You should be careful if you consider ODBC, its usage makes sense if
you want to have an application layer able to work with multiple
database systems as its routines are the same for all ODBC drivers,
say Oracle, MSSQL, Postgres and DB2. So using it can simplify your
life, and also complicate it as each database system has its
properties, SQL grammar, session tweaks, etc.
