converting MSAccess 97 db to Oracle 8i

hi all,
i have a Ms Access 97 database having 182 tables.i also have a license version of Oracle 8i personal edition.

problem :
i have an existing project in VB/Access and now for my new client who has his other systems in Oracle , i want to convert my existing MS ACCESS database to oracle and later use ODBC to connect to the Oracle db, connecting is not a problem but conversion is something really new for me.

firstly i dont know if i need to use import/export and if any one is to be used , how???????
is it easier to export from access or import from oracle???

how do i do that.i have installed ORACLE 8i personal edition for win 98 and have my access database ready .

this is very urgent so your kind attention is needed

regards
aniket bapat.
