L’objet, c’est un \u00e9l\u00e9ment fondateur de l’informatique moderne<\/strong>.<\/p>\n

On programme objet, on peut analyser avec une approche objet…<\/p>\n

Mais d’abord, c’est quoi ce truc ?<\/strong><\/p>\n

L’approche objet est \u00e0 la base une \u00e9volution \u00ab\u00a0naturelle\u00a0\u00bb des techniques de programmation<\/strong>.<\/p>\n

Un peu d’histoire :<\/p>\n

L’informatique a commenc\u00e9 avec des langages \u00ab\u00a0barbares\u00a0\u00bb, ou en tout cas de bas niveau : assembleur, cobol…<\/p>\n

Puis sont venus les langages fonctionnels et structur\u00e9s<\/strong>.<\/p>\n

Fini les GOTO, et bienvenue aux variables locales !<\/p>\n

Cela a constitu\u00e9 une avanc\u00e9e fondamentale<\/strong> :<\/p>\n

Le programme est 1000 fois plus lisible, 1000 fois plus r\u00e9utilisable<\/strong>.<\/p>\n

Il y a eu d’autres pistes explor\u00e9es : les langages de type Intelligence Artificielle (Prolog), les langages purement fonctionnels (Camel & co), …<\/p>\n

Et puis il y a eu l’objet.<\/p>\n

Derri\u00e8re l’objet, il y a plusieurs id\u00e9es fondatrices :<\/p>\n

L’une des id\u00e9es est de se dire que les structures de donn\u00e9es sont cl\u00e9es<\/strong>, et finalement plus centrales, plus stables que les fonctions<\/strong>.<\/p>\n

Bref, le truc objet a bien pris, et la plupart des langages modernes sont objets<\/strong> : C#, Java, PHP…<\/p>\n

\u00e7a, c’est la grandeur des objets.<\/p>\n

Mais les objets auraient pu aller \u00e0 pleins d’autres endroits.<\/p>\n

Il y a eu ainsi de magnifiques projets de bases de donn\u00e9es objets<\/strong> (O2<\/a> mon amour \ud83d\ude09 ).<\/p>\n

J’en parlais ce soir avec mon amis Hubert<\/a>, qui de son c\u00f4t\u00e9 a travaill\u00e9 sur un projet d’OS objet<\/strong>.<\/p>\n

A ce propos, Microsoft devait int\u00e9grer une base de donn\u00e9es objet<\/strong> \u00e0 la place du file system de Vista… Projet abandonn\u00e9.<\/p>\n

Tout \u00e7a, c’est la d\u00e9cadence de l’objet !<\/p>\n

Il n’y a pas de base de donn\u00e9es objet s\u00e9rieuse sur le march\u00e9.<\/p>\n

Les OS ne sont pas objets.<\/p>\n

Le file system est tr\u00e8s loin d’\u00eatre remplac\u00e9 par une base objet…<\/p>\n

Pourquoi \u00ab\u00a0tant de haine\u00a0\u00bb ?<\/p>\n

C’est une histoire qui me fascine d’autant plus qu’elle me ram\u00e8ne \u00e0 ma propre histoire : dans les ann\u00e9es 90, j’avais mont\u00e9 un projet de bases de donn\u00e9es objet, persuad\u00e9 que c’\u00e9tait l’avenir.<\/p>\n

On peut dire que pour les bases de donn\u00e9es, cela n’a pas pris parce que ce que les gens attendent d’une base de donn\u00e9es, c’est de stocker des donn\u00e9es, et pas tellement de savoir comment elles sont structur\u00e9es.<\/p>\n

Je n’adh\u00e8re pas \u00e0 l’argument, parce que cet argument aurait tr\u00e8s bien pu jouer contre les langages de programmation…<\/p>\n

Je pense qu’en fait, il y a s\u00fbrement une part de hazard l\u00e0 dedans… Et si \u00e7a se trouve, on aura bel et bien de belles bases de donn\u00e9es objets dans les ann\u00e9es \u00e0 venir ! N’oublions pas que cette histoire est en cours d’\u00e9criture !<\/p>\n","protected":false},"excerpt":{"rendered":"
