It's a "must" only internally providing the column-store core functinality to high-level data model & query language front-ends, like, e.g., the SQL frontend. Externally, MonetDB/SQL (obviously) provides standard SQL. > > 4. .mx files > In MonetDB, .mx files are compiled to make .h and .c files generated.(in > this way ?) > Why is this routines ? (not just coding in .h and .c files directly) To facilitate literal programming and code expansion.
