JDBC

 


What is JDBC?

JDBC is the Java Database Connectivity, which is a Java API that allows Java applications to interact with databases. It provides a standard interface to connect to relational databases and execute SQL queries.


Connection : Creating a Connection is like building the bridge – it establishes a link between your program and the database. 🌉


Statement : 💼: A Statement is the tool that allows you to execute SQL queries on the database through your established Connection. It's the driver ready to embark on the journey, executing instructions like querying, updating, or deleting records. 🛣

example:The connection is the road, and the statement is the driver. Just as a driver needs a road to navigate, a statement needs a connection to execute queries on the database


💼: Statements come in different forms, such as regular Statements, Prepared Statements, and Callable Statements, each with its unique magical properties to interact with the database.


CreateStatement : 💼: It's the basic tool to execute SQL queries on a database. Think of it as the driver ready to navigate the road, setting the stage for interactions with the database. 🛣

💼: Creating a Statement is essential for tasks like querying, updating, or deleting records in the database.


PreparedStatement : 💼: It's like having a GPS navigator for your SQL queries. Prepared Statements allow you to pre-compile SQL queries, enhancing efficiency and security. 🗺

💼: Parameters can be set in a Prepared Statement, making it a powerful tool for executing the same query multiple times with different values.


CallableStatement : 💼: Callable Statements go beyond regular SQL queries; they are designed for executing stored procedures in the database. 🔄

💼: Think of it as having a clear set of instructions for specific tasks, ensuring structured and organized interactions with the database. 🧭

Understanding SQL in MySQL: From DDL to DCL

  📦 MySQL is a widely-used relational database management system (RDBMS) that uses Structured Query Language (SQL) to manage and manipulate data. SQL is divided into several categories, each serving a specific purpose: DDL, DML, DQL, TCL, and DCL. 1. Data Definition Language (DDL) DDL commands are used to define and manage database structures such as tables, indexes, and schemas. The main DDL commands include CREATE, ALTER, DROP, and TRUNCATE. ⭐ CREATE: This command creates a new database object. CREATE TABLE students ( id INT PRIMARY KEY, name VARCHAR(100), age INT ); ⭐ ALTER : This command modifies an existing database object. ALTER TABLE students ADD COLUMN email VARCHAR(100); ⭐ DROP : This command deletes an existing database object. DROP TABLE students; ⭐ TRUNCATE : This command removes all records from a table without deleting the table itself. TRUNCATE TABLE students;

Exploring Data Formats: JSON, XML, CSV

  ➡ JSON, XML, and CSV are commonly used for data interchange! in RESTAPI's ok but what is data interchange!?? ⤵ ➡ data interchange format like a language that computers use to talk to each other. Just as people use different languages to communicate, like English, Spanish, or Chinese, computers use specific formats to exchange information. These formats make sure that data is structured in a way that both computers can understand, whether they're sharing data over the internet, saving it to a file, or passing it between different parts of a program. JSON(JavaScript Object Notation) : it used for representing structured data in RESTful APIs, particularly in Spring Web applications. Spring provides excellent support for JSON processing through libraries like Jackson, ➡ It is like writing down information in a way that's easy for both humans and computers to understand. It's a simple and readable format that's often used for transmitting data between a web server ...

SQL vs NoSQL

  📦 SQL vs NoSQL 📑 🌟 SQL (Structured Query Language) :Organized and follows strict rules (like books on specific shelves). ▶ Think of it like a well-organized library where every book is placed neatly on a specific shelf. ▶ The shelves are labeled with categories, and each book has a specific spot. ▶ You have a strict rule about how books are organized, and every book follows this rule. 🌟 NoSQL (Not Only SQL) : Flexible and can be organized in different ways (like books on shelves, in piles, or in boxes). ▶ Now, imagine a different kind of library where books are placed in different ways. ▶ Some books are on shelves, some are in piles, and some are in boxes. ▶ There are no strict rules about where to put the books. You can organize them in whatever way makes sense at the time. 🎨 Use Cases: 🎢 SQL: Good for situations where you need to keep things very organized and follow rules, like keeping track of a catalog of books in a library. 🎡 NoSQL: Good for situations where you ne...
