ODBC Repository link Function library

There are 25 functions Open data links (Open Database connectivity, ODBC) in this library that are common interfaces for linking repositories. ODBC is the Microsoft-led database connectivity Standard, and the implementation environment is the most mature in Microsoft's system.

In Unix systems, it is common to use ODBC interfaces provided by other vendors, and some UNIX vendors provide their own ODBC interfaces (such as SUN has ODBC for Solaris).
ODBC and database queries take the SQL language, which is the same as most database queries, making it easy to communicate with a variety of repositories. Of course, through the ODBC interface, the backend database does not necessarily have to be a DBMS for this large database system, it can be a table (such as Microsoft Access), or a spreadsheet (such as Microsoft Excel).
