Abstract: Method, system, and computer program product for transferring data from transactional data sources to partitioned databases are provided. One or more messages from a transactional data source are read. Each message includes one or more records to be inserted into a database comprising a plurality of partitions. One of the partitions of the database in which the one or more records of each message are to be inserted is then identified. A transaction is initiated to insert the one or more records of each message into the one partition and to delete the one or more messages from the transactional data source. The transaction is committed only when insertion of the one or more records of each message into the one partition and deletion of the one or more messages from the transactional data source succeed.

Abstract: Method, computer program product, and system for transferring data from positional data sources to partitioned databases are provided. A record is read from a positional data source. The record is to be written to one of a plurality of partitions of a database. A position of the record in the positional data source is obtained. A transaction is initiated to write the record to the one partition and to store the position of the record in the database. The transaction is committed after the record is successfully written to the one partition and the position of the record is successfully stored in the database.

Abstract: Method, computer program product, and system for transferring data to database partitions are provided. A transaction is initiated to insert one or more records into a partition of a database. At least one of the one or more records is then saved in binary form to a dump table in the database as a part of the transaction in response to the insertion of the at least one record into the partition having failed as a result of the at least one record not satisfying a predetermined condition. In response to the saving of the at least one record in binary form to the dump table having failed, the transaction is rolled back.

Abstract: In a database processing system with a partitioned database that provides relational extenders to support storage of and access to complex data types, metadata table rows are collocated with corresponding relational table partitions. Image indexes are generated and stored at system nodes with their corresponding relational table partitions. Image query processing is conditioned to account for the partitioned structure of the database.

Abstract: This invention is directed to relational extenders for a computer-based relational database. Each relational extender includes at least one column, in a first, business, table containing a user defined application database, dedicated to object handles for defining the complex data type of an object; a second, attribute, table containing at least one column defining a unique characteristic associated with the one object and one column dedicated to containing the object handle; and a third, metadata, table containing at least one column defining a common characteristic associated with all objects defined within the business table and one column dedicated to containing the object handle and at least one column dedicated to containing a reference to object data associated with the object.
