list advantaes of dbms ?
Reduces Data Redundancy
DBMS avoids duplication of data. The same data is stored only once, which saves storage space.
Improves Data Consistency
When data is updated in one place, it is automatically updated everywhere, so the data remains consistent.
Data Security
DBMS provides security by allowing only authorized users to access or modify the data.
Data Sharing
Multiple users can access and share the same database at the same time.
Data Integrity
DBMS ensures that
L1 – EARTH SHAPE, GRAVITY & SYSTEMS
Earth rotates → centrifugal force → equatorial bulge + polar flattening → oblate ellipsoid. Equatorial r = avg+7km, polar r = avg−7km, avg r = 6371km. Ellipsoid assumes uniform mass distribution but Earth's mass is uneven due to: ice sheets growing/melting, mantle plumes,
variable crust thickness, density differences between oceans and continents.
Gravitation = force caused only by mass attraction. Gravity = gravitation + centrifugal force. Gravity

Aujourd’hui, parlons des réseaux sociaux et de leur impact sur les enfants. Vous voyez de quoi je parle, n’est-ce pas ? Dans les écoles, dans les transports ou même à la maison, les écrans occupent une place de plus en plus importante dans la vie des plus jeunes. Pour être honnête, cette situation me laisse souvent inquiet, car il devient difficile d’ignorer les effets de cette présence constante. En effet, de nombreux enfants passent plusieurs heures
La place de la femme dans la société reste toujours un sujet très discuté qui provoque plusieurs débats. Certains pensent que la femme est capable de rivaliser avec l’homme dans tous les domaines, tandis que d’autres soutiennent le contraire.
Peut-on vraiment considérer la femme comme un être inférieur ?
Il est vrai que la femme a longtemps été perçue comme faible et soumise. Dans le monde du travail et dans le domaine professionnel, elle subit souvent des injustices et même du machisme.

Engineering materials are substances used to manufacture machines, tools, structures and devices. Materials science studies the relationship between structure, properties, processing and performance of materials and explains why materials behave in a particular way. Materials engineering
Is technology neutral?How does technology shape society?How do algorithms influence media?
Intro- Technology is often described as a neutral tool whose impact depends only on how people use it. However, scholars in science and technology studies argue that technologies are never neutral because they are shaped by social values, political interests, and economic goals. This essay argues that technologies embed power relations and social priorities, as demonstrated by algorithmic media systems that
1. What is C++ Programming? Explain it’s features and applications. C++ is a general-purpose programming language developed by Bjarne Stroustrup. It is an extension of the C language and supports both procedural and object-oriented programming concepts. It is used to develop high-performance applications.
Features of C++ 1. Object-Oriented Programming – C++ supports classes and objects to organize code in a structured way. 1. Encapsulation – It allows binding data and functions together...
