I have been collecting data using LabVIEW DSC 7.0 for several years and have always accessed the data from the Citadel database via the Historical Data Viewer. I would now like to begin putting this data into an Oracle database. My company stores all their data in Oracle and it would provide me all the benefits of their existing infrastructure such as automated backups, data mining tools, etc.
My initial thought is to use "Read Trace.vi" in LabVIEW to pull historical data from the citadel database at regular intervals (e.g. 1 minute) and insert this data into Oracle via ODBC. In this way, I do not need to track the value changes in order to know when to write to Oracle. I also considered replicating the citadel database using some other method, but I recall that the tables used by citadel are somewhat complicated. I only need a simple table with columns for channel, timestamp, and data. The "Read Trace.vi" will provide me data in this format.
I do not need to update the Oracle database in real time, a few minute delay is acceptable. If anyone has a better idea or additional insight please let me know. Thanks.
