هدف هذا البحث إلى دراسة الأدوات المفهومية المستخدمة في النمذجة المفهوميـة لتطبيـق مـا، لمعرفة فائدة التوسع في تلك الأدوات من أجل تصميم قاعدة معطيات علاقاتية فعالة. قمنا لهذه الغاية بمعالجة مثالين تطبيقين جرى خلالهما استخدام مخططين مفهوميين لإنـشاء قاعـدة معطيات علاقاتية. و خلصنا إلى نتيجة رئيسة هي أنه تتحقق فائدة التوسع في الأدوات المفهومية من أجل تصميم قاعدة معطيات علاقاتية، عندما يتم تطبيقه في الأداة المستخدمة لبناء قاعدة المعطيات. و نظـراً لأن المرحلـة المفهومية لقاعدة المعطيات يجب أن تتسم برأينا بالوضوح و البساطة، لا ينصح بتطبيق التوسع في حالـة نمذجة المخططات المفهومية للأنظمة الضخمة ضمن قيد زمني محدد.
This paper aims to study the Conceptual Tools used in Conceptual Modeling of Database, so that Benefit of Extending these Tool used in Effective Relational Database Design could be found out. In this study, we investigated two application examples, through which two Conceptual diagrams were used to build Relational Database. The main result of this study was, the benefit from the extending the Conceptual Tools for designing a Relational Database could be achieved when this extension to Tools used in building is applicable to the Database. Since the Conceptual Modeling stage of the Database, has to be simple and clear, the extension is not recommended for modeling Conceptual diagrams of large systems, which has time limits.

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 effectivel
y, 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
This study tried to stand on the phenomenon of Altarnum ،performance ،as
reflected in this phenomenon ،how to perform text linguistic and linguistic diversity of the
means ،which may be the satiation of an articulation or subsequent prolongation or
modifying and deletion.
The study concluded that Altarnum is a kind of audible performance which is
dominant in poetry. It is based on prolongation a and rewind ،to achieve homonymy during
the long tidal articulation or the use of suffix often Al- Tanween ،Altarnum ،is not limited
to the Tanween of Altarnum ،but achieved in some types of diversity in other kinds of Al-
Tanween. In Altarnum ،using Al-Tanween is legal even if it contradicts with other
grammarians' opinions ،because of Nun's value rhythmic grainy ،and systematic musical
frequencies.
The study also concluded that Altarnum which is different from
Solomon(chanting) ،which is nothing more than raising the voice without homonymy ،
which seems to replace the "Maddah" with "Noan" or bind the end of speech Soothing.

The research aims to study how to add new components to Multisim database. Or
how to model a component using the programing language C++ , to use this new
component later in designing and making electronic circuits and devices.
Multisim has built-
in models for most types of devices, , the study aims to lay the
foundations and method for modeling of electronic items which is not located within the
Multisim program database, (or present with different values) , and that we need while
using this program in the modeling and simulation process for a given circuit.
Code modeling method has been proposed to reach this goal; this method relies on
the behavior of the device or the modeled component.
The study shows how to create a Code model for a specific capacitor that has
different values to those existing within the database and add to it.
Modern Natural Language Processing (NLP) makes intensive use of deep learning methods because of the accuracy they offer for a variety of applications. Due to the significant environmental impact of deep learning, cost-benefit analysis including carb
on footprint as well as accuracy measures has been suggested to better document the use of NLP methods for research or deployment. In this paper, we review the tools that are available to measure energy use and CO2 emissions of NLP methods. We describe the scope of the measures provided and compare the use of six tools (carbon tracker, experiment impact tracker, green algorithms, ML CO2 impact, energy usage and cumulator) on named entity recognition experiments performed on different computational set-ups (local server vs. computing facility). Based on these findings, we propose actionable recommendations to accurately measure the environmental impact of NLP experiments.
