JDBC (Java Database Connectivity) JDBC (Java Database Connectivity) is a standard Java API that enables Java applications to connect and interact with relational databases. It provides methods to execute SQL queries, retrieve results, and perform database operations such as inserting, updating, and deleting data. Supports SQL operations such as SELECT, INSERT, UPDATE, and DELETE. Works with multiple relational databases like MySQL, Oracle, PostgreSQL, and SQL Server. Uses JDBC drivers to establish communication between Java applications and databases. JDBC Architecture The JDBC API provides the standard interfaces, while the JDBC driver implements the database-specific communication required to interact with the database. Components of JDBC: 1. Application: It can be a Java application or servlet that communicates with a data source. 2. JDBC API: It allows Java programs to execute SQL queries and get results from the database. Some key components of JDBC API include Interfaces like D...

Module1 Generative AI (GenAI) is the latest subtype of AI that broadly describes Machine Learning (ML) models or algorithms. Difference Between Traditional AI and Generative AI Traditional AI Generative AI AI is used to create intelligent systems that can perform those tasks which generally require human intelligence. It generates new text, audio, video, or any other type of content by learning patterns from existing training data. The purpose of AI algorithms or models are to mimic human intelligence across wide range of applications. The purpose of generative AI algorithms or models is to generate new data having similar characteristics as data from the original dataset. Overview of Generative Adversarial Network GAN stands for Generative Adversarial Network, and it is a class of artificial intelligence algorithms used in machine learning and deep learning for generating dat...

What is Blockchain? A Blockchain is a digital ledger of transactions that is secure, immutable, and decentralized. It consists of a chain of blocks and each block contains a secure group of transactions of money, bitcoins, contracts, property, etc. without any need for third-party middle-man such as central authorities, banks, government, etc. Transactions are verified by a network of computers. Once a block of information is created in the chain, it can’t be changed or deleted. This makes the blockchain very secure and trustworthy. It is a software protocol, it never runs without the internet. Why Do We Use Blockchain? There is no need for centralized authorities to verify our transactions. Blockchain makes it decentralized and secure. The security is maintained by cryptographic processes performed by p2p users, through the process called Data mining. Some of its important features are: Secure Transparent Tamper-proof Peer-to-peer transaction Bitcoin is the most popular cryptocurrency...

Use Case Diagram for Bank ATM System Automated Teller Machine (ATM) also known as ABM (Automated Banking Machine) is a banking system. This banking system allows customers or users to have access to financial transactions. These transactions can be done in public space without any need for a clerk, cashier, or bank teller. Working and description of the ATM can be explained with the help of the Use Case Diagram . Some scenarios of the system are as follows. Step-1: Customer Authentication 1. The user is authenticated when enters the plastic ATM card in a Bank ATM. 2. Then enters the user name and PIN (Personal Identification Number). 3. For every ATM transaction, a Customer Authentication use case is required and essential. So, it is shown as include relationship. Step-2: Bank ATM System 1. User checks the bank balance as well as also demands the mini statement about the bank balance if they want. 2. Then the user withdraws the money as per their ...
