The sentence irritates me a bit. Aren't almost all blockchains based on an SQL or relational database?
With a blockchain that runs on a SQL database, we can easily support applications utilizing the chain, or a separate 'asset chain' that is launched by any person/group wishing to, with its own set of 'rules' goverened by the 'groups' system on the chain.

Sure, but other Crypto has a rigid structure. You can Parse the data for BTC into an open source SQL but it will only reflect what each static block represents. That is a limitation utilizing the foundation of any crypto built this way, as a clone is stuck with the parameters of the way it stores its data.
Qortal is not a Clone of anything, not even Qora. Qortal is built from scratch by a CAT with some very sharp claws!
The database for Qortal is SQL and open to all applications to utilize. So you have a base that embeds the Crypto portion and a hash link to an open structure to build on top of for any application to be made. Qortal states this is Phase 3, but the framework is there inside HSQLDB. The devs had it up to 7Million rows as a test but lowered it due to blockchain size. Although, this means that an App may utilize this function locally and store data off chain but link to a hash on chain to verify and secure the data.
If your website is stored locally and references hash on the chain it can not be hacked to change any App that you serve. Couple this with encryption and the database you serve locally is also secure. Unhackable content! The framework would be an App that is downloaded so only TX needs to be sent and no personal data goes across the internet to top it off. Host stores locally and client stores locally TX back and forth on Chain.
