JSON Query Language

What Does JSON Query Language Mean?

JSON query language (JAQL) is any software suite that is used in conjunction with databases for querying, parsing or even forming Javascript Object Notion (JSON)-based documents.


JSON is a standard data-interchange format for creating documents similar to XML and not an outright type of database, so there really is no single standard query language. Instead, there are many independent languages developed by different organizations for manipulating and parsing JSON documents.

Techopedia Explains JSON Query Language

JSON materialized because of a perceived need for stateful, real-time client-server communication without the need to use browser plug-ins such as Java applets or Flash as was the norm in the late 1990s and early 2000s.

It was originally based on a subset of JavaScript, but is a language-independent data format, and as such it has no formal query language, but there are many different implementations at a query language for JSON.

Query languages compatible with JSON:

  • JAQL – functional data processing and query language for JSON and Big Data applications. Originally started as an open source project at Google but was picked up by IBM to be used as the primary data processing language for their Big Data software, Hadoop.
  • JSONiq – functional programming and query language designed for declarative query and can transform collections of data into JSON, XML or unstructured textual formats.
  • XQuery – has the same function as the above but was made specifically for XML but also works with JSON and other formats.
