When the DATABASE= option is specified for an Access database.mdb file that does not exist, a database is created using the format specified in the DBMS= option. If, however, you’re building a web app, and can only afford a single database (no multi-modelling), a RDBMS such as MySQL will rarely be the wrong choice.
