Expected Qualities of a Modern Data Access Layer backed by an RDBMS (Personal Opinion)
View README.md
  1. High-Level and Accessible: Data should be made available via an API which doesn't require any (1) proprietary, idiosyncratic access technology, (2) custom query language, (3) a particular language, or (4) a particular run-time environment. In other words, users should be able to issue queries using a query language, over a communication protocol and on a run-time environment which they already are familiar with and be able to possess and maintain comfortably on a personal computer with minimal effort and no extra costs.
  2. Liberal: Consumers should be able to issue read/write queries
