1) Pour une base de données repartie avec des SGBD hétérogènes, quelle est l’approche qui demande moins de traducteurs pour la conversion des données et des requêtes depuis un modèle vers un autre? Approche pivot.
2) Est-ce qu’on peut avoir deux objets identiques et égaux dans une BDO ? justifier
Non, car chaque objet a son propre identificateur.
3) Suivant l’approche fragmentée pour l’organisation du dictionnaire de données, expliquer comment la manipulation des données distantes

Stoke’s Theorem is a fundamental statement in multivariable calculus that relates the surface integral of the curl of a vector field over a surface to the line integral of the vector field around the boundary of the surface. This is a powerful tool that bridges gap between line integrals and surface integrals. Stokes' Theorem is a higher-dimensional version of the two-dimensional Green's Theorem, and it is important in many fields of physics and engineering, including fluid dynamics,...
Valores individuais:
Valores individuais são as crenças e ideias de cada pessoa sobre o que é desejável e digno de aprovação. Eles moldam as nossas atitudes, levando-nos a aceitar ou rejeitar, aproximar ou afastar, e a fazer escolhas e tomar decisões em relação a objetos, a outras pessoas, a ações e a diversas situações. Essencialmente, são esses valores que definem quem somos e o que pretendemos ou devemos fazer.

The Multifaceted Mirror: An Analysis of the Title "The Good Woman of Szechwan"Bertolt Brecht’s choice of "The Good Woman of Szechwan" as his play's title is far more than a simple descriptor; it’s a meticulously crafted, multi-layered reflection of the play’s central themes and Brechtian principles. At first glance, it presents a seemingly straightforward paradox: how can one be "good" in a system that forces moral compromise? Yet, a deeper analysis reveals its ironic, interrogative, and ultimately
Q.Explain the construction and working of Ruby laser with the help of energy level diagram.
Ruby is a crystal of aluminum oxide Al2O3 in which chromium Cr3+ ions are added as impurity (0.5%).So its colour is pink. Ruby rod of 4cm in length and 0.5 cm in diameter is generally used. The end faces of rod are strictly made parallel, grounded and silver polished. The one end face is fully reflecting and other end is partially reflecting. A helical Xenon flash tube is surrounded the ruby rod with high

# 🌱 **Vermicomposting: Stages and Precautions**
---
## 🧾 **Introduction:**
Vermicomposting is a **bio-oxidative process** in which **earthworms** convert **organic waste** into **nutrient-rich compost** known as **vermicompost** or **worm castings**. This method is eco-friendly, cost-effective, and highly efficient in recycling organic matter. It not only helps in waste management but also improves soil health, fertility, and crop yield naturally.
The process depends on the activity...
