Reviews summary

تنظيف متغيرات السلسلة باستخدام sql: أساس عملي

وفقًا للمتعلمين، تقدم هذه الدورة تدريبًا قويًا وعمليًا في تنظيف متغيرات السلسلة باستخدام لغة الاستعلام البنيوية (SQL). يبرز العديد من الطلاب وضوح الشرح وتنظيم المحتوى كأحد نقاط القوة الرئيسية، مما يجعل المفاهيم المعقدة سهلة الفهم. كما تُشيد الدورة بـالمشاريع التطبيقية والأمثلة العملية التي تساعد في ترسيخ المعرفة وتقديم مهارات قابلة للتطبيق مباشرة. بينما يرى بعض المتعلمين أنها ممتازة للمبتدئين، يشير آخرون إلى أنها قد تكون سطحية لمن يبحث عن تغطية متعمقة أو تحديات متقدمة، مما يجعلها أنسب لمن لديهم معرفة أساسية بـ SQL أو يبحثون عن مراجعة شاملة.

توفر هذه الدورة أساسًا متينًا لمستخدمي SQL الجدد أو أصحاب الخبرة البسيطة.

"دورة ممتازة للمبتدئين الذين يرغبون في فهم كيفية تنظيف البيانات باستخدام SQL."

"اعتقد أنها مناسبة للمستوى المتوسط، وقد يجد المبتدئون صعوبة بسيطة في البداية."

"يبدو أن الكورس مصمم خصيصًا للمبتدئين في مجال تنظيف البيانات بـ SQL."

توفر الدورة أمثلة عملية ومشاريع تطبيقية قيمة لتعزيز الفهم.

"استفدت كثيرًا من الأمثلة العملية. الأمثلة عملية ومباشرة."

"المشاريع التطبيقية كانت مفيدة جدًا لتطبيق ما تعلمته."

"المشروع النهائي كان تطبيقًا جيدًا للمفاهيم التي تعلمتها."

المحتوى واضح ومنظم ويسهل متابعته واستيعابه للمتعلمين.

"دورة ممتازة... المحتوى منظم بشكل جيد وخطوات سهلة المتابعة."

"المدرب شرح بطريقة واضحة جدًا ومبسطة، مما جعل المفاهيم المعقدة سهلة الفهم."

"الشرح كان واضحًا والخطوات منطقية. كل شيء واضح ومباشر."

يجد بعض المتعلمين أن سرعة الشرح سريعة في أجزاء معينة من الدورة.

"وجدت أن سرعة الشرح سريعة بعض الشيء في بعض الأقسام، مما يتطلب إيقاف الفيديو والعودة إليه."

تفتقر إلى تغطية متعمقة لحالات الاستخدام المعقدة والتحديات المتقدمة.

"لو كان هناك المزيد من التحديات المتقدمة، لكان الكورس أفضل."

"كان من الممكن أن تكون التغطية أعمق قليلاً لبعض حالات الاستخدام المعقدة."

"الكورس سطحي إلى حد ما. لا يقدم تفاصيل كافية حول التعامل مع أنواع بيانات السلاسل المعقدة."

"ليست شاملة بما يكفي لمن يبحث عن معرفة متعمقة في تنظيف البيانات."
