Database System

Information on DB.dll
DB.dll is an ODK component for accessing databases via C API functions. The functionality
is no longer supported for use with WinCC. Do not develop new applications with the database
access layer DB.dll from WinCC.
Instead, use the following functions offered by Microsoft:
● Use ADO.NET for .NET-based applications. The database interface of .NET Framework is
object-oriented and designed for scalable applications. The interface is also well suited for
data communication through firewalls.
● You can use OLE DB for C++ based applications. Microsoft provides templates with Visual
Studio for this. They make it easier to use the OLE DB database technology with classes,
which implements many commonly used OLE DB interfaces.
● You can also use ODBC C++ based applications. Microsoft provides classes for this, which
facilitate programming.
You can find more detailed information and examples on the Microsoft website.
