بسبب ازدياد انتشار البيانات والاستخدام الواسع لمواقع التواصل الاجتماعي والتطبيقات المختلفة والتي تعتمد بشكلٍ رئيسي على العلاقات المعقّدة والمترابطة بين العديد من الكيانات التي تحتاج لنماذج محددة من قواعد البيانات من أجل القدرة على تخزينها واسترجاعها بكفاءة وسرعة، لذلك لم تعُد قواعد البيانات العلاقاتية (Relational Databases) تفي بالغرض أو تؤدّي جميع المتطلّبات التي تحتاجها العديد من الأنظمة الموزّعة والمواقع والتطبيقات البرمجية التي تحوي قواعد معطيات كبيرة، والتي بدورها تحتاج لسرعة وسهولة في الوصول إليها وإجراء العمليات المناسبة ضمنها. تشرح هذه الورقة بشكلٍ مختصر التحدّيات التي واجهت قواعد المعطيات العلاقاتية والطريقة التقليدية في التعامل مع البيانات، والأسباب التي أدّت للجوء إلى ما يُسمّى قواعد المعطيات غير العلاقاتية NoSQL (Not Only SQL)، بالإضافة للتطرّق إلى نظرية CAP وبعض أنواع NoSQL، مع التركيز على GraphQL كأحد تقنيات النّوع Graph.
The huge growth in the data storing and the wide use of social networks and applications that depend mainly on complicated and interrelated relations between entities which need specific models of databases to store and retriev quickly and effectively, the relational databases are no longer adequate in distributed systems and websites that deal with big data which have to be accessible and operable. This paper explains briefly the challenges of relational databases and the reasons that led to emergence the non-relational databases (NoSQL), in addition to CAP theorem and some of NoSQL types, specially GraphQL

The mentioning relational database system term has become a synonymous to
database system, but the monopoly of big companies that work in database systems field
has become an obsession for persons who work in this field, because of the high costs o
f
this systems. For this reason the concerns turn towards the advanced technique : the native
XML database systems which are free or most of them are open source systems because of
the increasing dependency on XML files and particularly in transporting data between
different applications and the availability of collections of related files. This has
summoned towards a system to manage and organize them, for this reason the NXDs
appeared. The aim of this study is making a comparison between the capabilities of
RDBMS and NXDs in accordance to multiple standards , investing these two techniques
in practical application , make the relevant tests which reflect the use of these techniques
on the suggested application , display the results and give future suggestions.

GIS software provide manual import tools to maps produced on CAD software to be transformed to geo-database. This operation consumes time and effort. The "transformation" however will not be
adequate unless we analyze the relation between CAD and GI
S software in preparing maps. The question raised here if this relation competitive or integrative? This research tries to answer this matter
by studying it from different angles: modeling, spatial feature, scale, spatial analysis and data management. Analyses reveal that this relation isn't competitive at all, but rather integrative, as CAD
software produce technical\design plans, whereas GIS software are dedicated for the production of general and thematic maps. Thus, CAD based spatial data (topographic, cadastral, master plans) could
be "up-graded" to be efficient in GIS environment. However available tools to make this are basically manual, and for that, an automated approach was developed to execute this upgrade from CAD to GIS.
This new approach was applied and evaluated and the output results were satisfactory accurate, time\effort saving, and indeed didn't miss any of CAD layers. This all could be achieved if being conditioned with the approach constrains.
Human dialogue contains evolving concepts, and speakers naturally associate multiple concepts to compose a response. However, current dialogue models with the seq2seq framework lack the ability to effectively manage concept transitions and can hardly
introduce multiple concepts to responses in a sequential decoding manner. To facilitate a controllable and coherent dialogue, in this work, we devise a concept-guided non-autoregressive model (CG-nAR) for open-domain dialogue generation. The proposed model comprises a multi-concept planning module that learns to identify multiple associated concepts from a concept graph and a customized Insertion Transformer that performs concept-guided non-autoregressive generation to complete a response. The experimental results on two public datasets show that CG-nAR can produce diverse and coherent responses, outperforming state-of-the-art baselines in both automatic and human evaluations with substantially faster inference speed.
The topic of the study in this research is one of the
important topics in Number Theory, where did we get
into man techniques and systems related to Diophantus
equations.
