You should be able to connect flash with any database, you need some kind of server side scripting language to link between the database and flash (mySQL is commonly used with PHP a with a microsoft databse you're likely to use ASP) the process works by flash sending variables from the movie to an ASP script, this ASP script can maybe do some kind of processing and then insert data into the db. To retrieve data again you use the loadVariables action to call an ASP script this script can query the database to find the desired information and then send the variables to flash where they can be displayed.
