In Jet versions before version 4, a page locking model is used, and in Jet 4, a record locking model is employed. Microsoft databases are organized into data "pages", which are fixed-length (2 kB before Jet 4, 4 kB in Jet 4) data structures. Data is stored in "records" of variable length that may take up less or more than one page.
The Microsoft OLE DB Provider for ODBC, or MSDASQL, was an OLE DB provider for allowing ActiveX Data Objects access to databases via any ODBC driver. Microsoft supplied several OLE-DB providers (for the Indexing Service, Active Directory , Jet, SQL Server, Oracle ( MSDAORA [ 28 ] ) and Internet Publishing), however unless otherwise directed ...
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft that allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE .

JET Red before version 4.0 supports only page-level locking, while ESE and JET Red version 4.0 supports record-level locking. JET Red supports a wide variety of query interfaces, including ODBC and OLE DB. ESE does not ship with a query engine but instead relies on applications to write their own queries as C ISAM code. JET Red has a maximum ...
DAO were originally called "VT Objects.: DAO 1.0 came up in November 1992 as part of Access 1.0. In version 3.5 it was able to bypass the Jet engine all together and directly access ODBC data sources, including Microsoft SQL Server and other enterprise database systems. DAO 3.6 shipped with Jet 4.0.
During this time, Microsoft was in the midst of developing their Jet database system. Jet combined three primary subsystems; an ISAM -based database engine (also named Jet , confusingly), a C-based interface allowing applications to access that data, and a selection of driver dynamic-link libraries (DLL) that allowed the same C interface to ...
During the beta testing phase of Windows 2000, it included a feature titled Native Structured Storage (NSS) for storage of Structured Storage documents (like the binary Microsoft Office formats and the thumbs.db file Windows Explorer uses to cache thumbnails) with each Stream that makes up a document stored in a separate NTFS data stream. It ...
