If you're modeling relational data, it doesn't seem like you can get around using a DB that uses SQL, which to me is the worst: most programmers aren't DB experts and the SQL they output is quite often terrible.
Not to dunk on the lemmy devs, they do a good job, but they themselves know that their SQL is bad. Luckily there are community members who stepped up and are doing a great job at fixing the numerous performance issues and tuning the DB settings, but not everybody has that kind of support, nor time.
Also, the translation step from binary (program) -> text (SQL) -> binary (server), just feels quite wrong. For HTML and CSS, it's fine, but for SQL, where injection is still in the top 10 security risks, is there something better?
Yes, there are ORMs, but some languages don't have them (rust has diesel for example, which still requires you to write SQL) and it would be great to "just" have a DB with a binary protocol that makes it unnecessary to write an ORM.
Does such a thing exist? Is there something better than SQL out there?
There are other query languages. InfluxDB develops one called Flux. It's a master class on why corporate led open source can really suck. Daily use features get deprecated all the time and each new release is breaking. The documentation is horribly insufficient and the language syntax is usually not clear and it wraps many behaviors into one vague function name. Yes, SQL is pretty impressive.
With Influx 3 the preferred language is gonna be their SQL dialect. Flux is on its way out and I suspect it will get deprecated in the near future. Flux saw very slow adoption and SQL can do everything as well.
