**Note**: en pratique la partie cliente et la partie serveur sont |
|
41 |
généralement intégrées dans le même processus et communiquent donc |
|
42 |
directement, sans nécessiter des appels distants via Pyro. Il est |
|
43 |
cependant important de retenir que ces deux parties sont disjointes |
|
44 |
et qu'il est même possible d'en exécuter plusieurs exemplaires dans |

des processus distincts pour répartir la charge globale d'un site |

d'entités et de relations, grâce à la bibliothèque `yams`_. C'est |

l'élément central d'une application. Il est initialement défini sur |
55 |
le système de fichiers et est stocké dans la base de données lors de |

la création d'une instance. `CubicWeb` fournit un certain nombres de |
|
57 |
types d'entités inclus systématiquement car nécessaire au noyau |

|

base de toute entité, qui est sa clef, est l'eid |

67 |
les relations sont binaires : par convention on nomme le premier terme |
0 | 68 |
d'une relation son 'sujet' et le second son 'objet'. |
69 |
||
70 |
*type d'entité final* |
|
71 |
les types finaux correspondent aux types de bases comme les chaînes |
|
72 |
de caractères, les nombres entiers... Une propriété de ces types est |
|
73 |
qu'ils ne peuvent être utilisés qu'uniquement comme objet d'une |
|
74 |
relation. Les attributs d'une entité (non finale) sont des entités |
|
75 |
(finales). |
|
76 |
||
77 |
*type de relation finale* |
|
78 |
une relation est dite finale si son objet est un type final. Cela revient à |
|
79 |
un attribut d'une entité. |
|
80 |
||
81 |
*entrepôt* |
|
82 |
ou *repository*, c'est la partie serveur RQL de `CubicWeb`. Attention à ne pas |
|
83 |
confondre avec un entrepôt mercurial ou encore un entrepôt debian. |
|
84 |
||
85 |
*source* |
|
86 |
une source de données est un conteneur de données quelquonque (SGBD, annuaire |
|
87 |
LDAP...) intégré par l'entrepôt `CubicWeb`. Un entrepôt possède au moins une source |
|
88 |
dite "system" contenant le schéma de l'application, l'index plein-texte et |
|
89 |
d'autres informations vitales au système. |
|
90 |
||
91 |
*configuration* |
|
92 |
il est possible de créer différentes configurations pour une instance : |
|
93 |
||
94 |
- ``repository`` : entrepôt uniquement, accessible pour les clients via Pyro |
|
95 |
- ``twisted`` : interface web uniquement, communiquant avec un entrepôt via Pyro |
|
96 |
- ``all-in-one`` : interface web et entrepôt dans un seul processus. L'entrepôt |
|
97 |
peut ou non être accessible via Pyro |
