JDBC(Java Database Connectivity)

• Database Access: JDBC allows Java applications to access and interact with relational databases.

• Database Independence: JDBC provides database independence, meaning the same Java code can be used to connect to different databases without modification.

• Standard API: JDBC offers a standard API for database connectivity, making it easier for developers to work with databases in Java applications.

• Connection Management: It handles connection establishment, management, and termination between Java applications and databases.

Before learning JDBC (Java Database Connectivity), you should have a solid understanding of the following skills:

1. Core Java: Proficiency in core Java programming is essential, including knowledge of object-oriented programming concepts, data types, control structures, and exception handling.

2. SQL: Familiarity with SQL (Structured Query Language) is necessary, including understanding of basic SQL syntax, database schema design, data manipulation (CRUD operations), and SQL queries.

3. Database Concepts: Understanding of fundamental database concepts such as relational database management systems (RDBMS), normalization, indexing, transactions, and database architecture is beneficial.

By learning JDBC (Java Database Connectivity), you gain the following skills:

1. Database Interaction: Ability to connect Java applications to databases and perform database operations such as querying, updating, inserting, and deleting data.

2. Data Access: Understanding of how to retrieve and manipulate data from relational databases using SQL queries executed through JDBC.

3. Database Transactions: Knowledge of managing database transactions, including committing, rolling back, and setting transaction isolation levels to ensure data consistency and integrity.

4. Error Handling: Proficiency in handling exceptions and errors that may occur during database interactions, ensuring robustness and reliability of JDBC applications.
