  1. WIN FS By Anthony Rocchio rjgk@iup.edu Information Assurance Group 20 September 2005

  2. Topics • What WinFS is • How WinFS works

  3. What WinFS is • 3 tenets of WinFS: • Find • Relate • Act

  4. 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

  5. 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

  6. 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.

  7. How WinFS works

  8. 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

  9. 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

  10. How WinFS works • APIs • Program the different building blocks of the WinFS system including data operations, rules, synchronization, and the data model.

  11. 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.

  12. 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.

  13. 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.
