What is the CALL Interface and what is it used for?
In addition to the precompilers, ADABAS provides a CALL Interface to allow SQL applications to be written in programming languages other than C/C++ or COBOL. Some application programmers prefer an SQL-API to a precompiler concept. The SQL-API supported by ADABAS conforms to that of Microsoft ODBC, the only industrial standard in this field. Thus an ODBC-compatible interface is also made available on UNIX systems, for example.
