So far I haven't noticed much (any?) support for key-value (e.g. BerkeleyDB) and "NoSQL" relational database (like MongoDB) based systems.
The latter especially seem they would fit quite nicely into the FPC/Lazarus database classes (like TDataset), which would be very usable for "fat clients" which are easily constructed in Lazarus. The former ones are a great idea for embedded data storage for applications, and simpler to use than say, SQLite.
Has anyone started some work on that? Are there at least Pascal bindings available for the above quoted DBMS's?
