optimistic concurrency

OLE DB

A database architecture that provides universal data integration over an enterprise's network, from mainframe to desktop, regardless of the data type. OLE DB is a more generalized and more efficient strategy for data access than ODBC, because it allows access to more types of data and is based on the Component Object Model (COM).

optimistic concurrency

A type of locking in which the data page or row containing one or more records (rows) — (including the data being edited) — is unavailable to other users only while the data is being updated, but is available between the Edit and Update operations.
