That's the problem, business systems are not complex, they are incredibly simple, they are made complex by the way we think about and structure our models and then interact with them. We have the wrong boundaries, and the wrong languages
Would you be able to point me towards modelling approaches/boundaries/languages that would be more appropriate? I'd be interested to learn about better alternatives, as I don't yet see the big flaws in relational models
Counter-intuitively Datomic is in violent agreement with /u/rqmedes where he said "A better alternative is having the data, data model and business logic tightly bound in one place. Not separated in multiple "tiers"" – Datomic inverts/unbundles the standard database architecture such that the cached database index values are distributed out and co-located with your application code such that database queries are amortized to local cost. Immutability in the database is how this is possible without sacrificing strong consistency, basically if git were a database you end up at Datomic.
Unfortunately there is no real alternatives, its like operating systems, one or two system have so much momentum that using anything else becomes extremely difficult even when they are inferior in certain domains. see http://www.fixup.fi/misc/usenix-login-2015/login_oct15_02_ka...
