摘要： Infrastructure for capturing and correlating application context and database context for tuning, profiling and debugging tasks. The application context can include events such as data access events, and the database context can include events such as database server events. The events can be obtained from server tracing, data access layer tracing, and/or application tracing and written into respective log files. A data access event can indicate that an application consumed a row from a result set returned from a DBMS query. A post-processing step can correlate the application and database contexts by tokenizing strings and computing intersections between the tokenized strings. A tool inside a development environment may also suggest a query hint for the database or a data access API for the application based on the correlated context.

摘要： Infrastructure for capturing and correlating application context and database context for tuning, profiling and debugging tasks. The infrastructure extends the DBMS and application profiling infrastructure making it easy for a developer to invoke and interact with a tool from inside the development environment. Three sources of information are employed when an application is executed: server tracing, data access layer tracing, and application tracing. The events obtained from each of these sources are written into a log file. An event log is generated on each machine that involves either an application process or the DBMS server process and the log file receives log traces from different processes on a machine to the same trace session. A post-processing step over the event log(s) correlates the application and database contexts. The output is a single view where both the application and database profile of each statement issued by the application are exposed.

摘要： A data service system is described herein which processes raw data assets from at least one network-accessible system (such as a search system), to produce processed data assets. Enterprise applications can then leverage the processed data assets to perform various environment-specific tasks. In one implementation, the data service system can generate any of: synonym resources for use by an enterprise application in providing synonyms for specified terms associated with entities; augmentation resources for use by an enterprise application in providing supplemental information for specified seed information; and spelling-correction resources for use by an enterprise application in providing spelling information for specified terms, and so on.

摘要： Aggregation queries are performed by first identifying outlier values, aggregating the outlier values, and sampling the remaining data after pruning the outlier values. The sampled data is extrapolated and added to the aggregated outlier values to provide an estimate for each aggregation query. Outlier values are identified by selecting values outside of a selected sliding window of data having the lowest variance. An index is created for the outlier values. The outlier data is removed from the window of data, and separately aggregated. The remaining data without the outliers is then sampled to provide a statistically relevant sample that is then aggregated and extrapolated to provide an estimate for the remaining data. This sampled estimate is combined with the outlier aggregate to form an estimate for the entire set of data.

摘要： An index and materialized view selection wizard produces a fast and reasonable recommendation for a configuration of indexes, materialized views, and indexes on materialized views which are beneficial given a specified workload for a given database and database server. Candidate materialized views and indexes are obtained, and a joint enumeration of the combined materialized views and indexes is performed to obtain a recommended configuration. The configuration includes indexes, materialized views and indexes on materialized views. Candidate materialized views are obtained by first determining subsets of tables are referenced in queries in the workload and then finding interesting table subsets. Next, interesting subsets are considered on a per query basis to determine which are syntactically relevant for a query. Materialized views which are likely to be used for the workload are then generated along with a set of merged materialized views. Clustered indexes and non-clustered indexes on materialized views are then generated. The indexes, materialized views and indexes on materialized views are then enumerated together to form the recommended configuration.

摘要： Assignment algorithm for automatically making assignments between documents and document reviewers for a review process. If the automated assignments need adjusting, a coordinator can manually refine the assignment(s). The assignment algorithm facilitates the automated assignment process based on inputs related to a constraint and/or a preference. The constraints and preferences include, but are not limited to, a conflict of interest, a minimum number of reviews, a maximum number of submissions, a partial assignment, bidding preferences, and health metrics. Once the assignments have been made, histograms can be generated that present an overview of certain health metrics, further allowing refinement of the assignment process.

摘要： A method of estimating results of a database query, the results are estimated by performing a sampling of weighted tuples in a database based on a probability of usage of tuples required in executing a workload. A probability is associated with each tuple sampled. An aggregate is computed over values in each sampled tuple while multiplying by the inverses of the probabilities associated with each tuple sampled.
