Overview of JDBC: What is JDBC, Importance of JDBC in Java applications, JDBC Architecture and API components

Setting Up the Environment: (Installing and setting up JDK, Configuring a database (e.g. MySQL), Setting up a development environment (Eclipse, IntelliJ, or VS Code), Adding JDBC driver libraries to the project)

Understanding JDBC Drivers:(Types of JDBC drivers (Type 1, Type 2, Type 3, Type 4), Loading and registering JDBC drivers)

Connecting to a Database: (JDBC URL, Username, and Password, Establishing a connection using DriverManager, Handling SQLException and understanding error codes)

Basic CRUD Operations: (Create: Inserting records using PreparedStatement, Read: Querying records using Statement and ResultSet, Update: Modifying records using PreparedStatement, Delete: Removing records from the database)

Prepared Statement vs Statement: (Differences between Statement and PreparedStatement, Using PreparedStatement for dynamic queries, Preventing SQL Injection with PreparedStatement)

Batch Processing: (Introduction to batch processing, Adding multiple queries to a batch, Executing batch updates for performance optimization)

ResultSet: (Navigating the ResultSet (next, previous, absolute, relative), Working with different types of ResultSet (forward-only, scroll-sensitive, scroll-insensitive), Retrieving data from a ResultSet, Updating a ResultSet and reflecting changes in the database)

Introduction to Transactions: (What is a transaction, ACID properties-Atomicity, Consistency, Isolation, Durability)

Managing Transactions in JDBC:(Auto-commit mode in JDBC, Manually handling transactions with commit() and rollback(), Savepoints in transactions, Handling transaction isolation levels (READ_UNCOMMITTED, READ_COMMITTED, REPEATABLE_READ, SERIALIZABLE)

Callable Statement: (Calling stored procedures and functions, Passing IN and OUT parameters, Handling CallableStatement results)

Handling Large Objects (LOBs): (Storing and retrieving BLOBs (Binary Large Objects) and CLOBs, (Character Large Objects), Managing large data efficiently in JDBC)

Introduction to Connection Pooling: (What is connection pooling, Benefits of using a connection pool

Implementing Connection Pooling: (Setting up Apache DBCP for connection pooling, Configuring connection pool parameters (e.g., pool size, timeout))

Error Handling in JDBC: (Understanding SQLException and SQLWarning, Handling SQL exceptions, Logging and debugging database operations, Resource management (closing connections, statements, and result sets), Avoiding common pitfalls (e.g., SQL Injection, inefficient queries))

Preventing SQL Injection: (Understanding SQL Injection attacks, Using PreparedStatement to prevent SQL Injection, Validating and sanitizing user input)

Packaging and Deploying JDBC Applications: (Creating executable JARs with JDBC dependencies, Configuring databases for production environments, Best practices for deploying JDBC applications in production)

Maintaining and Scaling JDBC Applications: (Monitoring database connections and performance, Scaling applications to handle larger databases, Planning for database migrations and upgrades, Analyzing and optimizing query performance, Efficient use of indexes and query optimization, Profiling and monitoring JDBC performance)

What is Hibernate

• Overview of Object-Relational Mapping (ORM).

• Benefits of using Hibernate over JDBC.

Setting Up Hibernate

• Installing Hibernate and setting up a basic Java project.

• Adding Hibernate dependencies (Maven/Gradle).

• Configuring Hibernate with hibernate.cfg.xml.
