Understanding JDBC: The Architecture and Underlying Concepts Before we delve deeper into JDBC, it’s crucial to understand its architecture and the underlying concepts. This will give you a better grasp of how JDBC works, and why it’s such an essential tool for Java developers. The JDBC API:...
The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. DriverManager is considered the backbone of JDBC architecture. DriverManager class manages the JDBC drivers that are installed on the system. Its getConnection() method is used to establish a connection ...
This architecture helps java program or application to directly communicate with the database. It needs a JDBC driver to communicate with a specific database. Query or request is sent by the user to the database and results are received back by the user. The database may be present on the...
Moves to the cloud are aplenty, but picking the perfect one can be hard. The best kind of cloud architecture for your business deals with all the software and hardware components. Ineffective cloud computing planning can result in more overhead, less scalability, and therefore a lower return on...
Figure 1: JDBC 3.0 Connection Pooling Architecture When an application makes a connection by callingDataSource.getConnection()on aPoolingVendorDataSourceobject, thePoolingVendorDataSourceobject performs a lookup in the connection cache to determine if aPooledConnectionobject is available. If one is avail...
JDBC ArchitectureThe JDBC API supports both two-tier and three-tier processing models for database access. Figure 1: Two-tier Architecture for Data Access. In the two-tier model, a Java applet or application talks directly to the data source. This requires a JDBC driver that can communicate ...

In previous tutorial we had implemented Apache Camel + Spring SQL Component Example for inserting and retrieving records from MySQL. In that example we had made use of Spring XML configuration. In this tutorial we will be making use of Spring Boot and Apache Camel JDBC Component for inserting ...
In the above example, we import the dependencies that are required to establish the connection with the database such as SQL. connection, SQL.DriverManger etc. After that, we import the class as shown. Here we also mentioned a connection string with connection parameters such as DriverManager....
In this article, we explored three different ways to convert a JDBCResultSetto a JSON object. Each approach can have its own uses. What we choose depends on the required structure of the output JSON object and possible limitations on the dependency size, for example. ...
