La plateforme ultime de diagramme en tant que code<\/h2>\n<p>Si vous \u00eates nouveau sur la plateforme, voici un rappel rapide : <a href=\"https:\/\/www.vpascode.com\/overview\/\">VPasCode<\/a> est le centre unifi\u00e9 de texte vers diagramme de Visual Paradigm. \u00c0 la place des outils traditionnels de dessin par glisser-d\u00e9poser, VPasCode adopte une philosophie \u00ab Diagramme en tant que code \u00bb (DaC). Il vous permet de concevoir, maintenir et contr\u00f4ler les versions d&#8217;architectures syst\u00e8me complexes, de diagrammes de flux et de diagrammes de s\u00e9quence \u00e0 l&#8217;aide d&#8217;une syntaxe de texte simple et lisible par l&#8217;humain.<\/p>\n<p>La plateforme est \u00e9quip\u00e9e d&#8217;un \u00e9diteur de code rapide et gratuit sur la gauche et d&#8217;un rendu de diagramme en temps r\u00e9el sur la droite. \u00c9tant donn\u00e9 qu&#8217;elle est con\u00e7ue comme un environnement v\u00e9ritablement int\u00e9gr\u00e9, VPasCode supporte th\u00e9oriquement toutes les normes populaires de texte vers diagramme, y compris les syntaxes compl\u00e8tes PlantUML et Mermaid.

Contrairement aux autres langages que nous supportons, notre nouveau <strong>\u00e9diteur SQL ERD<\/strong> introduit un commutateur de rendu dual unique.<\/p>\n<p>Au-dessus de l&#8217;\u00e9diteur de code SQL dans le panneau de gauche, vous trouverez un menu d\u00e9roulant qui est par d\u00e9faut configur\u00e9 sur <strong>\u00ab Mermaid \u00bb<\/strong>.
