زبان پرسمان

**زبان‌های پرسمان**  یا **زبان‌های پرسمان داده**  با کوته‌نوشت (DQLs) نوعی زبان رایانه‌ای است، که از آن برای ساخت پرسمان در پایگاه‌های داده و سیستم‌های اطلاعاتی استفاده می‌شود.

یک **پرسمان** یا **کوئری**  یک درخواست دقیق برای بازیابی اطلاعات از یک پایگاه داده یا سیستم‌های اطلاعاتی است.

## انواع زبان پرسمان
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.
