We have already seen that JDBC DriverManager can is used to get relational database connections. But if it comes to actual programming, we want more than just connections.Most of the times we is looking for loose coupling for connectivity so, we can switch databases easily, connection POOling for transaction management and distributed systems support.

The Java Database Connectivity (JDBC) API is a series of interfaces that enable Java programmers to access the database, and the interfaces of each developer are not exactly the same. After years of JDBC with Oracle, I've accumulated a lot of skills that enable us to better perform system performance and achieve more functionality.

In Oracle, fields of the lob (large object, large object) type are increasingly used. This type of field has a large capacity (up to 4 GB of data), and a table can have multiple fields of this type, which is flexible, applicable to business areas with a large data volume (e.g., archives, etc ). However, although the storage capacity of fields such as long and long raw is not small (up to 2 GB), a table can have only one field of this type, it is rarel

, when I was working on a project, I needed to access data from other databases. I could only use the ODBC driver on the Windows platform. The cost of doing so is that you can only deploy applications on the Windows platform, rather than using Unix-like systems. This is like being shackled. My requirement is to be cross-platform, so there is only one option-JDBC.
This is not surprising. In today's enterprise applications, only
