Lock a Vertex Database

The operating system's locking features are used to lock the database. The database locking feature is related to the d_DATABASEl file.

In practice, a database can be used by more than one user at a time. When saving the database, the program will check whether the users have been editing the same database row.

If the same database is being edited by several users who are editing the same database row, the program will save the changes made by the first user to save them. The other users will not be able to save the changes made to the same database row. Vertex will notify the user that another user has made changes to the same rows. Upon receiving this notification, the user can undo the changes made by pressing Ctrl+C.

If you make changes to more than one database row, you can make intermediate saves using the Ctrl+U function. This way, you are likely to avoid a situation where several users have opened the same database rows and their changes cannot be saved.
