JSON vs. Python vs. RPM Package Manager vs. Wing Python IDE Comparison Chart

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.

The RPM Package Manager (RPM) is a powerful package management system capable of building computer software from the source into easily distributable packages; installing, updating, and uninstalling packaged software; querying detailed information about the packaged software, whether installed or not; and verifying the integrity of packaged software and resulting software installation. The package’s metadata is stored in the RPM header. The header is a binary data structure that stores single pieces of data in tags. Each tag has a pre-defined meaning and data type. These are not stored in the header itself but need to be known by the code reading the header. In the header, the tags are only referred to by their number. Each tag is either of a plain scalar type or is an array of one of these types. While not enforced by the type system the RPM code assumes that tags belonging together have the same number of entries.
