A computing system runs a productivity application that maintains an integrated, time ordered revision/undo stack. Entries in the revision/undo stack identify revision operations that a user has made to a document and corresponding undo operations that can be executed to undo the revision operation. The computing system detects an undo input indicative of a user actuating un undo actuator to undo a previous operation, that is prior to a most current operation that the user has performed. An operational transform system identifies an undo operation in the undo stack, corresponding to the revision that the user selected in the revision/undo stack. The operational transform system traverses the revision/undo stack to identify subsequent operations that were performed subsequent to the previous operation, and identifies one or more transforms to be applied to the undo operation based upon the identified subsequent operations. The operational transform system then transforms the undo operation, using the transformation function, and applies the transformed undo operation to the document.

A consumer oriented data service is provided. A data collaboration service initiates operations to provide access to data from multiple sources by managing a data table of aggregate data fields based on a request from a client application. The request includes a consumer identification and data queries. An ownership of the data table is assigned based on the consumer identification. Local data fields identified in the data queries are inserted into the data table and populated with local datasets stored in the queries. External data fields identified in the data queries are inserted into the data table and populated with links to external datasets stored in external data sources.

Methods and computer-readable media are provided for refreshing a page validation token. In response to a request for a form from a client, a server responds with the requested form, a page validation token, and a page token refresh program. The client executes the page token refresh program in response to a request to post the contents of the form to the server computer. The page token refresh program determines whether a preset period of time has elapsed since server computer generated the page validation token. If the period of time has not elapsed, the form is posted to the server with the page validation token and processed by the server computer. If the page timeout has elapsed, the page token refresh program refreshes the page validation token prior to posting the form by requesting an updated page validation token from the server.

Reducing the number of inquiries required to determine access rights accorded to documents, in particular documents stored at a Web site, is disclosed. Upon receipt of a request for documents, a list of the documents is opened by the receiving server and data denoting the user access level of every document on the list is determined. Then, the resulting series of access levels is filtered to remove any access levels not available to the requestor. Next, a document query, including as a condition that any returned list of documents only include documents having an access level included on the filtered series of access levels, is generated. The resulting document data is then embedded in a Web page and sent to the requestor.

Access trimmed user interface

A system and method are provided for delivering batches of data to a client, while maintaining the client's state in the accessed database. The system and method eliminate the need for a web server to maintain the location of any given client within a database. Accordingly, the web server operates with greater efficiency, because it is freed from having to maintain the state of any given client within a database and need not create or maintain a partitioned database. Maximum and minimum values of any data previously requested and received by the client are maintained. These maximum and minimum values are later used within a novel set of Structured Query Language (SQL) statements to indicate the user's state within the database. By maintaining minimum and maximum reference values, the user's state within the accessed database can be maintained without storing any information on the web server. The next and previous batches are successfully obtained by comparing these stored reference values to the database so that the user can quickly move between adjacent batches of records. The invention provides a simple and elegant means for maintaining a user's state within a database, without requiring the use of a web server's resources or the creation of a partitioned database.
