A method for updating a computer program includes receiving a program hosted on and configured to be executed by a first computing system. The program is analyzed to obtain characterization of the program's lineage, architecture, and operation. Lineage includes relationships among elements of the program, architecture includes a characteristic of the data source, the data target, and processors configured to process the data contained in data records, and operation includes processes that are executed to process the data from the data records. A characterization is received of an update to be made to the program; when the program is modified according to the update, at least some of the modified program is configured to be hosted on and executed by a second computing system. The program is modified to implement the update to generate the modified program.

Automated modification of computer programs

In an aspect, a method for migrating data records to a federated database system includes obtaining data records from a data source in a first federated database system; generating a data snapshot file based on the obtained data records and data indicative of a characteristic associated with the obtained data records; generating a hash of the data snapshot file to prevent modification of the data snapshot file; storing the data snapshot file and the generated hash in a data storage; migrating the obtained data records from the data snapshot file to a data target in a second federated database system, the migrating including: retrieving the data records from the data snapshot file stored in the data storage; providing the retrieved data records to the data target according to a mapping between a characteristic of the data source and a characteristic of the data target.

Migration of datasets among federated database systems

A data processing system with a dataset multiplexer that enables applications to be written to specify access to datasets as operations on logical datasets. During execution of an application by the data processing system, operations that access a dataset are implemented by accessing an entry in a dataset catalog for the logical dataset. That entry includes information to access the physical data source storing the logical dataset, including conversion of data from the format of the physical data source to the format of the logical dataset. An entry in the catalog may be created based on registration of a data source with the dataset multiplexer and may be updated automatically based on changes in storage of the dataset. This maintenance of the catalog may be partially or totally automated such that the system automatically adjusts to any changes in storage of the dataset without need for modification of any application.

Dataset multiplexer for data processing system

A method for generating an updated graph based on a base graph includes identifying differences between a base graph and each of a source and a target graph. The specification of each graph defines nodes representing data processing components defining operations for processing data, and links representing flow of data. The identifying includes: comparing specifications of base and source graphs to identify a first set of differences between the base and source graph, and comparing specifications of base and target graphs to identify a second set of differences between the base and the target graph. The method includes characterizing a correspondence between the differences in the first set and the differences in the second set, determining a set of combined differences based on the correspondence and the first and second sets of differences, and generating the updated graph based on the base graph and the set of combined differences.

Updating executable graphs

Managing sets of parameter values includes: receiving a plurality of sets of parameter values for a generic computer program, and processing log entries associated with executions of instances of the generic computer program, each instance associated with one or more parameter values. The processing includes: analyzing the generic computer program to classify each of one or more parameters associated with the generic computer program as a member of either a first class or a second class; processing a log entry associated with an execution of a first instance of the generic computer program to form a particular set of parameter values; and determining whether to add the particular set of parameter values to the plurality of sets of parameter values based on a comparison of a first identifier for the particular set of parameter values to identifiers for at least some of the sets of parameter values.

Managing parameter sets

Managing lineage information includes: receiving lineage information representing one or more lineage relationships among two or more data processing programs and two or more logical datasets; receiving one or more runtime artifacts, each runtime artifact including information related to a previous execution of a data processing program of the two or more data processing programs; and analyzing the one or more runtime artifacts and the lineage information to determine one or more candidate modifications to the lineage information.
