this is possible even if they are in same database. alll relational databases, sql server/oracle supports this. create separate tablespaces and let the tablespaces be in separate files in separate disks... & then create the tables in separate tablespaces...

yes you can,.. trigger is a plsql block and u can call procs / funcs in it.

there could be... provided the database is hosted on raid and the tables are located in diffetent physical files.

just store the previos value in some temporary variable and set all to the text box at once. or at the time when you are setting value at the text box consider existing value also eg

text1.text += text1.text + "a"
