H1: Git
1.1 Version control
Met version control kan men de versie van een bepaald bestand manipuleren. Zo is
het mogelijk om terug te gaan naar een vorige versie of om tussen verschillende
versies te springen.
Het trackt alle wijzigingen die aan het bestand worden gemaakt.
1.2 Source code control
Source code control is een vorm van version control en het heeft veel voordelen voor
programmeurs:
• Efficiënt bestanden delen en samenwerken in dezelfde code.
• Aanduidingen van de persoon die de code heeft aangepast en wat er exact is
veranderd.
• Verschil tussen de staat van de code zien
• Zien welke bestanden het vaakst werden aangepast.
• Altijd een back-up beschikbaar omdat de code steeds in de cloud wordt
opgeslagen.
2.3 Twee types systems
Er bestaan twee soorten systemen:
