ODBC means open database connectivity

ODBC is the abbreviation for open database connectivity. ODBC is a standardised and universal database interface from Microsoft, which uses SQL as a database language. It provides access to data in a heterogeneous environment of relational and non-relational database management systems. ODBC is database independent, like SQL, but takes over functions that are not particular to SQL: for example, the user must first create a connection to the database.

ODBC is a universal database interface from Microsoft

Based on the call level interface specification of the SQL Access Group, ODBC provides an open and vendor-independent opportunity to access data which is stored in a number of personal computers, minicomputers and mainframe databases. ODBC offers many possibilities: with ODBC developers can simultaneously access an application, view the data and change it – from several different databases.

ODBC is a central component of the Microsoft Windows Open Services architecture. Apple has announced it will support ODBC as central technology in the future. This means that ODBC has received growing industry-wide support for data access via Windows and Macintosh.
