摘要： Techniques for replicating modified data to a hierarchical database. A first list comprises records included in a set of records before at least one modification thereto. A second list comprises records included in the set of records after the at least one modification thereto. For each pre-modification record included in the first list and each post-modification record included in the second list having equal identifying values, a target record at the database and having a matching identifying value is modified. Specifically, if both records include corresponding indexes, information about a structure pointed to by the pre-modification record is removed from an index included in the target record, and information about a structure pointed to by the post-modification record is added to the index. If neither record includes an index, the target record is modified to contain at least one changed value included in the post-modification record.

摘要： A method, system, method and computer program product for retrieving data. Records are retrieved from a hierarchical database. The records are categorized into a plurality of record types. Each record comprises a unique identifier field. A record map contains zero or more entries. Each entry comprises an identifying value, data from at least one record and a set of Boolean flags. Each flag corresponds to a record type. A computer iterates over the retrieved records. Data from each record is stored at an entry in the record map having an identifying value equal to the value included in the unique identifier field of the record. Moreover, the flag in this entry which corresponds to the record type of the record is set. Inner joins and outer joins are then performed using the contents of the record map.
