What is ODBC in SQL Server?

An ODBC driver uses the Open Database Connectivity (ODBC) interface by Microsoft that allows applications to access data in database management systems (DBMS) using SQL as a standard for accessing the data. ODBC permits maximum interoperability, which means a single application can access different DBMS.

Should I use ODBC or JDBC?

We can use ODBC for any language like C,C++,Java etc. We can use JDBC only for Java languages. JDBC Stands for java database connectivity. For Java applications it is not recommended to use ODBC because performance will be down due to internal conversion and applications will become platform Dependent.

Is ODBC faster than JDBC?

As you can see, with less number of records being fetched from the database, C(ODBC) performed better. But as the number of records were increased, Java(JDBC) came out as the winner.
