ODBC database storage format and schemas
Use the ODBC database format to store data using an ODBC data source such as Oracle,
Microsoft SQL Server, or Microsoft Access.
The ODBC format stores data in up to three tables:
 Float table stores analog and digital tag values.
 String table (optional) stores string tag values.
When creating the tables for Float and String data logging to MS SQL Server 2008, ensure that
Microsoft SQL Server 2008 Service Pack 1 has been installed first, or table creation will not be
possible.
