A method for managing a binary object in a database system is provided. The method may include receiving a request to store the binary object and determining if a size of the binary object is above a first threshold. If the size is less than the first threshold, the method may include storing the binary object in a database of the database system using a database communication protocol. If the size is above the first threshold, the method may include determining if the size is above a second threshold. To this end, if the size is less than the second threshold, the method may include storing the binary object in a file system of the database system using the database communication protocol. Furthermore, if the size is above the second threshold, the method may include storing the binary object in the file system using a file system communication protocol.

Managing a binary object in a database system

Embodiments described herein are directed to the accessing remotely stored binary object data in a binary object store. In one embodiment, a computer system receives a request for a portion of binary object data, sends a query to a database server requesting access to the binary object data, and receives a binary object reference. The binary object reference includes binary object identification data and use characteristics specific to the binary object store. The computer system sends a binary object data access request based on the binary object reference to the binary object store using a binary object store interface, and receives the binary object data corresponding to the binary object data access request. The binary object data comprises a portion of data files. The computer system also sends the received binary object data to the user.

Remote storage and management of binary object data

An operating system is provided. The system includes an agent component to monitor computer activities between one or more single-item access components (SIAC) and one or more set-based access components (SBAC). An interface component is employed by the agent component to process kernel mode requests from a user mode application when communicating with a storage platform. Re-try components can be provided to facilitate cooperation between the SIAC and the SBAC.

User mode file system serialization and reliability

An operating system is provided. The system includes an agent component to monitor computer activities between one or more single-item access components and one or more set-based access components. A protocol component is employed by the agent component to mitigate data access between the single-item access components and the set-based access components.

Multi-protocol access to files and directories

The claimed subject matter provides a system and/or a method that extends transactional guarantees to unstructured data in a file system. A database engine, configured to retain structured data, can reserve a portion of the file system to store unstructured data to be managed by the database engine. A kernel component can associate a transaction with at least one stream that corresponds to the reserved portion of the file system. The association enables transaction based access to the reserved portion of the file system managed by the database engine.

Integration of unstructed data into a database

Systems and methods that create a virtual name space of Universal Naming Convention (UNC) over a local file system (e.g., drive letter based names), via employing a UNC provider and filter arrangement that changes a name in the file object to reparse it to a volume where the local file exists. A name in the file object is changed to a local name (e.g., morphed name); subsequently reparsed and forwarded to a Name Space Owner component (NSO). As such, a request can originate from a UNC stack and reparsed on the local stack. The name space is presented to an application in UNC format, while the underlying file write occur in the file system.

Virtual universal naming convention name space over local file system

An operating system is provided. The system includes an agent component to monitor computer activities between one or more single-item access components and one or more set-based access components. A protocol component is employed by the agent component to mitigate data access conflicts between the single-item access components and the set-based access components.

Systems and methodologies for integration of an anti virus AV Plug In(s) as part of an Item Store. The semantics for operation of the AV Plug In(s) are provided by the relational Item Store, via employing a metadata component and a scanning component associated with the Item Store. The metadata component can supply a signature value being associated with the Item Store that can represent the time of scanning of data, and outcome for every scanned item. The scanning component can provide for a queuing of items in the data store in a synchronous and/or asynchronous mode for both scanning and cleaning by the AV Plug In supplied by vendors.

Anti virus for an item store

The invention provides a distributed file system configured to delegate file system operations to clients. The client obtains a delegation associated with an object managed by the server. The delegation enables the client to perform a file system operation on behalf of the server. The client caches the object and enables users associated with the client to access the object in accordance with the delegation.

System and method for delegating file system operations

The invention provides a system and method for managing cached objects using notification bonds. A server is configured to manage original objects. A client creates cached objects from the original objects and establishes notification bonds with the server. Each notification bond enables the client to obtain a notification from the server in response to an object related event associated with an original object. The client uses the data in the notification to update the cache object corresponding to the original object without synchronizing other cache objects.

System and method for managing cached objects using notifications bonds

A file stream exchange system and method are provided. The system can be employed, for example, with a storage system that supports transactions as a primary mechanism and employs a rich type system. The system provides a mechanism for the storage system to provide reliable updates to file streams while preserving the common criteria for security. The system includes a replace stream component which is a kernel mode mechanism that allows transactional exchange of stream data of two file-backed items without violating the common criteria for security.

Mechanism to exchange primary data stream of a file

Access to WebDAV (Distributed Authoring and Versioning) servers is provided in a manner that is essentially transparent to applications. A WebDAV redirector and related components support file system I/O requests and network requests directed to WebDAV servers identified by URI (Universal Resource Identifier) names, or by a drive may be mapped to a WebDAV share. An application's create or open I/O requests directed to a WebDAV server are detected, and result in a local copy of the file being downloaded and cached for local access. When closed, the local file is uploaded to the WebDAV server. Network-related requests such as for browsing that are directed to a WebDAV server are also handled transparently. WebDAV files may be locally encrypted and decrypted at the file system level, transparent to applications and the WebDAV server, via an encrypting file system that performs local encryption and decryption at the local file system level.
