I manage a research group and need to track, for all manuscripts I am going to submit soon, things like funding agency I need to add for that manuscript, authors for the other, potential journals for submission, etc, etc. Currently I build an excel sheet but things are getting very complicated due to all details I need to add, and wonder whether you have the same problem and which solution did you find, if you can share it, or if you use any other software for this.
Well, there might be a middle ground between spreadsheets and relational DBs. A couple years ago I signed up as a trial user for a tech startup called Fieldbook, which aimed at making data storage and manipulation in RDBs simpler and more intuitive.
Admittedly, I didn't have the time or need to play around too much so I don't know if it's good enough for your use case (for that matter you haven't really given any detail specs) but give it a go if you like (I believe they have a free trial).
The advantage here that it appears to be easily scalable and always available through online access, so no other software besides a web browser is necessary.
