There's one exception to the equivalence of SQL on the one hand to XML or JSON on the other hand. The point of SQL (and other DBMS paradigms) is to give access to data that's orders of magnitude bigger than the RAM in which the app runs. That has stayed true for at least a quarter century, during which RAM and database sizes both did the Moores-law exponential expansion.
- fjfaase 5y agoA relational database maps everything to unordered relationships. Representing or manipulating a tree like structure is complex. Just representing an ordered list is complex. In XML and JSON everything is ordered and querying it as relational database is cumbersum. Graph databases and OO databases are somewhere in the middle. But as I wanted to point out, which data models are used, is not the major obstacle to the semantic web. It is these other problems that are not addressed.
