• What WinFS is
• How WinFS works
What WinFS is
• 3 tenets of WinFS:– Find
– Relate
– Act
What WinFS is
• Find:– 15 to 30 percent of time looking for information.
– Improve the speed and accuracy of finding information
– New types of data such as multimedia and new forms of communication and collaboration.
– Current file system does not know how to collect and find information within these new types of data
What WinFS is
• Relate:– Data relationships are built into the system, linking
together all the different types of data that people work with
– Graphically display these related items
– Users get a better understanding of how their data all fits together
What WinFS is
• Act:– Turn data into useful information that can be acted
upon.
– Remove tedious data activities that can be automated
– WinFS Rules are a built-in component of the system that allows you to tell the system how to work with, sort, and deliver data.
How WinFS works
How WinFS works
• Core WinFS– The fundamentals, which includes operations and
file system services
– Security, manageability, Win32 file access support, import/export, quotas…
• Data Model– Basic item structure and relationships
How WinFS works
• Schemas– Provide a more structured way to handle your data's
metadata.
• Services– “Sit on top" of WinFS to provide capabilities that
extend beyond the fundamentals of the system.
– Enable you to synchronize WinFS systems across a
network
How WinFS works
• APIs– Program the different building blocks of the WinFS
system including data operations, rules, synchronization, and the data model.
How WinFS works
• Direct Acyclic Graph of items (DAG). – Set of stored items and their relationships
– Physical storage is a relational database
– Possible to find items according to the value of their properties and even to the value of the properties of items related to them.
How WinFS works
• Everything that is stored is an item
• Each item has metadata properties that are described by a schema.
• T-SQL views give access to the items' properties.
How WinFS works
• Only applies to folders within the Documents and Settings folders.
• All other folders still reside under the control of NTFS.
• %systemroot% and Program Files are NTFS folders, – application executable files will not actually live in
the WinFS store.
