You can log shared variable data, alarms, and events to the following supported relational databases: Microsoft Access, MySQL, Oracle, PostgreSQL, and SQL Server. Logging data to a supported relational database enables you to work with shared variables, alarms, and events in a database other than the Citadel database. You must be familiar working with the supported relational database before logging data to that database.
You can log to a supported relational database by using one of the following methods:
|Note The default database is located in the C:\ProgramData\National Instruments\Tagger\nivariable_database directory.|
|Note You also must enable logging for shared variables.|
Use the Table Management dialog box to specify the table name for each data type that logs to the database. The DSC Module supports logging the following data types to a supported relational database: numeric, Boolean, and string. Each data type logs to a separate table. LabVIEW also logs alarms and events to a separate table. You can customize the table name for each data type that LabVIEW logs by process. For example, you can specify that data of the same data type from different processes logs to the same table or to different tables.
