SQL
SQL (Structured Query Language; oʻzbekcha: Tuzilmali soʻrov tili)[1] [2][3] – maxsus tillar sirasiga kiradi. SQL domenga xos til hisoblanib, dasturlashda keng foydalaniladi. Yana ham aniq aytadigan boʻlsak, ushbu til orqali foydalanuvchilar maʼlumotlar omborini boshqarish tizimida saqlanadigan maʼlumotlarni boshqarishlarida kerak boʻladi. Bu tilni dastlab kashf etishgan vaqtida SQL tilini relatsion algebra hamda uch tomonlama relatsion hisoblashlarga moʻljallashgan edi. SQL tili dunyo tamaddunida 1974-yilda paydo boʻldi. Bu oddiy voqea emas, balki "buyuk kashfiyot" ham edi. Uning muallifi Donald D. Chamberlin va Raymond F. Boyce hisoblanadi. Shuningdek, Chamberlin nafaqat SQL tilini yaratgan, balki IBM sistemasi X Query orqali ham mashhur.
