It is a pure Java driver because it completely implemented by the Java programming language 4. Most databases provide at least a type 4 driver. This type includes, for example, the widely used Oracle thin driver. Javatpoint Services JavaTpoint offers too many high quality services. Type 1 drivers are were mostly intended to be used in the beginning, when there were no type 4 drivers all Java drivers. They install inside the Java Virtual Machine of the client. The native code part is targeted at a specific database product i.

Type 3 drivers offer your application the ability to transparently access different types of databases, while type 4 drivers usually exhibit better performance most frequently used in realtime. Timestamp, retaining the time information. For this reason, it is known as thin driver. This driver had very poor performance because of several layers of translation which took place before your program connects to database.

This driver is fully written in Java and it is mainly used for connecting applets with databases. It is most suitable for the web. Driver is a software which connects two dissimilar software components or software and hardware. So, changing the bound value before calling the execute method could change the bound value. Hence it is not suitable for real-time applications.

If a Java application needs to access multiple types of databases at the same time, type 3 is the preferred driver. Since the Bridge driver is not written fully in Java, Type 1 drivers are not portable. Each of these types meets a different application need and also differ in their performance. If the middle-tier server can in turn use Type1, Type 2 or Type 4 drivers. This driver is very fast as it executes less code to communicate. Traversing the recordset may take longer, since the data comes through the backend server. Warnings are silently chained to the object whose method caused it to be reported.
