-friendly horizontal scalability, replication, and fault tolerance.* SQL supports JSON. A few years ago, many SQL Systems added XML document support. Now, as JSON becomes a popular format for data interchange, SQL vendors are adding JSON-type support. Based on the current flexible programming process and the normal uptime requirements of the web infrastructure, we need the support of structured data types. Oracle 12c, PostgreSQL 9.2, VOLTDB, and other JSON-enabled databases typically have better

A relational database (RDBMS) has been a mainstream database model for over One-fourth centuries.
