1. The entire testing industry community of the world is looking out for newer methods of testing.And optimizing their cost and efforts. Now, every method has its problems. 
   Similarly, test data management(TDM) used to optimize the experimental data also creates particular challenges at times.These problems must be known to be able to handle them properly. 
2. What Is TDM?
   The most important thing before we go into the details of problems faced, is to know more about test data management (TDM).This is nothing but an efficient way of managing test data – the data used as input in any test.
   The test data is accomplished by providing decent quality and quantity of data to the test teams at and in the given time and ambiance. This is how test data management works.
   Importance of Test Data Management
3. Test data management is used in both functional testing and NFT (non-functional testing). The reason why it has become crucial in the testing community is that it prevents massive losses for companies. Further, it optimizes test data and the entire testing process.
   Functional and non-functional testing utilizes the method of TDM for efficiency.
4. The Major Challenges Faced By TDM
5. No method is entirely perfect. Neither is test data management. The testing group often faces some major problems while dealing with this comparatively new method of test optimization.
   Some of these challenges presented by test data management to the testing team are listed as under:
6. · Consistency And Validity Of Data: Data does not stay the same forever. It changes. It becomes old and unusable. Unless you keep proper track of your data and keep checking it for its validity regularly, your data testing is bound to fail.
7. · Security Of Data: A lot of applications use private, sensitive data. The security of these data is another challenge.
8. · Poor Quality Of Data And Low Levels Of  Standardization: Different testing teams request various types of evidence at the same time. This can cause a lot of chaos and a lack of standardized data. Plus, the quality of data goes down as well.
9. · Storage Costs:Another problem faced during test data management is the huge cost needed for the storage of data. 
10. Solutions To The Major Problems Faced
11. The data management issues by the testing teams are quite dangerous. However, the following information management solutions can help in solving a lot of them.
    - Always do a regular check of your data quality.
    - Try maintaining a proper database with all relevant information.
    - Try organizing the demands sent out to different testing teams.
