Abstract: Modifications made to files (e.g., stub files) within a distributed file storage system over a defined time period are determined. Moreover, the distributed file storage system employs a tiered cloud storage architecture. In one aspect, snapshots of a stub file can be generated at different instances of time. Further, metadata of the stub file within the different snapshots can be compared to determine whether the stub file has been modified. As an example, the metadata can include cache metadata that describes the content within the cache of the stub file and/or mapping metadata that describes the content within cloud storage that is referenced by the stub file.

Abstract: A method is provided for controlling whether transactions applied against a database go forward or are aborted on a transaction processing system. A tracking engine identifies an uncompleted transaction to be joined, joins the uncompleted transaction, and collects selected attributes of the joined uncompleted transaction. The collected attributes of the joined uncompleted transaction are compared against rules in a rules engine to determine whether the joined uncompleted transaction goes forward or is aborted. Alternatively, the joined uncompleted transaction is automatically modified so that the collected attributes are in compliance with the rules in the rules engine, thereby allowing the joined uncompleted transaction to go forward and be applied against the database of the transaction processing system.

Abstract: Technology for improving evaluation of policies comprising multiple rules is disclosed. By generating a policy evaluation tree controlling, for any given policy state, which rules should be evaluated next, policy optimization can be performed off-line prior to policy evaluation. For a policy, a policy evaluation tree can be generated such that each node in the tree corresponds to a policy state and each child node corresponds to a policy state that may result from an action that may be taken from its parent policy state. Policy evaluation trees may be generated by iteratively generating, from an initial policy state, possible next states as child states until a result of the policy is determined. Some next possible policy states may be pruned from the tree based on conditions such as having a high cost of evaluation compared to the likelihood a rule will yield an interesting result.

Abstract: A system is configured to obtain data for a user. The data may describe actions that the user has performed in an application and identify points in time associated with the actions. A point in time may include a point in time at which one of the actions was performed. The system is configured to analyze the data to determine, for each action, a score for each point in time. The score, for a particular point in time, may be determined based on one or more points in time at which the action was performed, and may be determined from a number of times that the action was performed at the particular point in time. The system is configured to provide the user with a functionality to perform a particular action based on the scores determined for the particular action for the set of points in time.

Abstract: A computing device hosting a website of a business may be operable to receive a first search input comprising a term submitted via a search bar on the website. Upon performing an internal search for the term with no result, the computing device may output information on the no-result. The computing device may then perform, using one or more external search engines, a search for the term. Search results of the search, performed using the external search engine(s), may be analyzed. Based on a result of the analysis, one or more particular character strings related to the term may be identified. The computing device may generate and store, based on the identifying of the particular character string(s), one or more alternative search suggestions. Upon subsequently receiving an input comprising at least a portion of the term entered in the search bar, the computing device may output the alternative search suggestion(s).

Abstract: In one aspect, a computer-implemented method for managing conflicts in a logical component hierarchy is provided. The logical component hierarchy includes an ancestor component and a descendant component associated with the ancestor component. The method uses a computer device in communication with a memory. The method includes determining, by the computer device, a requirement to replace the descendant component, within the logical component hierarchy, with an overriding component. The overriding component is associated with the ancestor component by an overriding reference. The method also includes replacing the descendant component with the overriding component within the logical component hierarchy.

Abstract: A virtual database is attached to a server database management system (“DBMS”) such that the DBMS believes it needs to recover the database to a last known point of consistency. In order to perform this recovery, the DBMS requests the transaction log file entries to be read from what it believes is the database's transaction log file. However, the requests are intercepted and translated into requests to read the transaction log portion of the backup file. The DBMS then uses the transaction log records to bring the database to a point of transactional consistency, unaware that the log records are actually being sourced from the backup file. All changes made to the data during the recovery phase and subsequent execution of any TSQL statements are routed into a cache file. Accordingly, a “virtual” database is created and used by the server DBMS engine as if it were a real database.
