Fast-changing application environments require a flexible mechanism for storing data and passing data between different application tiers. As it turns out, JSON (Java Script Object notation) is an important technology for moving, interactive applications that reduces the overhead of pattern design and eliminates the need for data conversion. DB2 NoSQL JSON enables developers to write applications using the JSON-oriented popular query language created
