Windows Open Service Architecture
<architecture, library, microsoft> (WOSA) One of the mainstays of
Microsoft Windows: the ethos of abstraction of core services.
For each extension, Windows Open Services Architecture defines an API and an
SPI, as well as a universal interface (usually placed in a single DLL) that both
comply to.
These then transparently let the operating system speak to device drivers,
database managers, and other low level entities.
These extensions include, among others, ODBC (called the "crowning jewel of
WOSA"), TAPI, WOSA/XFS, SAPI and MAPI, and their supporting services, as well as
the abstraction of access to printers, modems, and networking services, which
run identically over TCP/IP, IPX/SPX, and NetBEUI.
