This enables the Java developers to connect to a database and allows them to perform various tasks like managing responses and queries. In Java JDBC connection, the JDBC acts as an adapter layer that provides adaptability to SQL from Java. It can perform various tasks such as creating, reading, and updating records. The main language used by data architects to perform various tasks related to a relational database is SQL. Although NoSQL has gained popularity over the past decade, relational databases like SQL are still the most commonly used type of datastore. Relationship between SQL (a relational database) and JDBCĪ relational database like SQL is a structured repository that stores records in tables with columns and rows. It works directly with the vendor’s database using a socket connection. JDBC-Net pure Java (Type 3): Type 3 drivers use a three-tier approach to access databases through middleware to change JDBC calls into each database-specific callġ00% pure Java (Type 4): This type of driver is the highest performance driver and is used for databases such as Oracle, IBM, and Sybase. JDBC-Native API (Type 2): This is a driver that utilizes the client-side libraries of the target database, also called a native-API driver. JDBC-ODBC bridge driver (Type 1): This JDBC bridge driver contains a mapping to another data access API, such as ODBC drivers, which requires configuring on each system a Data Source Name (DSN) that represents the targeted database. There are various types of these drivers: JBDC drivers are unique implementation tools used for connecting to a particular database for interaction with the database server. ResultSet: This is used to access the result row-by-row.Statements: This is used to carry out a static SQL statement.Connection: This is an interface or session that houses all the methods to connect to any database.Driver Manager: It manages any required set of JDBC drivers.It also withdraws information associated with driver objects. Driver: This is the interface that controls communication with the database server.The JDBC core comes with the following interfaces and classes: Each of these possesses a unique JDBC driver name, that encodes access request statements, issues commands, and handles result sets obtained from the database.īefore we delve into the detailed processes of creating a JDBC connection with databases like SQL, we have to understand all the concepts, tools, classes, and interfaces involved such as JDBC components, JDBC drivers, as well as the relations between relational databases like SQL and JDBC. More so, it supports various types of relational databases which use SQL (Structured Query Language) such as DB2, ORACLE, and Sybase. The most recent version, which was released in September 2017, was part of Java SE 9. Since then, every new release of JDBC has included updates to both the client-side and server-side packages. In version 2.0, it was added with an optional package that supports server-side connections. Originally, JDBC was intended to be a client-side API that could connect to a data source. The Java JDBC connection in Java API defines all classes that handle various aspects of the database, such as connection details, result sets, and database metadata. JDBC is a Java database API that was created as an industry standard for making connections between Java applications and other databases. Package de. import import import import import import import by the original ODBC (Open Database Connectivity), the JDBC stands for Java Database Connectivity.
