One of the most reinvented concepts in programming is the associative array. It consists of a collection of attribute-value pairs. It's fundamentalness - yet obviousness - has led to it having dozens of names. Here are some of them.
associative-array := [ attribute-value-pair* ]
attribute-value-pair := (attribute, value)
| Language | Associative Array | Attribute-value pair | Attribute | Value |
|---|---|---|---|---|
| JSON | object | member | name | value |
| JavaScript | object | property | property name | value |
| Python | dict | key-value pair | key | value |
| PHP | array | key-value pair | key | value |
| Perl | hash | key | value | |
| C | struct | member | ||
| C++ | std::map | key | value | |
| Excel | Sheet | row | column | cell |
| ADO | recordset | record | field | property |
| SQL | table | row | column | value |
| Lua | table | key | value | |
| NoSQL | key-value store | key | value |
