Database Essentials: Concepts, Normalization, SQL Functions & Joins
Database Applications: Uses, Advantages, and Disadvantages
A database application is software used to store, manage, and access data easily.
Common Database Applications
- Banking: Stores customer and transaction details.
- E-commerce: Manages products, orders, and user information.
- Hospitals: Keeps patient records and doctor schedules.
- Schools: Stores student marks and attendance.
- Airlines: Handles bookings and flight details.
Advantages of Database Systems
- Reduces data redundancy (repetition).
- Provides secure
C Data Structures: Stack, Binary Tree, Queue Implementations
C Stack Implementation: LIFO Data Structure
A stack is a fundamental linear data structure that follows the Last-In, First-Out (LIFO) principle. This means the last element added to the stack is the first one to be removed. Stacks are commonly used in various computing scenarios, such as function call management, expression evaluation, and undo/redo functionalities.
Key Stack Operations
- Push: Adds an element to the top of the stack. If the stack is full, it results in a “Stack Overflow” error.
- Pop:
Voice-Based Data Analysis and Automated Knowledge Generation
Automated Fun Fact Generation from Wikipedia
Introduction: Problem Definition
- There has been recent interest in providing fun facts.
- In this paper, the authors demonstrate how fun facts can be mined from superlative tables in Wikipedia.
- The content is dynamic, meaning it is updated over time.
Key Contributions
- The authors show how to identify a large number of relational tables and attributes within each table from Wikipedia that are an excellent source for generating fun facts.
- They propose a templated

Stable Matching Problem Proof Strategies
To demonstrate a matching’s stability, a common approach is proof by contradiction. Assume an instability exists between a man (m) and a woman (w’). Then, consider two scenarios: (1) m and w’ interacted at some point, or (2) they never interacted. In both cases, the assumption of instability leads to a contradiction, thereby proving stability.
To prove an algorithm yields a specific matching (e.g., all men paired with their best valid partners), we again use

C Program Structure & Core Components
The basic structure of a C program consists of several key components, each serving a specific purpose. Here’s a breakdown of each part:
Preprocessor Directives
These are commands processed before actual compilation. They are used to include external libraries or define constants.
Example:
#include <stdio.h>This directive includes the standard input/output library, allowing the use of functions like

Process Management: RPC Exactly Once Semantics
Your ID: ceQ62 – Data Set [3, 5, 17, 6, 2]
MAX = 17
MAX % 8 = 1 – Answered Questions: q1, q2, q3, q4 (cyclically from q1)
RPC Exactly Once Semantics Explained
Yes, the “exactly once” semantics can still be achieved even if the *acknowledgment (ACK)* sent back to the client is lost.
Sequence of Events:
Client sends request to the server.
Server executes the procedure and sends back ACK.
ACK is lost in transmission.
Client, not receiving ACK, resends the request.
