In my previous posts, I explained about Data Subset and Data Masking. In this post we will focus on the topic of Test Data Refresh.
So what is Test Data Refresh? It is the process of loading / refreshing the Test Database with the latest data from the Production database or any other data source.
What are the Challenges in Test Data Refresh
- Diverse data targets
- Much like the Production data sources, Test data targets can also be across databases and different file systems. The data needs to be in sync across these targets
- Test DB can already contain data
- If it is an existing system, already the Test Database will contain older data. Steps should be taken to carefully overwrite the data without losing the data integrity.
- Test DB downtime
- During the time of test data refresh, it might be necessary to bring down the test environment in order to accommodate the refresh.
