Data Access and Storage

Windows has APIs, components, and services that support your desktop apps in data access and storage. They provide:

  • File and file system management.
  • Database access.
  • Support for the transfer, synchronization, and replication of data.
  • Access to XML, package, and log files.
  • Image mastering.
  • Backup support.

TopicDescription

Background Intelligent Transfer Service

Background Intelligent Transfer Service (BITS) transfers files (downloads or uploads) between a client and server and provides progress information related to the transfers. You can also download files from a peer.

Backup

Describes registry keys and specialized APIs for backup and restore, the Volume Shadow Copy Service (VSS), and the Windows Server Backup feature.

Common Log File System

The Common Log File System (CLFS) API provides a high-performance, general-purpose log file subsystem that dedicated client applications can use and multiple clients can share to optimize log access.

Distributed File System

The Distributed File System (DFS) functions provide the ability to logically group shares on multiple servers and to transparently link shares into a single hierarchical namespace.

Distributed File System Replication

The Distributed File System Replication (DFSR) service is a state-based, multimaster replication engine that supports replication scheduling and bandwidth throttling.

Extensible Storage Engine

The Extensible Storage Engine (ESE) is an advanced indexed and sequential access method (ISAM) storage technology. ESE enables applications to store and retrieve data from tables using indexed or sequential cursor navigation.

File Management API (FMAPI)

The File Management APIs provide a way for developers to discover and restore deleted files from unencrypted volumes. The File Management APIs also provide the ability to use a password or recovery key file for the discovery and recovery of deleted files from BitLocker-encrypted volumes.

Image Mastering API

The image mastering API enables applications to stage and burn images to CD and DVD optical storage media. Other disc-like media that lay images in the same manner can also use this API.

Imaging API

The Windows Imaging Interface Reference describes the programmatic method for managing Windows image (.wim) files.

iSCSI Discovery Library API

The iSCSI Discovery Library API allows initiators to locate any accessible target devices as well as the associated addresses with a minimal amount of required configurations.

iSCSI Software Target API

The iSCSI Software Target API provides a WMI interface for managing Microsoft iSCSI Software Target, such as creating virtual disks and presenting it to the client.

Local File Systems

Describes directory, disk, file, and volume management. Also describes Transactional NTFS (TxF).

MSXML

Microsoft XML Core Services (MSXML) allows customers who use JScript, Visual Basic Scripting Edition (VBScript), and Microsoft Visual Studio to build high-performance XML-based applications.

Offline Files

The Offline Files API allows applications to control and monitor the behavior of Offline Files programmatically.

Packaging

The packaging APIs provide support for applications that produce or consume files, called packages, that are compliant with the Open Packaging Conventions.

Remote Differential Compression

Remote Differential Compression (RDC) allows applications to synchronize data between two computers in an efficient manner.

User State Management API

The User State Management API provides an alternative way to configure and retrieve current status for the Windows components related to user state. The Windows components that expose configuration and status through these APIs are Folder Redirection, Offline Files, and Roaming Profiles.

Virtual Disk Service

The Virtual Disk Service (VDS) manages a wide range of storage configurations, from single-disk desktops to external storage arrays.

Virtual Storage

The Virtual Hard Disk (VHD) format is a publicly-available image format specification that specifies a virtual hard disk encapsulated in a single file, capable of hosting native file systems while supporting standard disk and file operations.

Windows Data Access Components

Windows Data Access Components (Windows DAC) 6.0 is a set of technologies that provide access to information across the enterprise. These technologies include Microsoft ActiveX Data Objects (ADO), OLE DB, and Microsoft Open Database Connectivity (ODBC).

Windows Storage Management API

The Windows Storage Management API is used to manage a wide range of storage configurations, from single-disk desktops to external storage arrays.

Windows Sync

The Microsoft Windows Sync API provides a way for developers to write custom synchronization providers that enable devices to synchronize data with data stores on a computer or on a network.

WMI Provider for NFS

Microsoft Services for Network File System (NFS) provides a file sharing solution that enables you to transfer files using the NFS protocol between computers running Windows and third-party operating systems.

XmlLite

XmlLite is a lightweight XML parser designed for ease of use, performance, and standards compliance.
