• all database connection settings are under micro-ice-db key in config file
• db connection can be configured by version under version key (ex: v1)

• driver required Mysqli, Sqlsrv, Pdo_Sqlite, Pdo_Mysql, Pdo(= Other PDO Driver)
• database generally required the name of the database (schema)
• username generally required the connection username
• password generally required the connection password
• hostname not generally required the IP address or hostname to connect to
• port not generally required the port to connect to (if applicable)
• charset not generally required the character set to use

Other names will work as well. Effectively, if the PHP manual uses a particular naming, this naming will be supported by the associated driver. For example, dbname in most cases will also work for 'database'. Another example is that in the case of Sqlsrv, UID will work in place of username.
