With regard to the RDBMS APIs: The Rogue Wave DB Link API hides all the proprietary, RDBMS-specific API calls, as well as RDBMS-specific call sequencing. Using one single call, you can have your SQL statement executed.

With regard to platforms and compilers: Your code can be used to communicate with different RDBMSs simultaneously. As Rogue Wave DB Link is platform-independent, you do not have to rewrite any code when changing your platform or compiler. The Rogue Wave DB Link API is similar to the Call Level Interface (CLI) ISO standard but adapted to the C++ language.

With regard to the contents of the SQL statements: Usually, Rogue Wave DB Link does not change the contents of the SQL statements you send to the RDBMS. The only exception is for MS SQL Server, which does not support placeholders. The Rogue Wave DB Link Library interface lacks the necessary functionality. In fact, most of the time, Rogue Wave DB Link does not even read the SQL statements you send. This allows you to send any query you want, but it also means that Rogue Wave DB Link does not check whether your SQL code complies with a standard such as SQL92 or the SQL implementation specific to a given RDBMS.

If the target RDBMSs are known from the beginning, the application can be linked with the appropriate drivers.

If the application does not specify one or more target RDBMSs, it can be linked with the Rogue Wave DB Link driver manager, which will dynamically load the appropriate drivers when necessary.
