performance - Why is ODBC slow? -

Why is the ODBC slow? What is the underlying architecture? Anyone can put more light on the same> Normally (and I usually have a general meaning) Add another layer in the ODBC driver mix, it needs to take your query and translate it into the original query language (where the original language is SQL Or its full implementation). That translation / interpretation adds a performance overhead which is worse for some data sources than others.
