Hi γείτονας! I live in Edirne!
I read your brief. Its possible to use data from MS Access db, but we cannot use the existing forms, so have to be converted to HTML first.
I've done similar jobs before. If your dataset is not huge (under 500MB, for example) I can export data to Sqlite db, if bigger, to Mysql. Then use PHP to make you an online app, almost identical to your MS Access DB, with all, or maybe better functionality if you want.
Just feel free to contact me for details.
Best regards,
Baris
