مع النمو المتسارع لحجم البيانات المخزنة في الأنظمة السحابية تصبح الحاجة إلى المعالجة الفعالة للبيانات أمراً حرجاً و ملحاً. يقدم هذا البحث دراسة أهم خصائص نظم إدارة قواعد البيانات الآتية: Hive و SQLMR و MariaDB Galera. إن Hive هو نظام إدارة قواعد بيانات سحابي. و SQLMR هو نظام هجين يعتمد على الدمج بين قدرات النظم السحابية و التقليدية. أما Galera MariaDB فهو من نظم إدارة قواعد البيانات التقليدية المطورة لمواكبة الخصائص السحابية. تم في هذا البحث عرض أهم التطويرات التي تمت على تلك النظم و مقارنة أدائها في معالجة البيانات بالاعتماد على قياس زمن تنفيذ عمليات استعلام مع تغير حجم البيانات، و ذلك من أجل التعرف على أداء تلك الأنظمة عملياً و معرفة متطلبات تطويرها للوصول إلى نظام إدارة بيانات أمثلي، و لمساعدة المستخدمين في اختيار نظام قواعد البيانات الذي يحقق متطلباتهم من ناحية التوافرية و التدرجية.
With the rapid growth of the size of the data stored in the cloud systems, the need for
effective data processing becomes critical and urgent. This research introduces a study of
the most important characteristics of databases management systems: Hive, SQLMR, and
MariaDB Galera. Hive is a cloud database management system. SQLMR is a hybrid
system, which depends on the integration between the cloud and traditional systems
capabilities. While MariaDB Galera is a traditional database management system
developed to cope with the cloud characteristics. In this research, we show the most
important developments that have been on those systems, and then we compare their
performance in data processing based on the execution time of query operations with the
change of the volume of data. That is to identify the performance of those systems
practically and to know the developing requirements for access to optimized data
management system, and to help users in the selection of the database system that achieves
their requirements in terms of availability and scalability.
