Variables as composite data structures

Variables can be combined into composite data structures. Data structures are useful and common in mainstream programming languages, and they follow commonly recognized patterns which can be documented and re-used.[1][2]

SimpleTable (AoH , AoD)

(aka simpletable_aoh [array of hash])

(aka simpletable_aod [array of dictionary])

This composite data structure is suitable for representing a series of rows and columns in most programming languages.[3] AoH stands for "Array of Hashes"[4]

JavaScript

var mytable_aoh = [
   { "fname":"fred"    ,   "lname":"flintstone"  ,   "age":"33"  ,   "sex":"male"    ,  "motto":"yabbadabbadoo"           }
   ,{ "fname":"wilma"   ,   "lname":"flintstone"  ,   "age":"28"  ,   "sex":"female"  ,  "motto":""                        }
   ,{ "fname":"barney"  ,   "lname":"rubble"      ,   "age":"32"  ,   "sex":"male"    ,  "motto":"hiya fred!"              }
   ,{ "fname":"Fred"    ,   "lname":"Astaire"     ,   "age":"76"  ,   "sex":"male"    ,  "motto":"Dancing is a sweat job"  }
];

PHP

$mytable_aoh = Array(
    Array( 'lname' => 'Simpson'      ,'fname'  => 'Homer' ,'age' => '35' ,'motto' => '_blank_' )
    ,Array( 'lname' => 'Simpson'     ,'fname'  => 'Marge' ,'age' => '34' ,'motto' => '_blank_' )
    ,Array( 'lname' => 'Flintstone'  ,'fname'  => 'Fred' ,'age' => '33' ,'motto' => '_blank_' ) 
    ,Array( 'lname' => 'John'        ,'fname'  => 'Doe' ,'age' => '0' ,'motto' => '_blank_' )   
    ,Array( 'lname' => 'Flintstone'  ,'fname'  => 'Wilma' ,'age' => '29' ,'motto' => '_blank_' )
);

Rows are represented using an unordered sequence of name-value pairs (aka Dictionary, Hash, Object).

SimpleTable (AoA)

(aka simpletable_aos [array of sequence])

This is a table structure suitable for representing a series of rows and columns in most programming languages.[5]

JavaScript

var mytable_aoa = [
   [ "fname"   ,   "lname"       ,   "age" ,   "sex"     ,  "motto"                   ]
   ,[ "fred"    ,   "flintstone"  ,   "33"  ,   "male"    ,  "yabbadabbadoo"           ]
   ,[ "wilma"   ,   "flintstone"  ,   "28"  ,   "female"  ,  ""                        ]
   ,[ "barney"  ,   "rubble"      ,   "32"  ,   "male"    ,  "hiya fred!"              ]
   ,[ "Fred"    ,   "Astaire"     ,   "76"  ,   "male"    ,  "Dancing is a sweat job"  ]
];

Rows are represented using an ordered sequence of values (aka Array, List).
