Patent number: 8370511Abstract: Systems and methodologies are provided as part of a computing environment that implements an enhanced tabular data stream (TDS) protocol. Such enhanced TDS protocol can mitigate synchronization inconsistencies between client and servers, improve robustness of the data transfer, facilitate password specification as part of login procedures, and reduce administration overhead. Various headers are provided as part of the data stream protocol, and a versioning scheme is established that facilitates proper communication between servers and clients having different release dates and versions of the TDS protocol.Type: GrantFiled: January 4, 2008Date of Patent: February 5, 2013Assignee: Microsoft CorporationInventors: Shrinivas Ashwin, Christian Kleinerman, Ganapathy Subramaniam Krishnamoorthy, Joel M. Soderberg

Patent number: 8112383Abstract: Various embodiments of the present invention enable functions, procedures, and triggers to be written in any of the .NET languages and executed by the RDBMS. User code can access data from the local or other SQL servers using the SQL Programming Model and both the SqlServer or SqlClient implementations respectively. Moreover, to improve upon the previous extensibility mechanism, a set of APIs (commonly known as “the in-process provider” or “inproc provider”) is utilized to provide efficient and easy to use data access while running inproc, a data access API that is an implementation of the ADO.net programming model.Type: GrantFiled: February 10, 2004Date of Patent: February 7, 2012Assignee: Microsoft CorporationInventors: Alazel Acheson, Shrinivas Ashwin, Jose A. Blakeley, Peter Carlin, Erik Ismert, Christian Kleinerman, Ganapathy Subramaniam Krishnamoorthy, Girkumar Nair

Patent number: 7890508Abstract: Mechanisms and techniques for database fragment cloning and management are provided. A database object, such as a table, rowset or index, is divided into fragments. Each fragment is cloned to create cloned fragments, which operationally are substantially identical to one another. One or more of the cloned fragments may be designated as a primary cloned fragment for performing database operations or as a secondary cloned fragment for serving as backup. Updates to each fragment are implemented on the primary cloned fragment and are then propagated from the primary cloned fragment to the corresponding secondary cloned fragments. A cloned fragment can go offline, becoming unavailable to be updated. When the cloned fragment returns online, the cloned fragment is refreshed with data included in the primary cloned fragment. While being refreshed, the cloned fragment may continue to be updated.Type: GrantFiled: August 19, 2005Date of Patent: February 15, 2011Assignee: Microsoft CorporationInventors: Robert H. Gerber, Balan Sethu Raman, James R. Hamilton, John F. Ludeman, Murali M. Krishna, Samuel H. Smith, Shrinivas Ashwin

Patent number: 7548901Abstract: A number of members of a user defined type may be designated as delayable members. During an initial fetch of the type, the type may be returned from the database without the delayable members, thereby preserving valuable bandwidth and reducing the amount of time required to perform the initial fetch. Upon request, selected delayable members may be re-fetched from the database at a later time without returning the other members provided during the initial fetch.Type: GrantFiled: June 29, 2004Date of Patent: June 16, 2009Assignee: Microsoft CorporationInventors: Shrinivas Ashwin, Christian Kleinerman, Eugene Zabokritski, Ganapathy Krishnamoorthy, Giri Nair

Patent number: 7437346Abstract: Various embodiments of the present invention are direct to the utilization of Blob Handles (BHs) which are an internal representation of a large value. BHs are immutable and stateless references to a large data object. The structure of a BH contains enough information to return an ILockBytes interface in order to provide access to the corresponding large data block, and a BH can also return information regarding its own lifetime description. A BH can be completely described using (a) a pointer to the beginning of BH data and (b) the byte-length of the BH.Type: GrantFiled: February 10, 2004Date of Patent: October 14, 2008Assignee: Microsoft CorporationInventors: Shrinivas Ashwin, Jose A. Blakeley, Peter Carlin, Jun Fang, Ajay Kalhan, Christian Kleinerman, Stefano Stefani, Aleksandras Surna, Honggang Zhang
