You could create a table that is filled up in a process in the client
application login, so the user will define the company data they want to
see, you create a record on the session_table, the make views reference
this table, or you could have a column in the users table that is updated
every time the user choose a company to look for data, the make views that
links to the user table and have a where clause that looks like this:

Select * from atable join user on (user.companyid = atable.companyid) and
user.login = USER

I think this kind of approach could work.
