Abstract: A method of incorporating the influence of diffusion into the CPMG-based T2 measurement for one or more of the following: water cut measurement; performing inline measurements of flow rate; density; and rheology of a flowing fluid. The method includes conducting a “standard T1/T2 experiment” at least twice by providing one scan without a field gradient during the CMPG echo train. Then, providing a second scan with the application of a gradient, where in the second experiment the measured T2 (T2app) is affected solely by water diffusion, thus shifting cross peaks which represent water on the first T1/T2 spectrum to lower T2 values on the second spectrum.

The method further includes a computer processor placing each of the plurality of transactions, of the database query, in respective chronological order, in a scheduling queue. The method further includes a computer processor determining that at least a first transaction and a second transaction within the plurality of transactions each contains one or more transaction delineation descriptions. The method further includes computer processor responding to the determination that the first transaction and the second transaction, within the plurality of transactions, each contains one or more transaction delineation descriptions, and merging the first transaction and the second transaction to create a merged transaction combination and merging also includes combining two or more table-scan operations.

Abstract: A method, system and computer program product for providing consolidated access to data of a plurality of source databases. Tables of each of the source databases are replicated to a shared accelerator. The source DBMSs are configured to dispatch queries to the accelerator for accelerating query execution. The accelerator is configured such that the replicated tables can only be accessed by the source DBMS having provided said tables for executing a dispatched query. A user can select one of the source DBMSs to act as a consolidated DBMS—C-DBMS. The C-DBMS provides the consolidated access. The user is enabled to select tables managed by another one of the DBMSs. In response to receiving the selection of the tables, the accelerator is re-configuring such that the C-DBMS is granted access also to the copies of the selected tables in the accelerator.

Abstract: A distributed database system (or federated database system) where a catalogue is used to store metadata descriptive of data containers for the constituent database system(s) and/or accelerator system(s) of the federated database. In response to the generation of the trigger signal corresponding to a database definition language (DDL) statement, the accelerator system updates metadata in the catalogue.

Abstract: Aspects of the invention include processing queries in a database system having a first database engine and a second database engine. A first instance of a first table is stored in the first database engine in plaintext. At one predefined column of the first table is encrypted, resulting in a set of encrypted columns, using a cascade encryption scheme that includes a set of ordered encryption methods. A subset of the set of columns is stored in a second instance of the first table in the second database engine. An encryption method of the cascade encryption scheme that allows a query operation of a received query on data encrypted with the identified encryption method is identified. The identified encryption method is used to rewrite the query, and the rewritten query is executed using the second instance of the first table.

Abstract: Loading a set of data into a target database management system (DBMS) from a source DBMS to increase workload performance and decrease resource usage is provided. Using a size and a change rate of tables eligible to be offloaded to the target DBMS, a total central processor unit (CPU) cost corresponding to loading the set of data into to the target DBMS and workload cost savings corresponding to executing one or more workloads on the target DBMS is determined based on a set of one or more load strategies. The total CPU cost is compared with the workload cost savings of each load strategy. An optimal load strategy is selected based on comparing the total CPU cost with the workload cost savings of each load strategy. The set of data is automatically loaded into to the target DBMS from the source DBMS in accordance with the selected optimal load strategy.
