Before you install the toolkits, you would have to buy them.

The LabVIEW toolkit can be ordered
here. The older toolkits for database connectivity were actually included with TestStand 2.0 which was kind of nice but I prefered the TestStand steps. The toolkits (LabVIEW's, anyway) makes database work nice and simple and is based on ADO, just like the TestStand steps. If you want lower level functions, the free
LabSQL is available and is also based on ADO. SQL is a common database language and you would need some familiarity with it to use LabSQL. The queries that are issued by the TestStand step types are SQL language queries and the toolkits issue these as well but the higher level functions hide some of this from you.
