I have a lot of CSV files which contain up to 20 columns with float numbers. Right now I am keeping these files in a folder. Every files is related to specific user and specific date. Files usually are not bigger than 5Mb.
Which SQL/NoSQL Engine should I use for storing this data? Also, is it better to just store CSV files inside DB or maybe should I somehow transfer data and save as document?
I am using C# and I need serverless DB so that I dont need to install one. Right now I am considering LiteDB and RaportDB
