DBF File Format - Considerations A Secure Option

... friends,

The DBF file format is a stable, reliable, and widely used option for data storage and management.
In a multi-user environment, the probability of concurrent access is relatively low, and the wait times in the event of collisions are minimal.
Therefore, the DBF format represents a good ...

TData is a class derived from TDatabase. So, in all probability, this should work with TData also.

In some cases, the functionality of TData may be different from TDatabase. That is where Mr. James Bott has ...

The right way is to config your router first. You should modify its DHCP server to reserve some addresses for fixed IPs.
