What are the Impacts JSON bring in technology

This is the 3rd post of my series article "Is it time to revisit PostgreSQL and MySQL with JSON support"

There are following impacts json bring in the technologies.

NoSQL Document database became popular, mongodb was among one of lucky database vendor.
Technology found JSON as an alternate to xml for data interchange on platform independent.
Technology found a supporting for RDBMS to keeping variety of data specially non-structured data in one environment and module.
Data explosion and big data came into the platform. The cost on data keeping has rapidly decreased over the last several years, which has resulted in the rapid expansion of genomic data acquisition. While new database technologies have become common to manage big data.
Schema less architecture given support in fast and rapid application development.
Polyglot persistence increases the technology surface area enough that it can become quite difficult to monitor, manage, develop, and operate such a diverse set of databases.
Polyglot Persistence is a fancy term to mean that when storing data, it is best to use multiple data storage technologies, chosen based upon the way data is being used by individual applications or components of a single application. Different kinds of data are best dealt with different data stores.
