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： A tool facilitating static analysis for database applications, such that the static analysis tool (SAT) can significantly enhance the ability for developers to identify security, correctness and performance problems in database applications during the development phase of an application lifecycle. A static analysis tool for database applications presents a framework for database applications using the ADO.NET data access APIs. The SAT framework consists of a core set of static analysis services upon which verticals such as workload extraction, SQL injection detection, identifying data integrity violations, and SQL performance analysis are built using the core services.

摘要： Systems and methodologies that split a table into a plurality of sub-tables, and vertical partitions. By analyzing an associated work load to determine frequently referenced columns, the subject invention supplies a compromise among various vertical partitioning strategies (e.g., candidate selection for table spilt) via a merging act, such that the table is split optimally for the work load taken as a whole Accordingly, an incoming query can optimally reference only required columns.

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： The subject disclosure pertains to logical schema tuning for databases. Mechanisms are provided for automatically recommending one or more logical schema transformations to improve database performance with respect to workload and data characteristics. Furthermore, several potential schema transformations including desirable properties are presented including mapping tables, vertical partitioning, frequent value elimination and type and attribute conversion. Still further yet, disclosed is a mechanism for rewriting database operations (e.g. queries, updates . . . ) for an optimized schema to ensure correct evaluation.

摘要： An outlier index for a database and a given workload is generated by identifying sub-relations of tuples in the database induced by selection and group by conditions in queries in the workload. A variance is then generated for values in each sub-relation. Sub-relations having higher variances are selected, and outliers from such sub-relations having higher variances are generated.
