摘要:
In one embodiment, the method includes profiling a data file comprising one or more fields of data. The one or more fields of data contain an item of data; that is, a character, or group of characters that are related. Further, the method includes generating one or more profiling attributes based on profiling the data file. In an example, the one or more profiling attributes refer to profiling information relating to pattern, structure, content and format of data. Further, the method includes selecting at least one of the generated one or more profiling attributes and generating a validation rule based on the selected at least one profiling attribute.

Various embodiments of systems and methods for evaluating a trust value for a report are disclosed herein. The method includes obtaining one or more reports by the computer, where the reports are formed of one or more fields of data. An end-to-end lineage for the data is determined to trace the data back to the data source system from which the data had originated initially. Further, the method includes validating each of the multiple data source systems including intermediate tables, and determining a data quality score for each of the multiple data source systems. A trust value for the report is calculated based on the data quality scores for the one or more data source systems and intermediate tables, and rendered along with the report.

摘要:
A computer readable storage medium includes executable instructions to assess system cache resources, inter-process communication requirements and staging requirements to divide an extract, transform, load (ETL) dataflow task into a plurality of sub-tasks. The sub-tasks are then executed in parallel on distributed resources.

摘要:
A method and system are presented of automatically suggesting rules for data stored in a table, with the table comprising a plurality of columns. The table is profiled to identify a content type for each of one or more of the plurality of columns. A rule knowledge base is accessed to locate rules specified for identified content types. Then, one or more of the located rules specified for identified content types are presented as suggestions. Acceptance of one or more of the suggested rules is received from a user, and the received validations are stored in the rule knowledge base. The accepted rules are applied to data for quality detection and monitoring. Embodiments are also described where columns are suggested based on a given rule.
摘要:
An integrated circuit (IC) comprises a rectifier/regulator circuit coupled to receive an ac source voltage and output a regulated dc voltage. The rectifier/regulator circuit includes first and second switching elements that provide charging current when enabled. The first and second switching elements do not provide charging current when disabled. A sensor circuit is coupled to sense the regulated dc voltage and generate a feedback control signal coupled to the rectifier/regulator circuit that enables the first and second switching elements when the regulated dc voltage is above a target voltage, and disables the first and second switching elements when the regulated dc voltage is below the target voltage.
摘要:
A temperature independent reference circuit includes first and second bipolar transistors with commonly coupled bases. First and second resistors are coupled in series between the emitter of the second bipolar transistor and ground. The first and second resistors have first and second resistance values, R1 and R2, and third and second temperature coefficients, TC3 and TC2, respectively. The resistance values being such that a temperature coefficient of a difference between the base-emitter voltages of the first and second bipolar transistors, TC1, is substantially equal to TC2×(R2/(R1+R2))+TC3×(R1/(R1+R2)), resulting in a reference current flowing through each of the first and second bipolar transistors that is substantially constant over temperature. A third resistor coupled between a node and the collector of the second bipolar transistor has a value such that a reference voltage generated at the node is substantially constant over temperature.
