Programming for Shared Access

If you create an application that will run on several machines in a network environment or if several instances of a form will access the same data, then you must program for shared access. Shared access means providing efficient ways of using and sharing data among users, as well as restricting access when necessary.

Microsoft Visual FoxPro provides support for shared or exclusive access to data, locking options, data sessions, record and table buffering, and transactions. Although these features are useful particularly in shared environments, you can use them in single-user environments too.
