JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.

Build flexible, distributed systems that can leverage the entire history of your critical data, not just the most current state. Build them on your existing infrastructure or jump straight to the cloud. Critical insights come from knowing the full story of your data, not just the most recent state. Datomic stores a record of immutable facts, which gives your applications strong consistency combined with horizontal read scalability, plus built-in caching. Since facts are never updated in place and all data is retained by default, you get built-in auditing and the ability to query history. All of this with fully ACID-compliant transactions. Datomic's information model scales to a wide variety of different use cases. With the Datomic Peer library, you can distribute immutable data to your application nodes to provide in-memory access to your data. Or, take advantage of the client library to create lightweight nodes for your microservice architectures.
