20090144235 | METHOD FOR AUTOMATED DESIGN OF RANGE PARTITIONED TABLES FOR RELATIONAL DATABASES - A workload specification, detailing specific queries and a frequency of execution of each of the queries, and a set of partitions, are obtained for the database, as inputs. A number of candidate tables are identified for the database, the tables having a plurality of attributes. A chosen attribute is allocated for each of the tables, to obtain a set of tables and a set of appropriate partitions for each of the tables. | 06-04-2009 |

20090193041 | METHOD FOR AUTOMATED DESIGN OF ROW COMPRESSION ON TABLES IN A RELATIONAL DATABASE - A workload specification is obtained for the database. Based on the workload specification, candidate ones of the tables are identified and ranked. Compression impact is evaluated for the candidate ones of the tables. A design for the database is developed, specifying at least one of: (i) which of the tables should be compressed, and (ii) which of the tables should not be compressed. | 07-30-2009 |

20090063398 | STATISTICS COLLECTION FOR DATABASE TABLES - A method and system for collecting statistics on database tables. In one embodiment, the method includes identifying a plurality of tables for statistics collection, wherein each table of the plurality of tables are remote tables; examining at least one attribute for each table identified for statistics collection; prioritizing the tables for statistics collection based on the at least one attribute; and collecting statistics on the identified tables in a priority sequence. | 03-05-2009 |
20090063399 | INDEX SELECTION FOR XML DATABASE SYSTEMS - A method, system, and computer program product for selecting indexes to be created over XML data are provided. The method, system, and computer program product provide for receiving a workload for the XML data, the workload including one or more database statements, and utilizing an optimizer to recommend a set of one or more path expressions based on the workload received, wherein the set of one or more path expressions is to be used to create one or more indexes over the XML data. | 03-05-2009 |
20090089306 | Method, System and Article of Manufacture for Improving Execution Efficiency of a Database Workload - Disclosed is a data processing system implemented method, a data processing system and an article of manufacture for improving execution efficiency of a database workload to be executed against a database. The database includes database tables, and the database workload identifies at least one of the database tables. The data processing system includes an identification module for identifying candidate database tables being identifiable in the database workload, the identified candidate database tables being eligible for organization under a clustering schema, a selection module for selecting the identified candidate tables according to whether execution of the database workload is improved if the selected identified candidate table is organized according to the clustering scheme, and an organization module for organizing the clustering schema of the selected organized identified candidate tables prior to the database workload being execution against the database. | 04-02-2009 |
20130080441 | INDEX SELECTION FOR XML DATABASE SYSTEMS - A method, computer-implemented system, and computer program product for creating indexes over XML data managed by a database system are provided. The method, computer-implemented system, and computer program product provide for receiving a workload for the XML data, the workload including one or more database statements, utilizing an optimizer of the database system to enumerate a set of one or more path expressions by creating a virtual universal index based on the workload received and matching a path expression to the virtual universal index, and recommending one or more path expressions from the set of one or more candidate path expressions to create the indexes over the XML data. | 03-28-2013 |
