services at the most competitive price and the earliest.
We follow a systematic ETL testing process which includes the following steps -
The entire process starts chalking out the scope of the project. This first step is critical for the testing process as it allows the testers to have a complete understanding of the testing process. We start by designing the data model and defining the business flow. We also evaluate the reporting needs according to the needs of the client. This is important so that the testers fully understand the scope of the project.
Once the scope of the project is determined we do a check of the data count so that the table and column data type is according to the specifications of the data model. We make sure that the check keys are in place and also delete any duplicate data. Any errors here can make a massive impact on the aggregate report and hence, we ensure we follow every step meticulously.
In this stage, we define and design ETL mapping scenarios and create SQL scripts. The mapping document is validated to make sure it has all the necessary information.
The test cases are sent to the client for approval. After receiving a positive response, we conduct a pre-execution check and prepare the data for testing. This pre-execution check is critical to ensure all rules are followed properly.
The test is executed till all exit criteria are met and a report on the bugs is generated. Then based on the report, the bugs are removed.
After the tests are executed, the test results are analyzed effectively. We make sure the test rule is completed and then create a summary report. This summary report is then provided to the client.
After receiving the verification from the client verification, we proceed with test closure.
Our ETL test scenarios cover the length and breadth of the Data warehousing process, thereby ensuring complete data accuracy. This comprehensive testing coverage, therefore, allows you to lower business risk while being able to confidently trust the data generated while making mission-critical decisions. Some of the test case scenarios we use include -
