As part of managing the loading of data from a source onto a database, according to an example, an interface through which a user is to define logic related to the loading of the data onto the database is provided. The user-defined logic pertains to at least one of a user-defined location identification of the source, a user-defined filter to be applied on the data, and a user-defined parsing operation to be performed on the data to convert the data into an appropriate format for the database. In addition, the user-defined logic is received and the user-defined logic is implemented to load the data onto the database.

User-defined loading of data onto a database

In a method for managing transfer of data from a source machine cluster to a destination machine cluster, information relevant to the transfer of data from the source machine cluster to the destination machine cluster is accessed. In addition, a data transfer operation that substantially optimizes the transfer of the data based upon the accessed information is determined. Furthermore, the determined data transfer operation is implemented to transfer the data from the source machine cluster to the destination machine cluster.

A database management system (DBMS) client calls an interface of a DBMS server to execute a statement that has been prepared to be executed in batch form in relation to a database managed by the DBMS server. The DBMS client provides a different batch of data to the DBMS server each time the DBMS client calls the interface. The DBMS server processes the different batch of data in accordance with the statement that has been prepared, to effectuate execution of the statement at the DBMS server on a batch basis in relation to the different batch of data. The DBMS server returns results of processing the different batch of data to the DBMS client, such that the DBMS client receives intermediate feedback as to status of processing the statement prior to the statement being completely processed.

Methods, systems and program products for database storage. In one implementation, data of a projection of a database is stored at least partly in grouped ROS format and partly in column format based on patterns of updating the projection data. The projection data is updated so that the updated projection is stored partly in grouped ROS format and partly in column format.
