زبان پرسمان - ویکیپدیا، دانشنامهٔ آزاد
زبانهای پرسمان[۱] (به انگلیسی: Query languages) یا زبانهای پرسمان داده (به انگلیسی: data query languages) با کوتهنوشت (DQLs) نوعی زبان رایانهای است، که از آن برای ساخت پرسمان در پایگاههای داده و سیستمهای اطلاعاتی استفاده میشود.
یک پرسمان[۱] یا کوئری (به انگلیسی: query) یک درخواست دقیق برای بازیابی اطلاعات از یک پایگاه داده یا سیستمهای اطلاعاتی است.
انواع زبان پرسمان
[ویرایش]به صورت گسترده، زبانهای پرسمان را میتوان براساس آنکه آیا آنها «زبان پرسمان پایگاهداده» اند، یا «زبان پرسمان بازیابی اطلاعات» میباشند، طبقهبندی کرد. تفاوت به این شرح است:
- یک زبان پرسمان پایگاه داده سعی میکند پاسخهای حقیقی به سوالهای واقعی بدهد.
- درحالیکه یک زبان پرسمان بازیابی اطلاعات سعی میکند اسنادی بیابد که شامل اطلاعاتی مرتبط با یک پهنهی تحقیقی میباشند.
