So why not let Visual FoxPro manipulate remote data directly, just as if you w

However, the speed of DML (insert, update, and delete) operations will be significantly slowed down because more indexes must be maintained for each operation. Therefore, if your query mainly contains select statements, it is very helpful to use more indexes. If your applicationProgramTo perform many DML operations, it is necessary to control the number of created indexes.
