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 ...
When a Java application needs a database connection, one of the DriverManager.getConnection() methods is used to create a JDBC Connection. The URL used is dependent upon the particular database and JDBC driver. It will always begin with the "jdbc:" protocol, but the rest is up to the particular vendor.
Schematic of the Native API driver. The JDBC type 2 driver, also known as the Native-API driver, is a database driver implementation that uses the client-side libraries of the database. The driver converts JDBC method calls into native calls of the database API. For example: Oracle OCI driver is a type 2 driver.
It handles the SQL request and converts it into a request that the individual database system understands. According to Microsoft, "After SQL Server 2012, the ODBC driver will be updated for the most recent server features, including Microsoft Windows Azure SQL Database, and released as the Microsoft ODBC Driver for SQL Server."

Microsoft SQL Server Compact (SQL CE) is a discontinued relational database produced by Microsoft for applications that run on mobile devices and desktops. Prior to the introduction of the desktop platform, it was known as SQL Server for Windows CE and SQL Server Mobile Edition. It includes both 32-bit and 64-bit native support. [1]
Spark SQL provides a domain-specific language (DSL) to manipulate DataFrames in Scala, Java, Python or .NET. [16] It also provides SQL language support, with command-line interfaces and ODBC/JDBC server. Although DataFrames lack the compile-time type-checking afforded by RDDs, as of Spark 2.0, the strongly typed DataSet is fully supported by ...
