We had an interesting conversation about how the impedance mismatch between contemporary high-level programming languages (Java, C#, Python, VB) and relational databases. Since a huge percentage of code requires access to databases, the glue (a.k.a. the connecticazoint) between the RDBMS layer and the application code is very important, yet virtually every modern programming language assumes that RDBMS access is something that can be left to libraries. In other words, language designers never bother to put database integration features into their languages. As a tiny example of this, the syntax for "where" clauses is never identical to the syntax for "if" statements. And don't get me started about data type mismatches: just the fact that columns of any type might be "null" leads to an incompatibility between almost every native data type and the database data types.
