Abstract: A system and method for returning a sorted result set of information corresponding to files in a file system that have properties which match user query criteria. A view index of files sorted by at least one property common to those files is provided. The view index may be synchronously or asynchronously updated as files are changed. Upon receipt of query requesting a result set of files corresponding to properties in the query criteria, the view index is compared to determine if the properties are maintained in an order that corresponds to the query criteria. If so, the view index is accessed to locate information of files that have the matching properties, and the result set is returned. The view index may be associated with a view description of the identities and order of the properties. The comparison to determine if a view index corresponds with the criteria may then be performed against the view description.

When a user adds a new word to the local customized dictionary, an Internet request is sent to the vendor computer to add the new word to the dictionary of approved words. The user is notified by an Internet message from the vendor computer if the requested word is misspelled. The database of requested words from all users is reviewed periodically and utilized to update the approved dictionary. The updated dictionary is periodically released to the users as an upgrade to the local main dictionary.

Abstract: A method and apparatus for parallelizing operations that change a database is provided. A coordinator process receives a statement that requires data to be written into the database. In response to the statement, the coordinator process assigns granules of work to multiple processes. Each of the multiple processes executes the granule of work by writing to the database a distinct portion of the set of data that is to be added to the database. The various portions of data are then merged to create the set of data to be added to the database.

Abstract: A method and apparatus for saving and restoring persistent objects in a distributed object-oriented programming environment. This invention maintains persistent values for individual attributes and or instance variables. Attribute persistence is implemented using an interface that is inherited by any class that wants to have persistent attributes. The interface provides load.sub.-- attribute and store.sub.-- attribute methods that provide TypeCode based encoding and decoding. The methods provide improved performance by maintaining a cached copy of the encoded attribute and its TypeCode in memory in addition to the copy that exist in external storage. This allows the load.sub.-- attribute method to return the attribute without having to access external storage. Performance is enhanced during the object restoration process by restoring only the attribute values currently needed instead of the entire object.
