Historiek = M(UMPS)  M(UMPS) (mid ’60) (Masschusetts general hospital Multi Utility Programming System)  ANSI standaard (einde ’70)  Ontstaan van M implementaties (DSM, DTM)  Enkel nog gecommercialiseerd en geevolueerd door InterSystems  Programmeertaal  Data opslag in Globals (boomstructuur)

Post-relational database Caché Deel 1

1. De storage manager Multi-Dimensional Storage Manager = Geoptimaliseerd voor performantie = Opslag van complexe datastructuren

Complexe data-structuur: ^Globals Set ^Global = “fruit” fruit ^Global = ^Global gedraagt zich als een gewone type-less variable…

(2) peer Complexe data-structuur: ^Globals Set ^Global(1) = “appel” Set ^Global(2) = “peer” ^Global = (1) appel ^Global = (1) appel

(aantal) 45 set ^Global(2, “aantal”) = 45 Subscripts zijn eveneens untyped, en kunnen ook tekst (en dus data !) zijn … ^Global = (1) appel (2) peer

set ^Global(2, “naam”) = “Jefke” Subscripts zijn eveneens untyped, en kunnen ook tekst (en dus data !) zijn … ^Global = (aantal) 45 (1) appel (2) peer (naam) Jefke

vb. Set ^Global(2, “leverancier”) = “Fruit&co” ^Global = (leveranc.) Fruit&co … (1) appel (2) peer … Global subscripts zijn ook sparse…

Set ^Global(2, “leverancier”, “adres”, “straat”) = “perziklaan” Global subscripts zijn ook sparse… ( ) … (adr.) (abc) ( ) … (lev...) ( ) … ^Global = ( ) … (2) …(2) …(2) …(2) … (str.) = perziklaan

$Data(2, “leverancier) = 11 $Data(2, “leverancier”, “adres”) = 10 Global subscripts zijn ook sparse… ( ) … (adr.) (abc) ( ) … (lev...) ( ) … ^Global = ( ) … (2) …(2) …(2) …(2) … (str.) = perziklaan

^Globals: een n-dimensionele ruimte ^Global naam adres aantal leverancier 1 2 straat = “appel” = “peer” = 45 =“Fruit&co” = “Jefke” = Ø = “perziklaan”

2. Unified Data Architecture (UDA) Multi-Dimensional Storage Manager Caché Object interface  1 dictionary voor 2 access paths  Automatische projectie van definities in beide richtingen.  Geen supplementaire laag voor O/R mapping Caché SQL interface Dictionary

3. Platforms Multi-Dimensional Storage Manager Caché Object interface Caché SQL interface DictionaryDictionary Platforms   Database = 1 uitwisselbaar physisch bestand
