WinFS (short for Windows Future Storage) was the for a canceled data storage and system project based on, developed by and first demonstrated in 2003 as an advanced storage subsystem for the, designed for and management of, and. WinFS includes a for storage of information, and allows any type of information to be stored in it, provided there is a well defined for the type.
Individual data items could then be related together by relationships, which are either inferred by the system based on certain attributes or explicitly stated by the user. As the data has a well defined schema, any application can reuse the data; and using the relationships, related data can be effectively organized as well as retrieved. Because the system knows the structure and intent of the information, it can be used to make complex queries that enable advanced searching through the data and aggregating various data items by exploiting the relationships between them. A mockup calendar application sorting images by the dates and using their relationship with contacts to filter the images. WinFS aimed at providing a shared system that would enable such a scenario. While WinFS and its shared type schema make it possible for an application to recognize the different data types, the application still has to be coded to render the different data types. Consequently, it would not allow development of a single application that can view or edit all data types; rather, what WinFS enables applications to do is understand the structure of all data and extract the information that they can use further.
When WinFS was introduced at the 2003, Microsoft also released a video presentation, named IWish, showing mockup interfaces that showed how applications would expose interfaces that take advantage of a unified type system. The concepts shown in the video ranged from applications using the relationships of items to dynamically offer filtering options to applications grouping multiple related data types and rendering them in a unified presentation. WinFS was billed as one of the pillars of the wave of technologies, and would ship as part of the next version of Windows. It was subsequently decided that WinFS would ship after the release of, but those plans were shelved in June 2006, with some of its component technologies being integrated into and.
Timeline of the various structured storage projects. None yet has resulted in a full featured runtime and API around it. Years are approximate.
The development of WinFS is an extension to a feature which was initially planned in the early 1990s. Dubbed Object File System, it was supposed to be included as part of. OFS was supposed to have powerful data aggregation features, but the Cairo project was shelved, and with it OFS. However, later during the development of, a storage system, called Storage+, based on then-upcoming SQL Server 8.0, was planned, which was slated to offer similar aggregation features. This, too, never materialized, and a similar technology, Relational File System (RFS), was conceived to be launched with SQL Server 2000.
However, SQL Server 2000 ended up being a minor upgrade to SQL Server 7.0 and RFS was not implemented. But the concept was not scrapped. It just morphed into WinFS. WinFS was initially planned for inclusion in, and build 4051 of Windows Vista, then called by its codename 'Longhorn', given to developers at the Microsoft in 2003, included WinFS, but it suffered from significant performance issues.
In August 2004, Microsoft announced that WinFS would not ship with Windows Vista; it would instead be available as a downloadable update after Vista's release. On August 29, 2005, Microsoft quietly made Beta 1 of WinFS available to MSDN subscribers. It worked on, and required the to run. The WinFS API was included in the System.Storage namespace. The beta was refreshed on December 1, 2005 to be compatible with version 2.0 of the.NET Framework. WinFS Beta 2 was planned for some time later in 2006, and was supposed to include integration with, so that search results include results from both regular files and WinFS stores, as well as allow access of WinFS data using.
On June 23, 2006, the WinFS team at Microsoft announced that WinFS would no longer be delivered as a separate product, and some components would be brought under the umbrella of other technologies. Examples of uses of the technology are the components into; support for unstructured data, adminless mode of operation, support for objects via the FILESTREAM data type, and hierarchical data in, then codenamed Katmai, as well as integration with and and support for traversal of hierarchies by traversing relationships into later releases of; and the synchronization components into. In 2013 Bill Gates cited WinFS as his greatest disappointment at Microsoft and that the idea of WinFS was ahead of its time, which will re-emerge.
Data storage Architecture. Architecture of the WinFS Stack WinFS uses a relational engine, which derives from SQL Server 2005, to provide the data-relations mechanism. WinFS stores are simply SQL Server database (.MDF) files with the FILESTREAM attribute set. These files are stored in the access-restricted folder named 'System Volume Information' (placed in the volume root), in folders under the folder 'WinFS' with names of of these stores. At the bottom of the WinFS stack lies WinFS Core which interacts with the and provides file-access and -addressing capabilities. The relational engine leverages the WinFS core services to present a structured store and other services such as which the WinFS runtime uses to implement the functionality. The WinFS runtime exposes services such as Synchronization and Rules which can be used to synchronize WinFS stores or perform certain actions on the occurrence of certain events.
WinFS runs as a which runs three:. WinFS.exe, which hosts relational datastore. WinFSSearch.exe, which hosts the indexing and querying engine.
WinFPM.exe (WinFS File Promotion Manager), which interfaces with the underlying file-system It allows programmatic access to its features via a set of. Accurate accounting enterprise 4 full keygen. These enable applications to define custom-made data types, define relationships among data, store and retrieve information, and allow advanced searches. The applications can then aggregate the data and present the aggregated data to the user. Data store WinFS stores data in relational stores, which are exposed as virtual locations called stores.
A WinFS store is a common repository where any application can store data along with its metadata, relationships and schema. WinFS runtime can apply certain relationships itself; for example, if the values of the subject property of a picture and the name property of a contact are same, then WinFS can relate the contact with the picture. Relations can also be specified by other applications or the user. WinFS provides unified storage, but stops short of defining the format that is to be stored in the data stores. Instead it supports writing data in application-specific formats.
But applications must provide a that defines how the file format should be interpreted. For example, a schema could be added to allow WinFS to understand how to read and thus be able to search and analyze, (say) a file. By using the schema, any application can read data from any other application, and this also allows different applications to write in each other's format by sharing the schema. Multiple WinFS stores can be created on a single machine. This allows different classes of data to be kept segregated; for example, official documents and personal documents can be kept in different stores. WinFS, by default, provides only one store, named 'DefaultStore'. WinFS stores are exposed as shell objects, akin to, which dynamically generate a list of all items present in the store and present them in a folder view.
The shell object also allows searching information in the datastore. A data unit that has to be stored in a WinFS store is called a WinFS Item. A WinFS item, along with the core data item, also contains information on how the data item is related to other data. This Relationship is stored in terms of logical links. Links specify which other data items the current item is related with.
Put in other words, links specify the relationship of the data with other data items. Links are physically stored using a link identifier, which specifies the name and intent of the relationship, such as type of or consists of. The link identifier is stored as an attribute of the data item.
All the objects which have the same link ID are considered to be related. An, defining the structure of the data items that will be stored in WinFS, must be supplied to the WinFS runtime beforehand. In Beta 1 of WinFS, the schema assembly had to be added to the GAC before it could be used. Data model WinFS models data using the data items, along with their, extensions and rules governing its usage. WinFS needs to understand the type and structure of the data items, so that the information stored in the data item can be made available to any application that requests it. This is done by the use of schemas.
For every type of data item that is to be stored in WinFS, a corresponding schema needs to be provided to define the type, structure and associations of the data. These schemas are defined using. Predefined WinFS schemas include schemas for documents, e-mail, appointments, tasks, media, audio, video, and also includes system schemas that include configuration, programs, and other system-related data. Custom schemas can be defined on a per-application basis, in situations where an application wants to store its data in WinFS, but not share the structure of that data with other applications, or they can be made available across the system.
Type system. WinFS Type Hierarchy The most important difference between a file system and WinFS is that WinFS knows the type of each data item that it stores. And the type specifies the properties of the data item. The WinFS type system is closely associated with the.NET framework’s concept of. A new type can be created by and nesting any predefined types. WinFS provides four predefined base types – Items, Relationships, ScalarTypes and NestedTypes.
An Item is the fundamental data object which can be stored, and a Relationship is the relation or link between two data items. Since all WinFS items must have a type, the type of item stored defines its properties. The properties of an Item may be a ScalarType, which defines the smallest unit of information a property can have, or a NestedType, which is a collection of more than one ScalarTypes and/or NestedTypes. All WinFS types are made available as.NET CLR. Any object represented as a data unit, such as contact, image, video, document etc., can be stored in a WinFS store as a specialization of the Item type. By default, WinFS provides Item types for Files, Contact, Documents, Pictures, Audio, Video, Calendar, and Messages.
The File Item can store any generic data, which is stored in file systems as files. But unless an advanced schema is provided for the file, by defining it to be a specialized Item, WinFS will not be able to access its data. Such a file Item can only support being related to other Items. Defining a new Type A developer can extend any of these types, or the base type Item, to provide a type for his custom data. The data contained in an Item is defined in terms of properties, or fields which hold the actual data.
For example, an Item Contact may have a field Name which is a ScalarType, and one field Address, a NestedType, which is further composed of two ScalarTypes. To define this type, the base class Item is extended and the necessary fields are added to the class.
A NestedType field can be defined as another class which contains the two ScalarType fields. Once the type is defined, a schema has to be defined, which denotes the primitive type of each field, for example, the Name field is a String, the Address field is a custom defined Address class, both the fields of which are Strings. Other primitive types that WinFS supports are, and DateTime, among others. The schema will also define which fields are mandatory and which are optional. The Contact Item defined in this way will be used to store information regarding the Contact, by populating the properties field and storing it. Only those fields marked as mandatory needs to be filled up during initial save.
Other fields may be populated later by the user, or not populated at all. If more properties fields, such as last conversed date, need to be added, this type can be extended to accommodate them.
Item types for other data can be defined similarly. Relationships WinFS creates for all defined Items. All the fields defined for the Item form the columns of the table and all instances of the Item are stored as rows in the table for the respective Items.
Whenever some field in the table refers to data in some other table, it is considered a relationship. The schema of the relationship specifies which tables are involved and what the kind and name of the relationship is. The WinFS runtime manages the relationship schemas. All Items are exposed as.NET CLR, with a uniform interface providing access to the data stored in the fields. Thus any application can retrieve object of any Item type and can use the data in the object, without being aware of the physical structure the data was stored in. WinFS types are exposed as.NET classes, which can be instantiated as.NET objects.
Data are stored in these type instances by setting their properties. Once done, they are persisted into the WinFS store. A WinFS store is accessed using an ItemContext class (see section for details).
ItemContext allows transactional access to the WinFS store; i.e. All the operations since binding an ItemContext object to a store till it is closed either all succeed or are all rolled back. As changes are made to the data, they are not written to the disc; rather they are written to an in-memory log. Only when the connection is closed are the changes written to the disc in a batch. This helps to optimize disc I/O. The following code snippet, written in, creates a contact and stores it in a WinFS store.
WinFS Relationships In WinFS, a Relationship is an instance of the base type Relationship, which is extended to signify a specialization of a relation. A Relationship is a mapping between two items, a Source and a Target.
The source has an Outgoing Relationship, whereas the target gets an Incoming Relationship. WinFS provides three types of primitive relationships – Holding Relationship, Reference Relationship and Embedding Relationship.
Any custom relationship between two data types are instances of these relationship types. Holding Relationships specifies ownership and lifetime (which defines how long the relationship is valid) of the Target Item. For example, the Relationship between a folder and a file, and between an Employee and his Salary record, is a Holding Relationship – the latter is to be removed when the former is removed. A Target Item can be a part of more than one Holding Relationships. In such a case, it is to be removed when all the Source Items are removed. Reference Relationships provide linkage between two Items, but do not have any lifetime associated, i.e., each Item will continue to be stored even without the other.
Embedding Relationships give order to the two Items which are linked by the Relationship, such as the Relationship between a Parent Item and a Child Item. Relationships between two Items can either be set programmatically by the application creating the data, or the user can use the WinFS Item Browser to manually relate the Items. A WinFS item browser can also graphically display the items and how they are related, to enable the user to know how their data are organized. Rules WinFS includes Rules, which are executed when a certain condition is met. WinFS rules work on data and data relationships.
For example, a rule can be created which states that whenever an Item is created which contains field 'Name' and if the value of that field is some particular name, a relationship should be created which relates the Item with some other Item. WinFS rules can also access any external application. For example, a rule can be built which launches a Notify application whenever a mail is received from a particular contact. WinFS rules can also be used to add new properties fields to existing data Items. WinFS rules are also exposed as.NET CLR objects. As such any rule can be used for any purpose.
A rule can even be extended by inheriting from it to form a new rule which consists of the condition and action of the parent rule plus something more. RAV WinFS supports creating Rich Application Views (RAV) by aggregating different data in a virtual table format. Unlike, where each individual element can only be a scalar value, RAVs can have complex Items or even collections of Items.
The actual data can be across multiple data types or instances and can even be retrieved by traversing relationships. RAVs are intrinsically paged (dividing the entire set of data into smaller pages containing disconnected subsets of the data) by the WinFS runtime. The page size is defined during creation of the view and the WinFS API exposes methods to iterate over the pages. RAVs also supports modification of the view according to different grouping parameters.
Views can also be queried against. Access control Even though all data are shared, everything is not equally accessible. WinFS uses the to provide two data protection mechanisms.
First, there is share-level security that controls access to your WinFS share. Second, there is item level security that supports NT compatible security descriptors. The process accessing the item must have enough privileges to access it.
Also in Vista there is the concept of 'integrity level' for an application. Higher integrity data cannot be accessed by a lower integrity process. Data retrieval. Flowchart for creating, searching and updating WinFS data instances The primary mode of data retrieval from a WinFS store is querying the WinFS store according to some criteria, which returns an set of items matching the criteria. The criteria for the query is specified using the. The returned data are made available as instances of the type schemas, conforming to the. The data in them can be accessed by accessing the properties of individual objects.
Relations are also exposed as properties. Each WinFS Item has two properties, named IncomingRelationships and OutgoingRelationships, which provides access to the set of relationship instances the item participates in. The other item which participates in one relationship instance can be reached through the proper relationship instance. The fact that the data can be accessed using its description, rather than location, can be used to provide end-user organizational capabilities without limiting to the hierarchical organization as used in file-systems.
In a file system, each file or folder is contained in only one folder. But WinFS Items can participate in any number of holding relationships, that too with any other items. As such, end users are not limited to only file/folder organization.
Rather, a contact can become a container for documents; a picture a container for contacts and so on. For legacy compatibility, WinFS includes a pseudo-type called Folder which is present only to participate in holding relationships and emulate file/folder organization. Since any WinFS Item can be related with more than one Folder item, from an end user perspective, an item can reside in multiple folders without duplicating the actual data.
Applications can also analyze the relationship to present various filters. For example, an email application can analyze the related contacts and the relationships of the contacts with restaurant bills and dynamically generate filters like 'Emails sent to people I had lunch with'. Searches The WinFS API provides a class called the ItemContext class, which is bound to a WinFS store. The ItemContext object can be used to scope the search to the entire store or a subset of it. It also provides access to the store.
An object of this class can then spawn an ItemSearcher object which then takes the type (an object representing the type) of the item to be retrieved or the relationship and the string representing the criteria for the search. A set of all matches is returned, which can then be bound to a UI widget for displaying en masse or enumerating individually.
The properties items can also be modified and then stored back to the data store to update the data. The ItemContext object is closed (which marks the end of association of the object with the store) when the queries are made or changes merged into the store. Related items can also be accessed through the items. The IncomingRelationships and OutgoingRelationships properties give access to all the set of relationship instances, typed to the name of the relationship. These relationship objects expose the other item via a property.
So, for example, if a picture is related to a picture, it can be accessed by traversing the relationship as. ContactsCollection contacts = picture. Cast ( typeof ( Contact )).
Value; //This retrieves the collection of all outgoing relationships from a picture object //and filters down the contacts reachable from them and retrieves its value. //Or the relationship can be statically specified as ContactsCollection contacts = picture. Contact; An OPath query string allows to express the parameters that will be queried for to be specified using properties, embedded Items as well as. It can specify a single search condition, such as 'title = Something', or a compound condition such as 'title = 'Title 1' title = 'Title 2' && author = 'Someone'. These boolean and relational operations can be specified using like &&, =,!= operators as well as their English-like equivalent like EQUAL, NOT EQUAL. Like operators such as LIKE, GROUP BY and ORDER BY are also supported, as are wildcard conditions.
So, 'title LIKE 'any.' is a valid query string. These operators can be used to execute complex searches such as. WinFS included StoreSpy, a WinFS Item browser that could be used to browse structured data instances with their properties and relationships.
With WinFS Beta 1, Microsoft included an unsupported application called StoreSpy, which allowed one to browse WinFS stores by presenting a hierarchical view of WinFS Items. It automatically generated based on access permissions, date and other metadata, and presented them in a hierarchical tree view, akin to what traditional folders are presented in. The application generated tabs for different Item types. StoreSpy allowed viewing Items, Relationships, MultiSet, Nested Elements, Extensions and other types in the store along with its full metadata. It also presented a search interface to perform manual searches, and save them as virtual folders. The application also presented a graphical view of WinFS Rules. However, it did not allow editing of Items or their properties, though it was slated for inclusion in a future release.
But the WinFS project was cut back before it could materialize. Type Browser WinFS also includes another application, named WinFS Type Browser, which can be used to browse the WinFS types, as well as visualize the hierarchical relationship between WinFS types. A WinFS type, both built-in types as well as custom schemas, can be visualized along with all the properties and methods that it supports. It also shows the types that it derives from as well as other types that extend the type schema. However, while it was included with WinFS, it was released as an unsupported tool. OPather WinFS Beta 1 also includes an unsupported application, named OPather. It presents a interface for writing queries.
It can be used by selecting target object type and specifying the parameters of the query. It also includes -like parameter completion feature. It can then be used to perform visualization tasks like binding results of a query to a control, create views of the data in WinFS itself, or just extract the query string. Project 'Orange' Microsoft launched a project to build a data visualization application for WinFS. It was codenamed 'Project Orange' and was supposedly built using. It was supposed to provide exploration of Items stored in WinFS stores, and data relationships were supposed to be a prominent part of the navigation model.
It was supposed to let people allow organization of the WinFS stores graphically as well – productizing many of the concepts shown in the. However, since the WinFS project went dark, the status of this project is unknown.
