Advantages 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, ensuring consistency.
  • Data Security: DBMS provides security by allowing only authorized users to access or modify data.
  • Data Sharing: Multiple users can access and share the same database simultaneously.
  • Data Integrity: DBMS ensures data accuracy and reliability through

Three Data Decomposition Techniques

1. Functional Decomposition
This is the process of taking a complex process and breaking it down into its individual functions or tasks. It focuses on what the system does rather than how the data is structured. In engineering and software, this results in a hierarchy of functions where the top level is the broad goal and the lower levels are specific operations.
Example: Imagine designing an Automated Teller Machine (ATM).

2. Work Breakdown Structure (WBS)
Widely

Database Normalization

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It divides large tables into smaller tables and establishes relationships between them.

Objectives of Normalization

  • Remove data redundancy (duplicate data).
  • Improve data consistency.
  • Make database structure efficient.
  • Avoid update, insert, and delete anomalies.

Types of Normal Forms

  1. First Normal Form (1NF)
    • Each field contains atomic (indivisible) values.
    • No repeating groups.

1. What is C++ Programming?

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++

  • Object-Oriented Programming: Supports classes and objects to organize code.
  • Encapsulation: Binds data and functions together inside a class.
  • Inheritance: Allows one class to acquire properties of another.
  • Polymorphism: Enables

1. RecyclerView Features and GridView Implementation

RecyclerView Features:

  • View Recycling: Reuses views to improve performance and reduce memory usage.
  • ViewHolder Pattern: Stores item views to avoid repeated findViewById() calls.
  • Flexible Layout: Supports LinearLayoutManager, GridLayoutManager, and StaggeredGridLayoutManager.

GridView Implementation:

GridView gridView = findViewById(R.id.gridView);
String[] languages = {"C", "C++", "Java", "Python", "Kotlin"};
ArrayAdapter<String> adapter = new
