1, if you need to write and update the database operation, and sometimes set the database Write permission!
2, when updating the database operation, it is best to lock the database, so that there are other people at the same time, there is a conflict.
3, for the sake of security, should set password access to the database, although the crack is relatively simple, but there is a layer of security permissions of course better than no better.
4, set up a directory for the database, and a special name for the data, as far as possible is not common, to prevent malicious users to guess the path and name of the database, directly download the database. You can also set the database to be in the form of an ASP file.
5. Use an Access database for simpler, less data-critical data, using SQL or Oracle databases as much as possible.
6, the important data and ordinary data and other data separate, do not place in the same database, so as to avoid the loss of important information.
Opinion, would you please discuss
