Java and JDBC: Working with a Database

Java and JDBC: Working with a Database

Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. It is a Java-based data access technology used for Java database connectivity. It is part of the Java Standard Edition platform, from Oracle Corporation. It provides methods to query and update data in a database, and is oriented towards relational databases.

This repository contains some examples of how to work with a database using Java and JDBC. Below are listed the topics covered:

• Inserting and removing data from database;
• SQL Injection and Prepared Statement;
• Transaction: commit and rollback;
• Connection Pool and Datasources;
• Isolating data access and DAO (Data Access Object);
• Relationships, optimizing N+1 and ORM tools.
