parse.com because of the multiple API support. You can get to your data from many platforms such as IOS, Android etc. I added to these lately with parse.com - nosql database for VBA and parse.com - noSQL database for GAS, giving a way to use parse.com to share data between its existing supported platforms, VBA and Google Apps Script.I like scriptDB, but in many ways I prefer to use
The parse API works well, so why not make one for ScriptDB that could be accessed initially by VBA, but later by other platforms too. I've poked around with this in a few examples such as Locking down scriptDB, Using data from multiple scriptDB, Hosting your public scriptdb and many others, but I thought it was about time to do a full blown one that allows updating and so on as well as querying. As a design criteria, I wanted to keep the interface as close to the parse.com ones as possible. Like this, the main code could remain the same, with just the API library differing depending on the underlying database chosen.
You can get cDataSet.xlsm to test all this from Downloads.
You can get me on Google plus, Twitter or this forum, and compare this topic with parse.com - nosql database for VBA and parse.com - noSQL database for GAS so you can see more about choosing about which noSQL database to use.
