java connectivity to database

1. JDBC
OVERVIEW

2. 1. JDBC (Java Database
Connectivity):
 Explanation of JDBC and its role in connecting
Java applications to databases like MySQL.
 Understanding JDBC drivers and their types
(Type 1, Type 2, Type 3, Type 4).
 Writing Java code to establish connections,
execute SQL queries, and handle results
using JDBC APIs.

3. 2. Connection Pooling:
 Introduction to connection pooling and its
importance in improving database connection
performance.
 Integration of connection pooling libraries like
Apache Commons DBCP or HikariCP with
Java and MySQL.
 Configuration and optimization of connection
pool settings for better resource utilization.

4. 3. PreparedStatement and SQL
Injection Prevention:
 Explanation of PreparedStatement and its
advantages over Statement for executing
parameterized SQL queries.
 Understanding SQL Injection vulnerabilities
and techniques to prevent them using
PreparedStatement.
 Writing secure Java code to interact with
MySQL by utilizing PreparedStatement for
query execution.

5. 4. Transactions and Transaction
Management:
 Overview of database transactions and their
ACID properties (Atomicity, Consistency,
Isolation, Durability).
 Writing Java code to initiate, commit, and
rollback transactions using JDBC.
 Handling transaction management scenarios
like nested transactions, savepoints, and
transaction isolation levels.

6. 5. ORM (Object-Relational
Mapping):
 Introduction to ORM frameworks like
Hibernate and JPA (Java Persistence API).
 Mapping Java objects to relational database
tables and vice versa using ORM annotations
or XML mappings.
 Performing CRUD (Create, Read, Update,
Delete) operations on MySQL databases
using Hibernate's session or JPA
EntityManager.
