I am collecting data (alarm & counter) from several serial devices which have memory and RTC. Therefore I have to take into account that the collected data will not be chronological and I may need to sum newly collected data to existing records and then overwrite the record. It is possible to reach about 50,000 records/month. In addition, I need to add the data together and graph hourly, daily, weekly, monthly, etc. So read speed is very important for user interaction.
Can someone recommend the best file type or data management practice for this? I am using LV 8.5, so would like to use TDMS but cannot overwrite records in this version. Currently I've settled on MGI Read/Write Anything, but is this the best solution? I'd like to avoid DB Connectivity Toolkit and don't think I'd get any speed advantage anyway. I just need the best way to pull out an individual record, overwrite it, and scan quickly through the entire file.
Are there any other tools in later LV versions other than overwriting TDMS records?
