Database design to manage data from Serial Port? -
i'm writing codes capture serial port data (e.g. micrometer) , following
- real time display , graphing
- delete/modify/replace existing data focus , re-measurement,
- save data somewhere additional statistical analysis (e.g. in excel). out put .csv option
because each measurement may capture hundreds thousands of data (measurement points), i'm not sure how shall go design database - shall create new row each data received, or shall push data array , store super long string separated comma database? such application, need server 2008 or server 2008 express sufficient. pros/cons in terms of performance?
is possible create such application client won't need install sql server?
to answer last question first, @ sqlite because free open source, , i'm pretty sure license null. plus nothing install users. sqlite can compiled code.
to answer primary question, encourage using database if makes sense. going running queries against data, or looking store , retrieve entries sort of identifier? discourage storing super long comma separated string, instead blob type. blobs, can put datatypes database can them out, plus believe more efficient way. suggest using text type if need sort of text query on it. example fulltext searches
