Labview as a programming language can be used to communicate with a database, to add new recordsets to a database, to fetch values from a database.
There are several options you could use as the database core. E.g. some "open source", free databases as mysql, postgres, msde (ms "free" sql server) or you could interact with bigger databases from Oracle, DB2, MS SQLServer or probably even SAP.
The key point to this is how you communicate with the database, and there you could easily use the
LabVIEW Database Connectivity Toolkit on a Windows platform.
What type of application would you like to write? Maybe other add-on modules to LabVIEW helps you further to implement in an easy way your applic
ation.
e.g.
LabVIEW for Datalogging and Supervisory Control
NI DIAdemConfiguration-Based Datalogger - NI VI LoggerIf you are low on budget, you might get some help from this link:
LabVIEW Open Source Tools (L.O.S.T.) - LabSQLHope this helps
