Note also a type called an internal JDBC driver - a driver embedded with JRE in Java-enabled SQL databases. It is used for Java stored procedures . This does not fit into the classification scheme above, although it would likely resemble either a type 2 or type 4 driver (depending on whether the database itself is implemented in Java or not).
The JDBC type 4 driver, also known as the Direct to Database Pure Java Driver, is a database driver implementation that converts JDBC calls directly into a vendor-specific database protocol. Written completely in Java , type 4 drivers are thus platform independent .
Programmers usually use such a bridge when a given database lacks a JDBC driver, but is accessible through an ODBC driver. Sun Microsystems included one such bridge in the JVM, but viewed it as a stop-gap measure while few JDBC drivers existed (The built-in JDBC-ODBC bridge was dropped from the JVM in Java 8 [31]). Sun never intended its bridge ...

Tabular Data Stream (TDS) is an application layer protocol used to transfer data between a database server and a client. It was initially designed and developed by Sybase Inc. for their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server.
If a request for data (a SQL Select statement) is sent to the database and a result set is returned, the connection is open but not available for other operations until the client finishes consuming the result set. Other databases, like SQL Server 2005 (and later), do not impose this limitation. However, databases that provide multiple ...
DBeaver is a SQL client software application and a database administration tool. For relational databases it uses the JDBC application programming interface (API) to interact with databases via a JDBC driver. For other databases it uses proprietary database drivers.
Azure SQL Database, Azure SQL Managed Instance, and SQL Server on virtual machines rely on client-side connection pooling implemented by libraries such as ADO.NET and JDBC. The database engine does not manage pooling, as it is entirely handled at the client level.
