Longhorn and WinFS

Microsoft's next major release of Windows, codenamed Longhorn, will come

packaged with a number of new technologies that you must make sure you

know about.

One of the new technologies being release with Longhorn is a new file

system called WinFS. WinFS is built upon NTFS and therefore has many of

the same security features of NTFS. However, WinFS is more like NTFS on

steroids because of the number of new capabilities that are now

available using WinFS.

WinFS is the active storage subsystem in "Longhorn" that is used for

searching, organizing, and sharing data. "WinFS" maintains a store of

items and their properties, and provides a system service in "Longhorn"

to retrieve information when it is needed.

WinFS is built upon the new SQL Server engine (codenamed Yukon) and is

the store for all types of data, whether structured, semi-structured, or

unstructured. For example, WinFS stores metadata information such as

author, title, date, etc. All of these attributes (or metadata) are now

easily searchable using WinFS. WinFS also defines the schemas for

contacts and calendar items.

Though the new capabilities of WinFS make Longhorn appealing to the

common user, the security features of NTFS will appeal to administrators

as well.

Join me next week when we discuss Longhorn's new display model,

codenamed Avalon.
