SUMMARY

Advanced: Requires expert coding, interoperability, and multiuser *skills.

Cluster indexing and row-level locking are not possible with Microsoft Access, unless you are using a linked (attached) table.

MORE INFORMATION

These features are not supported because of the variable-length architecture. When using a linked table, Microsoft Access uses the same locking scheme as the native product. When you use the installable ISAMs for dBASE, Paradox, and Btrieve, you do record- level locking. The Paradox ISAM even understands clustered indexes and takes advantage of these indexes in some queries.

NOTE: The Btrieve ISAM driver applies only to Microsoft Access 1.x and 2.0.
