Evolution in technology and increased business competitiveness have mandated organizations to focus on data for effective business outcomes. Organizations are looking at data from multiple sources and channels that could potentially help them better understand their customers’ business needs, in turn helping them make effective decisions to sustain and grow among their competitors.

A major challenge is that customer preferences keep on changing, sometimes faster than one can imagine. Additionally, adopting a service model and being competitive in a constantly changing market is one of the major challenges of the modern industry. Another major challenge is bringing the entire business data and information into a centralized store, which needs significant IT investment and maintenance cost.

Mindtree’s Data Testing Service offerings include - ETL testing for complex DW systems, Big Data testing for the implementation & transformation of Hadoop ecosystems, BI reports testing, advanced analytics testing and enterprise test data management.

The significance of data in the current IT world is indispensable, and Big Data technology initiatives are able to integrate huge volumes of data, store and process in a single centralized platform and allow analysis of the data, thus helping gain meaningful insights that can help in making strategic decisions. Testing such implementations requires highly skilled experts who have a lot of experience.

Test Data Management is one of the major requirements in current data transformation implementations, where production data availability is a big challenge due to sensitive data security. In the absence of production data, test data management helps in creating the requisite data needed by the testing team with sensitive information being obfuscated.
