Record locking is also an important part of data security. If more than one person is accessing your database at the same time, it's possible that they'll try to change the same record at the same time. This can result in one set of information being lost. To prevent this, a record that one person is editing should be locked, so that anyone else using the same database is prevented from that record. Ideally, they should still be able to view the details, but not change them.
Data integrity is as important to a small organisation as it is to a large one.
The advent of the World Wide Web allowed organisations to reach people in all parts of the world easily and without the need to know where they were. It was quickly realised that what started as an academic tool could easily be turned into perhaps the world's best marketing machine. Setting up a Web site has become easy, with many competing service providers offering excellent packages, which include access provision and space for Web pages. Even small organisations can have a global presence without it costing the Earth. However, since that Web presence is just as affordable to your competition, you can't just leave it at that.
