Introduction the number system is a fundamental concept in mathematics and computer science, and it forms the basis for arithmetic and data representation. Here’s a quick overview: 1. Decimal System (Base-10) 2. Binary System (Base-2) 3. Octal System (Base-8) 4. Hexadecimal System (Base-16) Conversion Between Systems Applications Understanding these systems helps in grasping how computers […]
Introduction of Non-linear Data structures Non-linear data structures are types of data structures where elements are not arranged in a sequential order. Unlike linear data structures such as arrays, linked lists, stacks, and queues, non-linear data structures do not follow a sequential order and instead have a hierarchical or interconnected arrangement of elements. This allows […]
Introduction of Queues A queue is a fundamental data structure in computer science that follows the First-In-First-Out (FIFO) principle. This means that the first element added to the queue will be the first one to be removed. Queues are used in a variety of applications, such as managing tasks in a printer spooler, handling requests […]
Introduction of Stack A stack is a fundamental data structure in computer science that operates in a Last-In-First-Out (LIFO) manner. This means that the last element added to the stack is the first one to be removed. Stacks are used in various applications, such as evaluating expressions, backtracking algorithms, and managing function calls. Key Characteristics […]
Introduction to Linked Lists in C A linked list is a fundamental data structure that consists of a sequence of elements, where each element is connected to the next one through pointers. Unlike arrays, linked lists do not have a fixed size, allowing for dynamic memory allocation and efficient insertion and deletion of elements. Key […]
Introduction Data structures are essential concepts in computer science and programming, providing ways to store, organize, and manage data efficiently. When implemented using the C programming language, data structures enable the development of efficient algorithms and systems.Data structures in C are fundamental to organizing and managing data efficiently. By selecting the appropriate data structure, you […]
Classification of Databases: RDBMS,OLAP,NOSQL Databases are classified based on their structure, usage, and purpose. Understanding these classifications is crucial for choosing the right database system to meet specific requirements. Below are the main types of databases: 1. Relational Database Management System (RDBMS) RDBMSs are the most common type of database used for structured data. They […]
CURSOR In SQL and PL/SQL, a cursor is a database object that allows you to retrieve and manipulate the result set of a query one row at a time. Cursors are particularly useful when you need to process query results sequentially rather than in a set-based manner. Real-Life Example: A Book and Bookmark Imagine you […]
Introduction to PL/SQL PL/SQL (Procedural Language/SQL) is an extension of SQL (Structured Query Language) used in Oracle databases. It combines the data manipulation power of SQL with the procedural capabilities of a programming language. PL/SQL is designed to work seamlessly with SQL, making it a powerful tool for writing complex queries, managing transactions, and controlling […]
SQL and Benefits of SQL SQL (Structured Query Language) is a powerful language used for managing and manipulating relational databases. It is the standard language for interacting with database management systems (DBMS) like MySQL, PostgreSQL, Oracle, Microsoft SQL Server, and many others. SQL allows users to perform various operations on the data stored in relational […]
